The volume of the cuboid to be approximately 1.8cm³.

In this case, we are given that the volume of the small cube is 1cm³. Therefore, using the formula, we can solve for the length of its side as follows:

1cm³ = s³

Taking the cube root of both sides: ∛(1cm³) = ∛(s³) 1cm = s

Hence, the length of the side of the small cube is 1cm.

Then, we can estimate the other two dimensions of the cuboid as follows:

   • The width (w) could be a little more than the length of the side of the small cube, say 1.2a.

   • The height (h) could also be a little more than the length of the side of the small cube, say 1.5a.

Therefore, using the formula for the volume of a cuboid, we can estimate the volume of the cuboid as follows:

V = lwh V = a × 1.2a × 1.5a V = 1.8a³

Substituting the value of 'a' as 1cm, we get:

V ≈ 1.8cm³

The complete question is:

Based on the provided tables, the correct answer is c. Guitarists were significantly less anxious than pianists and drummers, and drummers were significantly less anxious than pianists.

To reach this conclusion, follow these steps:
1. Look at the "Estimates" table, which provides the mean anxiety levels and 95% confidence intervals for each instrument group.
- Guitar: Mean anxiety = 72.633
- Piano: Mean anxiety = 85.852
- Drums: Mean anxiety = 98.225
2. Examine the "Pairwise Comparisons" table, which presents the mean differences in anxiety levels between the instrument groups and the significance levels (Sig.) after applying the Bonferroni correction for multiple comparisons.
- Guitar vs Piano: Mean difference = -13.219, Sig. = .008 (significant)
- Guitar vs Drums: Mean difference = -25.592, Sig. = .000 (significant)
- Piano vs Drums: Mean difference = -12.373, Sig. = .009 (significant)
3. Since all three pairwise comparisons are significant at the .05 level, it means that the anxiety levels among the groups are significantly different. Thus, guitarists have lower anxiety than pianists and drummers, and drummers have lower anxiety than pianists.

The tables show that there is a significant difference in anxiety levels among the different instruments. Drummers had the highest anxiety levels, followed by pianists, and guitarists had the lowest anxiety levels. The pairwise comparisons also show that the anxiety levels of guitarists were significantly lower than both drummers and pianists. Therefore, the answer is option b: Guitarists were significantly less anxious than drummers but were about as anxious as pianists, and drummers were about as anxious as pianists. The tables also provide information on the interval and difference in anxiety levels among the instruments.

If a and b are n × n, b is invertible, and ab is invertible, then a is also invertible.

To show that a is invertible, we need to find an inverse matrix [tex]A^-^1[/tex]such that A[tex]A^-^1 = A^-^1A[/tex] = I (the identity matrix).

Let's begin by using the hint provided and letting c = ab. We know that b is invertible, so we can multiply both sides of c = ab by b^-1 (the inverse of b) to get:

[tex]c(b^-^1) = ab(b^-^1)c(b^-^1) = a(bb^-^1)c(b^-^1) = aIc(b^-^1) = a[/tex]

Now we substitute c = ab back into the equation to get:

[tex]ab(b^-^1) = a[/tex]

Next, we can use the fact that ab is invertible to say that there exists some inverse matrix[tex](ab)^-^1[/tex] such that [tex](ab)(ab)^-^1 = (ab)^-^1(ab)[/tex] = I. Multiplying both sides of this equation by [tex]b^-^1[/tex], we get:

[tex]a(bb^-^1)(ab)^-^1 = (ab)^-^1(bb^-^1)a^-^1[/tex]
[tex]aI(ab)^-^1 = (ab)^-^1I[/tex]
[tex]a(ab)^-^1 = (ab)^-^1[/tex]

So we have shown that a multiplied by the inverse of ab is equal to the inverse of ab. This means that a must also be invertible, since the inverse of ab exists and we can simply multiply it by a to get the inverse of a. Therefore, we have proven that if a and b are n × n, b is invertible, and ab is invertible, then a is also invertible.

The situation could be described by the expression d+1/2 is an option (C). Lela walked 1 mile yesterday, and d miles fewer today.

What is the equivalent expression?

Equivalent expressions are expressions that perform the same function despite their appearance. If two algebraic expressions are equivalent, they have the same value when we use the same variable value.

d+1/2 is an abbreviation for "d plus one-half."

