Protein bars come in a 4 pack box or a 12 pack box the 4 pack costs 7.68 and the 12 pack costs 22.32 which box is the better

Answer:

C) 0.1666

Step-by-step explanation:

The probability of selecting a calculator that is defective can be defined as: [tex]\frac{46}{46+26}[/tex]

The 46 in the numerator is the number of calculators that are defective in the group. The 46 + 26 represents the total amount of calculators since 46 are defective and 26 are not defective and assuming a calculator can only be defective or not defective then these are the total number of calculators in the group.

This gives you a probability of approximately: [tex]\frac{46}{72}[/tex] or approximately 0.638889

We can multiply independent events to find the combined probability of these events occurring. So we have to assume you put the calculator back into group after selecting one.

If this is the case we simply multiply 46/72 * 46/72 * 46/72 * 46/72 or (46/72)^4 to get an approximate probability of: 0.1666

The area of the pool given by the expression, ∆ × 102 + ∆ × 101 + 6, gives;

A) The whole number x = 33

B) The perfect square number closest to 33 is 36

The side length of a square pool with an area of 36 square units is 6 units

C) The side length of a square pool with the area chosen in part A is 33•√33

An expression is a mathematical statement which consists of 2 or more numbers and, or variables joined together by mathematical operators.

A) The given equations for the pool is presented as follows;

Area of the pool = ∆ × 102 + ∆ × 101 + 6

Area of the pool = x³

x = A whole number

Expressing the word problem mathematically gives;

∆ × 102 + ∆ × 101 + 6 = x³

203•∆ + 6 = x³

Which gives;

[tex] \displaystyle{ \triangle = \frac{ {x}^{3} - 6}{203} }[/tex]

Using a graphing calculator, when x = 33, we get;

[tex] \displaystyle{ \triangle = \frac{ {33}^{3} - 6}{203} = 177 }[/tex]

The value of the number is x = 33 and ∆ = 177

B) The perfect square that is closest to x = 33 is 36

The side length of a square pool with an area of 36 is √(36) = 6

C).The area of the pool chosen is 33³ = 35937

The side length of a square pool with an area of 35937 is √(35937) = 33•√(33)

The solution of B(x) = 18 - 0.5x with x being -2, 0, 5 is 19, 18 and 15.5.

Given:

B(x) = 18-0.5x

x = -2, 0, 5

Putting the values of x to find the result of the function.

B(-2) = 18 - 0.5 × (-2) = 18 + 1 = 19

The required solution of the function at x = -2 is f(-2) = 19.

B(0) = 18 - 0.5 × (0) = 18

The required solution of the function at x = 0 is f(0) = 18.

B(5) = 18 - 0.5 × (5) = 18 - 2.5 = 15.5

Thus, the required solution of the function at x = 5 is f(5) = 15.5.

The probability is 0.334 and the events are not disjoint​ events

The table of values represents the given parameters

The probability to calculate is given as

The probability of getting an order that is not accurate or is from Restaurant C

This can be represented as

P(Not accurate or Restaurant C)

This is calculated as

P(Not accurate or Restaurant C) = [n(Not accurate) + n(Restaurant C) - (Not accurate and Restaurant C)]/Total

So, we have

P(Not accurate or Restaurant C) = (37 + 52 + 34 + 19 +237 + 34 - 34)/(330 + 276 + 237 + 150 + 37 + 52 + 34 + 19)

Evaluate the sum and the difference

P(Not accurate or Restaurant C) = 379/1135

Evaluate the quotient

P(Not accurate or Restaurant C) = 0.334

Lastly, the events of selecting an order that is not accurate and selecting an order from Restaurant C are not disjoint​ events

This is so because it is possible to select an order from restaurant C that is not accurate

This necklace sold at auction for $11,379,600 in 2011. The percentage of the initial purchase price was represented by the auction price is 2.1%.

Given that,

For $54,000, an actor purchased a pearl, diamond, and ruby necklace for his well-known wife. This necklace sold at auction for $11,379,600 in 2011.

We have to find what percentage of the initial purchase price was represented by the auction price.

Let us take the percentage as x%.

Necklace sold at auction=the percentage multiplied by the actual price

We get,

$11,379,600 =x%($54,000)

x%=$11,379,600/$54,000

x%=2.1%

Therefore, the percentage of the initial purchase price was represented by the auction price is 2.1%.

The area of the parallelogram is 240 feet.

A parallelogram's area is the area that it occupies in a two-dimensional plane. A parallelogram is a four-sided, two-dimensional form in geometry. This particular quadrilateral example has equal and parallel opposite sides. The space bounded by a parallelogram's four sides is known as its area. A parallelogram's area is determined by multiplying its length by its height. 

A quadrilateral's interior angles add up to 360 degrees.

The area of a parallelogram can thus be written as :

Area = Base × Height

In this diagram it is given that the Base = 20 feet and the height = 12 feet

Thus the area can be obtained by simply multiplying these two dimensions

The value of f'(x) at x = 1 is 1 for first order derivative of x^x^3.

A derivative in calculus is the rate of change of a quantity y with respect to another quantity x. It is also termed the differential coefficient of y with respect to x. Differentiation is the process of finding the derivative of a function.

Given that, x^x^3 and we have to find the first order derivative with respect to x and then find the value at x = 1.

Let's proceed to solve this question accordingly.

let f(x) = x^x^3

The first order derivative = f'(x) = d/dx(x^x^3)

First apply the generalized power rule, then we have

= x^x^3.d/dx(ln(x)x^3)

Applying the power rule, we get

= x^x^3 (d/dx(x^3).ln(x)+x^3.d/dx(ln(x)))

= x^x^3 (3x^2 ln(x) +x^3.1/x)

= x^x^3 (3x^2ln(x) +x^2)

On simplifying, we will get

= x^x^3+2(3ln(x)+1)

f'(x) = d/dx(x^x^3) = x^x^3+2(3ln(x)+1)

Now, at x = 1, we get

f'(x) = d/dx(x^x^3) = x^x^3+2(3ln(x)+1) = 1

Therefore, f'(x) = d/dx(x^x^3) = x^x^3+2(3ln(x)+1) = 1 is the required answer.

According to the transitive property of equation, we have:

If A = B and B = C, then A = C

This can also be represented as

If A + B = C + D and C + D = E + F, then A  + B = E + F

M = ( (x₁+x₂)/2, (y₁+y₂)/2 )

Given the data in the question;

Point 1( 11, 3 )

Point 2( 4, 3 )

Midpoint = ?

To find the midpoint, plug the given points into the midpoint formula above and simplify.

M = ( (x₁+x₂)/2, (y₁+y₂)/2 )

M = ( ( 11 + 4 )/2, ( 3 + 3 )/2 )
