The binomial formula with the given parameters has a value of 0.0272

The given parameters are

N = 65

p = 0.5

X = 39

The interpretation of the above parameters are

Sample size, N = 65

Probability of success, p = 0.5

Number of success, X = 39

The binomial probability states that

P(x) = ⁿCₓ * pˣ * (1 - p)ⁿ⁻ˣ

Where n, p and x are the same as the parameters described above

When the values are substituted in the binomial probability formula, we have

P(39) = ⁶⁵C₃₉ * (0.5)³⁹ * (1 - 0.5)⁶⁵⁻³⁹

Evaluate the difference

P(39) = ⁶⁵C₃₉ * (0.5)³⁹ * (0.5)²⁶

Evaluate the products

P(39) = ⁶⁵C₃₉ * (0.5)⁶⁵

This gives

P(39) = 0.0272

Hence, the value of the binomial formula is 0.0272

Car B travelled with the rate of speed of 40mph .

In the question ,

it is given that ,

Car B travelled 5mph slower than Car A .

let the rate of speed at which Car B travelled be x mph.

So , the rate of speed of Car A is = (x+5) mph

Car A travelled the distance in 4 h , with the speed of (x+5) mph ,

the value of T = 4 h and R = (x+5) mph

So, by the formula R*T=D ,

we get ,the distance travelled by Car A = 4(x+5) miles .

Car B travelled the distance in 4.5 h , with the speed of x mph .

the value of T= 4.5h  and R = x mph

So, by the formula R*T=D,

we get , the distance travelled by Car B = 4.5*x = (4.5x) miles .

Since , both the cars travelled the equal distance ,

we get ,

4(x+5) = 4.5x

4x+20=4.5x

4.5x-4x = 20

0.5x= 20

x = 40

Therefore , the rate of speed of Car B is 40 mph.

The $7,000 worth of purchase and payment of $5,000 before the three months deadline gives the amount owed at 2.49% monthly compound interest rate as $2,153.15

Owed: $2,153.15

Compound interest accounts for the interest that is earned on an interest, such that the interest rate is compounded on an initial amount.

The given parameters are;

The amount of the items purchased from the store = $7,000

The amount of down payment required = 10%

The amount paid in three months = $5,000

Monthly interest on amount owed after three months = 2.49%

Required;

The amount owed after payment of $5,000 before three months

Solution;

Using the compound interest formula, we have;

[tex] \displaystyle{A = P \cdot \left(1 + r \right)^{n} }[/tex]

Where;

A = The amount owed

P = The amount loaned = $7,000 - $5,000 = $2,000

r = Monthly interest rate = 2.49%

n = The number of months = 3 months

Which gives;

[tex] \displaystyle{A = 2000 \times \left(1 + 0.0249 \right)^{3} \approx 2153.1509}[/tex]

The Standard form is y = [tex]x^{2}[/tex] + 6x - 16

Given,

A quadratic function n standard form whose graph has the given characteristics.

and, passes through (-8, 0), (-6, -16), (2,0).

To find the y =?

Now, According to the question:

Because the graph of a quadratic goes through point (-8 ,0) and point   (2, 0)

So, supposing the equation of the quadratic function is  

y = a [x - (-8)] (x - 2) = a (x + 8)(x - 2)

The graph passes through the point (-6, 16)

So, -16 = a(-6 + 8)(-6 -2)

=> -16 = a x 2 x (-8)

=> a = 1

So, y = (x + 18)(x - 2)

y = [tex]x^{2}[/tex] + 8x - 2x - 16

y = [tex]x^{2}[/tex] + 6x - 16

The volume that the shipping box which measure 36 inches by 24 inches by 18 inches can hold is 9 cubic feet.

A rectangular prism is simply a three-dimensional solid shape which has six faces that are rectangles.

The volume of a rectangular prism is expressed as;

V = w × h × l

Given the data in the question;

Plug the given values into the formula above and solve for the volume V.