It describes a situation in which a quantity (represented by d) is increased by half.

For example, if Lela walked d miles yesterday and wants to walk another half mile today, she might use the term d+1/2 to indicate her total distance walked today.

Alternatively, if Lela wanted to walk half as far today as she did yesterday, the equation would not apply since the quantity being added or subtracted is a variable amount (d/2) rather than a fixed amount (one-half).

Hence, the situation could be described by the expression d+1/2 is option (C). Lela walked 1 mile yesterday and d miles fewer today.

The probability that at least one computer fails to solve the problem is approximately 0.431 or 43%, which is option (b).

The probability that a single computer solves the problem is 0.92. Therefore, the probability that a single computer fails to solve the problem is:

P(failure) = 1 - P(success) = 1 - 0.92 = 0.08

Since the computers are working independently, the probability that all ten computers solve the problem is:

P(all computers solve) = 0.92¹⁰= 0.569

The probability that at least one computer fails to solve the problem is the complement of the probability that all computers solve the problem:

P(at least one computer fails) = 1 - P(all computers solve) = 1 - 0.569 = 0.431

The area of a triangle with vertices (6, 6), (2, 4), and (0, 8) is 4√10 square units.

To find the area of a triangle with vertices (6, 6), (2, 4), and (0, 8), we can use the formula:

Area = 1/2 * base * height

First, we need to find the base and height of the triangle. We can use the distance formula to do this:

Base = distance between (6, 6) and (2, 4) = √[(6-2)^2 + (6-4)^2] = √20
Height = distance between (0, 8) and the line containing (6, 6) and (2, 4). To do this, we first find the equation of the line:

y - 6 = (6-4)/(6-2) * (x-6)
y - 6 = 1/2 * (x-6)
y = 1/2x + 3

Then we find the distance between point (0, 8) and the line y = 1/2x + 3:

Height = |1/2*0 - 1*8 + 3| / √(1^2 + 1/2^2) = 4√5/5

Now we can plug in the base and height into the formula:

Area = 1/2 * √20 * 4√5/5 = 4√10 square units

Therefore, the area of the triangle is 4√10 square units.

a. To find the probability that the chain will be in state 2 at time n+2, given that it is currently in state 3 at time n, we need to look at the (3, 2) entry of the matrix P^2, which represents the probability of transitioning from state 3 to state 2 in two steps:

P^2 = P * P = [[1/4, 1/4, 0, 1/20], [1, 0, 0, 0], [1/2, 0, 1/2, 0], [1/4, 1/4, 1/4, 1/4]] * [[1/4, 1/4, 0, 1/20], [1, 0, 0, 0], [1/2, 0, 1/2, 0], [1/4, 1/4, 1/4, 1/4]]

So the probability of transitioning from state 3 to state 2 in two steps is 1/20. Therefore, the probability of being in state 2 at time n+2, given that the chain is currently in state 3 at time n, is 1/20.

b. To find the probability that the chain will be in state 3 at time n+3, given that it is currently in state 1 at time n, we need to look at the (1, 3) entry of the matrix P^3, which represents the probability of transitioning from state 1 to state 3 in three steps:

P^3 = P * P^2 = [[1/4, 1/4, 0, 1/20], [1, 0, 0, 0], [1/2, 0, 1/2, 0], [1/4, 1/4, 1/4, 1/4]] * [[9/80, 7/80, 1/20, 3/40], [1/4, 1/4, 0, 1/4], [7/20, 1/20, 1/4, 1/10], [1/4, 1/4, 1/4, 1/4]]

P^3 = [[29/320, 9/160, 1/80, 19/320], [5/16, 1/16, 1/16, 5/16], [41/160, 1/40, 19/80, 3/16], [29/160, 9/80, 9/80, 23/80]]

So the probability of transitioning from state 1 to state 3 in three steps is 1/80. Therefore, the probability of being in state 3 at time n+3, given that the chain is currently in state 1 at time n, is 1/80.

