Answer:

x = [tex]x = \frac{2+r}{p-8}[/tex]

Step-by-step explanation:

Move all terms to the left side and set equal to zero. Then set each factor equal to zero.

Answer:

(2+r)/(p-8) = x

Step-by-step explanation:

-px+r=-8x-2

Add px to each side

-px+r+px=-8x+px-2

r = -8x+px -2

Add 2 to each side

2+r = px-8x

Factor out an x

(2+r) = x(p-8)

Divide each side by (p-8)

(2+r)/(p-8) = x(p-8)/(p-8)

(2+r)/(p-8) = x

Answer:

$1,968.6

Step-by-step explanation:

Compound Interest = [P * (1 + i)ⁿ] - P

P = principal = $7,500

i = annual interest rate = 6%

n = number of periods = 4 years

Compound Interest = [$7,500 * (1 + 0.06)⁴] - $7,500

Compound Interest = [$7,500 * (1.06)⁴] - $7,500

Compound Interest = [$7,500 * (1.06)⁴] - $7,500

Compound Interest = [$7,500 * 1.26247696] - $7,500

Compound Interest = $9,468.5772 - $7,500

Compound Interest = $1,968.5772

Chairs for an orchestra are positioned in a curved form with the conductor at the center. The front row has 16 chairs, the second has 20 and the third has 24, and so on. describe the pattern of the sequence. How many chairs are in the 6th row?

Step-by-step explanation:

This scenario can be represented by an arithmetic progression sequence.

nth term of an AP = a + (n-1)d

Where;

a = first term

d = common difference

n = term number

Given;

First term a = 16

Second term = a + d = 20

since a = 16

a+d = 16+d = 20

d = 20-16 = 4

The sixth term;

= 16 + (6-1)4 = 16 +20 = 36

Sixth term = 36

Answer:

We reject the null hypothesis

Step-by-step explanation:

In statistical hypothesis testing, the p-value or probability value is the probability of obtaining test results at least as extreme as the results actually observed during the test, assuming that the null hypothesis is correct

Since the p value is less than a, you would reject the null hypothesis and conclude that women take more personal time than men.

Step-by-step explanation:

The equation of a parabola with Vertex (0, 0) and focus (0, 2) is,

y = 1/8x²

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The vertex of parabola = (0, 0)

And, The focus of parabola = (0, 2)

Hence, We get;

So, The equation of a parabola with Vertex (0, 0) and focus (0, 2) is,

x² = 4ay

x² = 4 × 2y

x² = 8y

y = 1/8x²

Thus, The equation of a parabola with Vertex (0, 0) and focus (0, 2) is,

Answer:

y = 1/28

Step-by-step explanation:

Given the expression:

½y - 21/4 = 35/4

We'll have to Multiply through with the LCM which is (2y * 4 = 8y)

(8y) ½y - (8y) 21/4 = (8y) 35/4

4 - 2y * 21 = 2y * 35

4 - 42y = 70y

4 = 70y + 42y

4 = 112y

Divide through by 112 to make y the subject.

y = 4 / 112

y = 1 / 28

Answer: y = 28

Step-by-step explanation:

Add both sides by 21/4 to cancel out the 21/4 on the left side. 1/2y = 56/4

You can rewrite the fraction 56/4 as 28/2 by dividing the numerator and denominator by 2. 1/2y = 28/2

Multiply both sides by 2 and you get y = 28

Answer:

168 cm³

Step-by-step explanation:

The base area of the oblique hexagonal prism = 42 cm²

the height of the prism = 4 cm

Volume of the prism = Base area × height = 42 cm² × 4 cm = 168 cm³

The volume of the oblique hexagonal prism is 260.00 cubic centimeters. This is calculated by multiplying the base area (65.00 square cm) by the height (4 cm) using the formula Volume = Base Area × Height.

To find the volume of an oblique hexagonal prism, you can use the formula:

Volume = Base Area × Height

You're given that the base area is 42 square cm and the height is 4 cm. Now, let's determine the base shape of the hexagonal prism.

A hexagon has six sides, and each side is an equilateral triangle with an edge length of 5 cm. To find the area of one of these equilateral triangles, you can use the formula:

Area of Equilateral Triangle = (side length^2 * √3) / 4

Area of Equilateral Triangle = (5 cm^2 * √3) / 4 ≈ 10.83 square cm

Since there are six identical triangles in the hexagonal base, the total base area is:

Base Area = 6 * Area of Equilateral Triangle ≈ 6 * 10.83 square cm ≈ 65.00 square cm

Now, you can calculate the volume:

Volume = Base Area × Height

Volume = 65.00 square cm × 4 cm = 260.00 cubic cm

So, the volume of the oblique hexagonal prism is 260.00 cubic centimeters.

Answer:

a) 0.65

b) 0.1581

Step-by-step explanation:

We are given the following in the question:

Distribution of X:

Mean = 0.125

Standard deviation = 0.05

Distribution of Y:

Mean = 0.350

Standard deviation = 0.10

Solution:

[tex]M = X + 1.5Y[/tex]

a) mean of M

[tex]\mu_M = \mu_X + 1.5(\mu_Y) = 0.125 + 1.5(0.350) = 0.65[/tex]

b) standard deviation of M

If X and Y are independent then,

[tex]Var(X+Y) = Var(X) + Var(Y)\\Var)aX) = a^2Var(X)[/tex]

[tex]Var(M) = Var(X+1.5Y)\\Var(M) =Var(X) + (1.5)^2Var(Y)\\Var(M) = (0.05)^2 + (1.5)^2(0.10)^2 = 0.025[/tex]

Standard deviation of M =

[tex]=\sqrt{Var(M)} = \sqrt{0.025} = 0.1581[/tex]

The mean of M is 0.650. The standard deviation of M is approximately 0.1581.

To find the mean of M, we need to substitute the mean values of X and Y into the equation M = X + 1.5Y. Given that X has a mean of 0.125 and Y has a mean of 0.350, we can calculate the mean of M as follows:

Therefore, the mean of M is 0.650.

To find the standard deviation of M, we can use the fact that X and Y are independent. The formula for the standard deviation of the sum of independent random variables is given by:

σM = √(σX2 + (1.5σY)2)

Given that X has a standard deviation of 0.05 and Y has a standard deviation of 0.10, we can substitute these values into the formula to calculate the standard deviation of M:

Therefore, the standard deviation of M is approximately 0.1581.

Answer:

The right question that describes what we need to examine is that:

If we examine the proportion of students at their campus who still live at home with their parents, how likely is that proportion to be more than 36%?

Step-by-step explanation:

For hypthesis testing, it is the p-value that needs to be obtained, to know the significance of the result. It is in the definition of what the p-value stands for that one would be able to pick which question best describes what we need to determine?

The p-value is actually defined as the probability of obtaining results as extreme as the observed results in the statistical analysis provided that the null hypothesis is true.

It is the probability of obtaining the claim to be tested that is usually contained in the alternative hypothesis, provided the null hypothesis is true.

So, since the null hypothesis states that the proportion of Millennial students at their campus, that live at home with their parents = 36%

The p-value is how likely it is or the probability that more than 36% of Millennial students at their campus live at home with their parents.

Final answer:

The solution set of the equation |–x| = 3.5 is found to be {3.5, -3.5}, considering both positive and negative values of x.

Explanation:

The solution set of |–x| = 3.5 involves considering two cases based on the absolute value:

When x is negative, the equation becomes -(-x) = 3.5, which simplifies to x = 3.5.

When x is positive, the equation remains -x = 3.5, resulting in x = -3.5.

Therefore, the solution set is {3.5, -3.5}.