V = w × h × l

V = 2ft × 1.5ft × 3ft

V = 3ft² × 3ft

Volume V = 9ft³

Therefore, the volume of the rectangular prism is 9 cubic feet.

SOLUTION:

Step 1:

In this question, we are given the following:

Use geometry to evaluate:

Step 2:

The details of the solution are as follows:

CONCLUSION:

The final answer is:

Variable x would be easier to solve for.

Step - by - Step Explanation

What to find?

• The value of x.

• The value of y.

• The variable that was easier to solve.

Given:

5x+3y=22

4x-2y=16

Using elimination method,

First solve for x.

To solve for x, multiply through the first equation by 2 and then multiply through the second equation by 3.

10x + 6y = 44 _____________(3)

12x - 6y = 48 ______________(4)

Add (3) and (4)

22x = 92

Divide both-side of the equation by 22

x = 92/22

Reduce the fraction by 2.

x =46 / 11

To solve for y,

Multiply through the first equation by 4 and through the second equation by 5.

20x + 12y = 88 _________________ (5)

20x - 10y = 80 __________________(6)

Subtract equation 6 from 5.

22y= 8

Divide both-side of the equation by 22.

y = 8/22

We can reduce the fraction by 2.

y = 4 / 11

Judging from the steps above, we can deduce that the variable that was easier to solve is x.

Answer: x  of first equation

Step-by-step explanation:

By solving both equations we get x =:

1. x = 12

2. x = 28/3

1. |x - 3| = 2x - 15

|x - 3| - 2x = 2x - 15 - 2x

by simplifying,

- 2x + |x - 3| = -15

- 2x + x -3 = -15  and -2x - (x - 3) = -15

by solving equation ,

= -x -3 = - 15

= -x = -12

x = 12

2. 8 - 2|6 - x|= 20

6 |6 - x| = 20

6 |-x + 6| = 20

dividing both side with 6,

(6 |-x + 6|)/6 = 20/6

| -x + 6| = 10/3

add 6 on both sides,

x - 6 + 6 = 10/3 +6

x = 28/3

The common ratio is 3.

The index of the 13th term of the sequence is n = 13.

The sum of n terms of a geometric sequence with first term a1 and common ratio r is ...

Congruent polygons are those that have equal measurements. Since we are given their graphs, we simply inspect each pair of polygons to determine which among them are congruent.

I have made an example using the first pair. I rotated the first polygon (the red one) to show that they are indeed congruent.

Following the same process, we can see that pairs 3 and 4 are also congruent.

Pair 2 are not congruent because the green rectangleis longer.

So the answer is pairs 1, 3, and 4.

The measure of angle p is 213 degrees

The possible question is added at the end of the solution and as an attachment

From the attached figure, we have the following angles

Also, from the attached figure:

We can see that the three angles named above are formed by lines that meet at a point (say the point of origin)

When multiple lines meet at a point, the sum of the angles formed at this point is 360 degrees

This means that

Angle 1 + Angle 2 + Angle 3 = 360

Substitute the known values in the above equation

So, we have

p + 57 + 90 = 360

Evaluate the sum in the above equation

So, we have

p + 147 = 360

The resulting exponent form is, 1/9¹⁰

Exponent:

Exponent is used to show repeated multiplication of a number by itself. For example,

7 × 7 × 7 can be represented as 7³

Here, the exponent is ‘3’ which stands for the number of times the number 7 is multiplied.

Given,

Here we have the exponent form is,

9⁻⁸x9⁻²

Here we have to use the product property and then we have to get rid of negative exponents.

First step is to use the product property,

We know that, the product property states that,

for any non-zero term a,

yᵃ x yᵇ = yᵃ⁺ᵇ

where a and b are real numbers.

So, the given expression is written as,

=> 9⁻⁸⁺⁽⁻²⁾

=> 9⁻⁸⁻²

=> 9⁻¹⁰

Now the second step is to get rid of the negative components,

As per the rule, the exponent is negative, we can change the exponent into positive by writing the same value in the denominator and the numerator holds the value 1.

So, the value is,