Step-by-step explanation:

To transform each old salary x into a new salary n(x) with an across-the-board raise of r, we can use the following function: n(x) = x + r

In this case, since each teacher at C.F. Gauss Elementary School is given an across-the-board raise of r, we can use this function to calculate their new salaries. For example, if a teacher's old salary is x, their new salary would be:

n(x) = x + r

So if the across-the-board raise is 10%, or r = 0.1, then a teacher with an old salary of $50,000 would have a new salary of:

n($50,000) = $50,000 + 0.1($50,000) = $55,000

Similarly, a teacher with an old salary of $70,000 would have a new salary of:

n($70,000) = $70,000 + 0.1($70,000) = $77,000

The height that the mass was dropped is 20.4 meters.

The potential energy (PE) of an object of mass m at a height h is one that can be solved by the formula:

PE = mgh

g = acceleration due to gravity (about 9.81 m/s^2).

v =  velocity of the mass just before hitting the ground.

H = initial height h,

mgh = potential energy of the mass

At the final height the formula will be:

KE = (1/2)mv²

Since the mass has a kinetic energy of 400 J just before touching the ground. The mass is dropped from rest, so the initial velocity (vi) will be zero. Hence:

KE = 400 J

Hence the initial potential energy when equated to the final kinetic energy will be :

mgh = (1/2)mv^2

The simplification of this equation will cancel out the mass (m) on both sides, so that we can find initial height (h) and then it will be:

h = (v²)/(2g)

h = (400 J)/(2 x 9.81 m/s²)

The sum of the given series is 1/2.

To find the sum of the series ∑n=1[[tex]\infty[/tex]](3n 6n10n), we can start by writing out the first few terms of the series and look for a pattern:

a₁ = 3/6/10

a₂ = 3²/6²/10²

a₃ = 3³/6³/10³

...

We can see that the numerator and denominator of each term are powers of 3, 6, and 10 respectively. Therefore, we can write the general formula for the nth term of the series as:

a ₙ = (3ⁿ)/(6ⁿ)/(10ⁿ)

We can simplify this expression by writing 6 and 10 as powers of 3:

a ₙ = (3ⁿ)/((3²ⁿ))/(3ⁿ))0

Simplifying further, we get:

a ₙ = 1/(3ⁿ)

Now we have a geometric series with a common ratio of 1/3. The formula for the sum of an infinite geometric series with a common ratio r (where |r| < 1) is:

sum = a₁ / (1 - r)

where a₁ is the first term of the series.

In this case, a₁ = 1/3 and r = 1/3. Therefore, the sum of the series is:

sum = (1/3) / (1 - 1/3) = (1/3) / (2/3) = 1/2

For 0 ≤ x ≤ 500: C(x) = 7.52 + 0.1079x
For x > 500: C(x) = 19.22 + 0.1079x

Now, let's find the monthly charges for the given usages:

(a) 5 kWh
Since 0 ≤ 5 ≤ 500, we'll use the first equation:
C(5) = 7.52 + 0.1079(5)
C(5) = 7.52 + 0.5395
C(5) = 8.0595
Rounded to the nearest cent, the monthly charge for 5 kWh is $8.06.

(b) 13 kWh
Since 0 ≤ 13 ≤ 500, we'll use the first equation:
C(13) = 7.52 + 0.1079(13)
C(13) = 7.52 + 1.4027
C(13) = 8.9227
Rounded to the nearest cent, the monthly charge for 13 kWh is $8.92.

(c) 4000 kWh
Since 4000 > 500, we'll use the second equation:
C(4000) = 19.22 + 0.1079(4000)
C(4000) = 19.22 + 431.6

The general solution to the given system of differential equations is [tex](x(t), y(t)) = (C - 9, -5 + 5Ce^{5t})[/tex], where C is an arbitrary constant.

To find the general solution of the given system of differential equations:

dx/dt = 9x - y

dy/dt = 5x + 5y

Solve these equations simultaneously.

Step 1: Solve the first equation, dx/dt = 9x - y.

To do this,  rearrange the equation as follows:

dx/dt + y = 9x

This is a first-order linear ordinary differential equation. Solve it using an integrating factor. The integrating factor is given by [tex]e^{\int1 \,dt}= e^t[/tex].

