Answer:

The test statistic is t = 3.36.

Step-by-step explanation:

You're testing the claim that the mean difference is greater than 0.7.

At the null hypothesis, we test if it is 0.7 or less, that is:

[tex]H_0: \mu \leq 0.7[/tex]

At the alternate hypothesis, we test if it is greater than 0.7, that is:

[tex]H_1: \mu > 0.7[/tex]

The test statistic is:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation and n is the size of the sample.

0.7 is tested at the null hypothesis:

This means that [tex]\mu = 0.7[/tex]

Survey of 35 people. From the sample, the mean difference was 0.95, with a standard deviation of 0.44.

This means that [tex]n = 35, X = 0.95, s = 0.44[/tex]

Calculate the test statistic

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{0.95 - 0.7}{\frac{0.44}{\sqrt{35}}}[/tex]

[tex]t = 3.36[/tex]

The test statistic is t = 3.36.

Answer:

B. Of the students who walk, the probability of choosing a female.

D. Of the females, the probability of choosing one who rides the bus.

Step-by-step explanation:

Conditional probability is the chance of something happening provided that something else has previously occured (think dependent events).

For example, the probability of getting into college P(college) is Event A.

The probability of receiving dormitory housing P(housing) is Event B.

First, the person must get into college before they are even able to receive dormitory housing. Therefore, this is a situation of conditional probability. The "condition" of being accepted into the college (Event A) is necessary before the individual can attempt Event B, housing.

The key word in the question is "Of all the students." This means that from the first instance, you are only calculating one probability.

However, in B, it first singles out "all the students who walk."

Therefore p(walk) must be met before p(gender) can happen.

Same with D, it singles out "of the females."

Therefore p(gender) must be met before p(transportation) can happen.

C does have two categories, but since it is still out of the general draw pool "of all students," it is not conditional. No condition needs to be met first to choose a male who walks out of ALL students.

Answer:

y does not vary directly with x

Step-by-step explanation:

The equation for direct variation is

y = kx ← k is the constant of variation

If k is constant for all ordered pairs in the table then direct variation.

k = [tex]\frac{y}{x}[/tex]

(2, 10 ) → k = [tex]\frac{10}{2}[/tex] = 5

(4, 24 ) → k = [tex]\frac{24}{4}[/tex] = 6

(6, 36 ) → k = [tex]\frac{36}{6}[/tex] = 6

Since k is not constant for all pairs then y does not vary directly with x

Answer:

He needs 15 shirts

Step-by-step explanation:

We can use a ratio to solve

4 pants             6 pants

--------------- = -------------

10 shirts            x shirts

Using cross products

4x = 10 *6

4x = 60

Divide each side by 4

4x/4 = 60/4

x = 15

He needs 15 shirts

Answer:

8.5

Step-by-step explanation:

slope of the line that contains KL

(y2 - y1)/(x2-x1)

(0-1)/(7-3)

m = -1/4

slope of the line that contains JK

(5-1)/(4-3)

m = 4

the linea are perpendicular so triangle is right

area = (leg1 x leg2)/2

KL = [tex]\sqrt{(7-3)^2 + (0-1)^2} = \sqrt{16 + 1} = \sqrt{17}[/tex]

KJ = [tex]\sqrt{(4-3)^2 + (5-1)^2}= \sqrt{1 + 16} = \sqrt{17}[/tex]

area = (√17)^2/2 = 17/2 = 8.5

Answer:

e. a civil right infringement lawsuit

Step-by-step explanation:

A civil right infringement lawsuit is a lawsuit filed by an offender whose civil rights have been violated by others. Civil rights are those rights of the citizens that is guaranteed by the Constitution of the United States to its people. They are right to equality, right to freedom, right to employment and all those rights that is included in the Bill of Rights of the US constitution.

Answer:

288 inches = 8 yards

Step-by-step explanation:

Answer:

[tex]6 . \: 8 \: yards \: = \: 288 \: inches[/tex]

[tex]8. \: 18 \: feets \: = \: 216 \: inches[/tex]

[tex]10. \: \frac{1}{3} \: yards \: = 12 \: inches[/tex]

Step-by-step explanation:

6. 1 yard = 36 inches

8 yards = 36 × 8

= 288

8. 1 feet = 12 inches

18 feets = 12 × 18

= 216 inches

10. 1/3 into decimal = 0.33333333333

1/3 yards = 0.33333333333 × 36

= 12 inches

Answer:

0

Step-by-step explanation:

Given that f(x) = 1/2x + 4

Let y = f(x)

y = 1/2 x + 4

Replace y with x

x = 1/2 y + 4

Make y the subject of the formula

1/2y = x - 4

y = 2(x-4)

If x = 3

y = 2(4-4)

y = 2(0)

y = 0

Hence ƒ -1(4) is 0

89.38

Step-by-step explanation:

65 times 0.25 = 16.25

16.25 plus 8.125 plus 65 = 89.38 dollars

Area of the figure is 88 square inches

Answer:

Lower bound for the length of the edge = 42.5 cm

Step-by-step explanation:

From the picture attached,

FH is the diagonal of square EFGH.

Therefore, length of diagonal FH = [tex]\sqrt{FG^2+HG^2}[/tex]

(By applying Pythagoras theorem)

In triangle AFH,

AH² = AF² + FH²

       = AF² + [tex](\sqrt{FG^2+HG^2})^2[/tex]

       = AF² + FG² + HG²

AH² = 3HG²

(11.3)² = 3(HG²)

HG = [tex]\sqrt{\frac{127.69}{3}}[/tex]

HG = 42.563 cm

For distance correct to the nearest mm, lower bound for the length of the edge = 42.5 cm

And upper bound for the length of the edge = 43.6 cm

The side lengths of a cu be are congruent, so the edge length of the cu be is 65 mm

The length of diagonal A H is given as:

[tex]\mathbf{AH = 11.3cm}[/tex]

Considering triangle A FH, we have:

[tex]\mathbf{AH^2 = A\ F^2 + FH^2}[/tex]

So, we have:

[tex]\mathbf{11.3^2 = A\ F^2 + FH^2}[/tex]

Considering triangle HE F, we have:

[tex]\mathbf{FH^2 = EF^2 + EH^2}[/tex]

Substitute [tex]\mathbf{FH^2 = EF^2 + EH^2}[/tex] in [tex]\mathbf{11.3^2 = A\ F^2 + FH^2}[/tex]

[tex]\mathbf{11.3^2 = A\ F^2 + EF^2 + EH^2}[/tex]

The side lengths of a cu be are congruent.

This means that: A F = EF = EH

So, we have:

[tex]\mathbf{11.3^2 = A\ F^2 + A\ F^2 + A\ F^2}[/tex]

Evaluate like terms

[tex]\mathbf{11.3^2 = 3A\ F^2}[/tex]

Evaluate squares

[tex]\mathbf{127.69 = 3A\ F^2}[/tex]

Divide both sides by 3

[tex]\mathbf{42.563= A\ F^2}[/tex]

Take square roots

[tex]\mathbf{6.52= A\ F}[/tex]

Rewrite as:

[tex]\mathbf{A\ F = 6.52cm}[/tex]

Convert to m m

[tex]\mathbf{A\ F = 6.52 \times 10mm}[/tex]

[tex]\mathbf{A\ F = 65.2\ mm}[/tex]

Approximate

[tex]\mathbf{A\ F = 65\ mm}[/tex]

Hence, the edge length is 65 mm