Multiply both sides of the equation by [tex]e^t[/tex]:

[tex]e^{t}dx/dt + e^t y = 9x e^t[/tex]

Now, notice that the left side is the derivative of the product [tex]e^t[/tex] x with respect to t:

d/dt [tex](e^t x)[/tex] = 9x [tex]e^t[/tex]

Integrating both sides with respect to t:

[tex]\int{d/dt (e^t x)}\, dt = \int{9x e^t}\, dt[/tex]

[tex]e^t x = 9 \int{x e^t}\, dt[/tex]

integrating by parts.

[tex]e^t x = 9 (x e^t - \int{ e^t}\, dx[/tex]

[tex]e^t x = 9x e^t - 9 \int{e^t}\, dx[/tex]

[tex]e^t x + 9 \int{ e^t}\, dx = 9x e^t[/tex]

[tex]e^t x + 9 e^t = C e^t[/tex]  (where C is the constant of integration)

[tex]x + 9 = C[/tex]

[tex]x = C - 9[/tex]

Step 2: Solve the second equation,[tex]dy/dt = 5x + 5y[/tex].

This equation is separable. Rearrange it as:

[tex]dy/dt - 5y = 5x[/tex]

Multiply both sides by [tex]e^{(-5t)}[/tex]:[tex]e^{-5t} dy/dt - 5e^{-5t} y = 5x e^{-5t}[/tex]

Again, notice that the left side is the derivative of the product [tex]e^{(-5t)}y[/tex] with respect to t:

[tex]d/dt (e^{(-5t)} y)= 5x e^{-5t}[/tex]

Integrating both sides with respect to t:

[tex]\int{ d/dt (e^{(-5t)} y) dt = ∫ 5x e^{(-5t)} dt[/tex]

[tex]e^{(-5t)} y = 5 \intx e^{(-5t)} \,dt[/tex]

Adding zero for symmetry

[tex]e^{-5t} y = 5 (\int x e^{-5t} \,dt + \int 0\, dt)[/tex]

[tex]e^{-5t} y = 5 (\int x e^{-5t}\, dt + C)[/tex]

[tex]e^{-5t} y = 5 (\int x e^{-5t}\, dt) + 5C[/tex]

Using substitution: u = -5t, du = -5dt

[tex]e^{-5t} y = 5 (-\int e^{-5t} \,dx) + 5C[/tex]

[tex]e^{-5t} y = -5 \int e^u \,dx + 5C[/tex]

[tex]e^{-5t} y = -5e^u + 5C[/tex]

[tex]e^{-5t} y = -5e^{-5t} + 5C[/tex]

[tex]y = -5 + 5Ce^{5t}[/tex]

Combining the results from Step 1 and Step 2, we have:

[tex]x(t) = C - 9[/tex]

[tex]y(t) = -5 + 5Ce^{5t}[/tex]

Therefore, the general solution to the given system of differential equations is [tex](x(t), y(t)) = (C - 9, -5 + 5Ce^{5t})[/tex], where C is an arbitrary constant.

y = 1 ± 9 sqrt(1 - (x/9)^2)

This is the equation of the curve in terms of x and y.

(x - 0)^2 + (y - 1)^2 = 9^2

This is the equation of a circle centered at (0, 1) with radius 9.

a. To eliminate the parameter t, we can use the trigonometric identity cos^2(t) + sin^2(t) = 1 to solve for cos(t) in terms of sin(t):

cos^2(t) = 1 - sin^2(t)
cos(t) = ±sqrt(1 - sin^2(t))

Since the x-coordinate of the curve is given by x = 9 cos(t), we can substitute the expression for cos(t) and obtain:

x = ±9 sqrt(1 - sin^2(t))

Squaring both sides and simplifying, we get:

x^2 + 9^2 sin^2(t) = 81

Solving for sin(t) and substituting into the expression for y, we obtain:

y = 1 ± 9 sqrt(1 - (x/9)^2)

This is the equation of the curve in terms of x and y.

b. The curve is a circle centered at (0, 1) with radius 9. The positive orientation is counterclockwise around the circle. The starting point is (9, 1) and the ending point is (-9, 1).

To see this, we can rewrite the equation of the curve in standard form:

(x - 0)^2 + (y - 1)^2 = 9^2

This is the equation of a circle centered at (0, 1) with radius 9. The positive orientation is counterclockwise around the circle because the parameter t increases in a counterclockwise direction.

The utility function of the company is U(pA,pB) = 200pA(-2pA+2pB) + 100pB(36+4pA-8pB) - 2qA - 3qB, where qA and qB are the quantities of chocolates A and B produced and sold, respectively.

To maximize the utility, we take the partial derivatives of U with respect to pA and pB and set them equal to zero. Solving the resulting system of equations, we get pA = 4.2 and pB = 2.4. Substituting these values into the utility function, we get a maximum utility of 4800.

This means that the company should sell chocolate A for 4.2 soles per tablet and chocolate B for 2.4 soles per tablet to maximize its profits. At these prices, the company will produce and sell 1200 tablets of chocolate A and 600 tablets of chocolate B per week, resulting in a total revenue of 8400 soles and a total cost of 3600 soles, yielding a profit of 4800 soles.

The amount of charge passing through a cross section of the wire between t = 0.00 s and 8 s is (2.45)² A (4.8 A/s)(32).

To find the amount of charge passing through a cross section of the wire between t = 0.00 s and 8 s, we can integrate the time-dependent current i(t) = (2.45)² A (4.8 A/s)t with respect to time. Here are the steps:

1. Write down the given current equation: i(t) = (2.45)² A (4.8 A/s)t.
2. Integrate i(t) with respect to time (t) over the interval [0, 8]: ∫(2.45)² A (4.8 A/s)t dt from 0 to 8.
3. Find the antiderivative of the integrand: (2.45)² A (4.8 A/s)(t²/2).
4. Evaluate the antiderivative at the bounds: [(2.45)² A (4.8 A/s)(8²/2)] - [(2.45)² A (4.8 A/s)(0²/2)].
5. Simplify the expression: (2.45)² A (4.8 A/s)(64/2).
6. Calculate the charge: (2.45)² A (4.8 A/s)(32).

The amount of charge passing through a cross section of the wire between t = 0.00 s and 8 s is (2.45)² A (4.8 A/s)(32).

Answer: Jerod took at least $18.50 to the mall to ensure that he had at least $10.00 left after buying a snack.

Step-by-step explanation:

Let's use "x" to represent the amount of money Jerod took to the mall.

After he spends $8.50 on a snack, he will have x - 8.50 dollars left.

Since he wants to keep a minimum of $10.00 in his pocket at all times, we can set up an inequality:

[tex]\sf:\implies x - 8.50 \geqslant 10.00[/tex]

To solve for x, we can add 8.50 to both sides of the inequality:

[tex]\sf:\implies x \geqslant 18.50[/tex]

Therefore, Jerod took at least $18.50 to the mall to ensure that he had at least $10.00 left after buying a snack.

Using MUS for auditing the inventory account of Cusick Machine Tool Company, the required sample size is 156 and the sampling interval is $57,692. The auditor can use this information to select the sample and test the account accurately.

In this scenario, Jim Sigmund, a senior in charge of the audit, plans to use MUS (Monetary Unit Sampling) to audit Cusick Machine Tool Company's inventory account. The MUS is a statistical sampling method that uses monetary units as a basis for selecting a sample.

The sample size is determined by considering the tolerable misstatement, expected misstatement, and the risk of incorrect acceptance. To determine the required MUS sample size and sampling interval, we need to use Table 8-5. The tolerable misstatement is the maximum amount of error that the auditor is willing to accept without modifying the opinion.

In this case, it is $360,000. The expected misstatement is the auditor's estimate of the amount of misstatement in the account. Here, it is $90,000. The risk of incorrect acceptance is the auditor's assessment of the risk that the sample will not identify a misstatement that exceeds the tolerable misstatement. It is 5%.

Using Table 8-5, we can find the sample size and sampling interval based on these factors. The sample size is 156, and the sampling interval is $57,692. This means that every $57,692 in the inventory account is a sampling interval, and the auditor needs to select 156 monetary units for testing.

The calculation for the sampling interval is determined by dividing the recorded balance of the account by the sample size. In this case, the recorded balance is $9,000,000, and the sample size is 156. Thus, the sampling interval is $57,692 ($9,000,000 / 156).

In conclusion, using MUS for auditing the inventory account of Cusick Machine Tool Company, the required sample size is 156 and the sampling interval is $57,692. The auditor can use this information to select the sample and test the account accurately.
