Answer:

[tex]f(x)=9*\frac{5}{3}^x[/tex]

Step-by-step explanation:

When x equals 0, that means a is going to be multiplied by 1 since any number to the power of 0 is 1, so [tex]f(0)=a=9[/tex]. When x equals 1, that means that [tex]f(1) = 9b=15[/tex], so [tex]b=\frac{15}{9} =\frac{5}{3}[/tex]. This means that the equation should be [tex]f(x)=9*\frac{5}{3}^x[/tex].

[tex] F)\displaystyle \: 100\pi{ x}^{8} {y}^{2} {z}^{ 6} [/tex]

Step-by-step explanation:

we are given r and the formula

we want to find the surface area of the shpare with the given r

to do so

we need our algebra skills

substitute the value of r:

[tex] \displaystyle \: S = 4\pi( {5x}^{4} y {z}^{ 3} {)}^{2} [/tex]

recall law of exponent

[tex] \displaystyle \: ({x}^{m} {)}^{n} \iff \: {x}^{mn} [/tex]

to simplify:

[tex] \displaystyle \: S = 4\pi({ {5}^{2} x}^{4 \times 2} {y}^{1 \times 2} {z}^{ 3 \times 2} )[/tex]

simplify multiplication:

[tex] \displaystyle \: S = 4\pi({ 25x}^{8} {y}^{2} {z}^{ 6} )[/tex]

distribute:

[tex] \displaystyle \: S = 100\pi{ x}^{8} {y}^{2} {z}^{ 6} [/tex]

Simplify;

x/4-6<1/2

Add 6 to both sides;

Below is the Excel output from a study to see whether there is evidence of a difference in the mean amounts of time required to reach a customer service representative between two hotels. Assume that the population variances in the amount of time for the two hotels are not equal.
t-Test: Two-Sample Assuming Unequal Variances
Hotel 1 Hotel 2

Variance 2.951657 3.57855
Observations 20 20
Hypothesized Mean Difference 0

t Critical one-tail 1.685953
P(T<=t) two-tail 0.725009
t Critical two-tail 2.024394
A) State the null and alternative hypotheses for testing if there is evidence of a difference in the variabilities of the amount of time required to reach a customer service representative between the two hotels.
B) What is the value of the test statistic for testing if there is evidence of a difference in the variabilities of the amount of time required to reach a customer service representative between the two hotels? Explain how you obtain.
C) What is the critical value for testing if there is evidence of a difference in the variabilities of the amount of time required to reach a customer service representative between the two hotels at the 5% level of significance? Explain how you obtain.
D) Suppose α = 0.05. Which of the following represents the correct conclusion for a test on a difference in the variabilities of the amount of time required to reach a customer service representative between the two hotels?
1) There is no evidence of a difference in the variabilities of the amount of time required to reach a customer service representative between the two hotels.
2) There is evidence of a difference in the variabilities of the amount of time required to reach a customer service representative between the two hotels.

Answer:

A) H0: σ₁²-σ₂²= 0   against the claim  Ha: σ₁²-σ₂²≠0

B) t= 0.3543860

C)  t≥ t∝/2 ( d.f)=2.024394

D)1) There is no evidence of a difference in the variability of the amount of time required to reach a customer service representative between the two hotels.

Step-by-step explanation:

The claim is that there is evidence of a difference in the variability of the amount of time required to reach a customer service representative between the two hotels which is the

alternate hypothesis

The null hypothesis is the reverse of the alternate hypothesis

The null hypothesis is that there is not enough evidence of a difference in the variability of the amount of time required to reach a customer service representative between the two hotels.

Part A) H0: σ₁²-σ₂²= 0   against the claim  Ha: σ₁²-σ₂²≠0

Part B) t= x1`-x2`/ sqrt ( s₁²/n₁ + s₂²/n₂)

  t=  2.214- 2.0115/ sqrt ( 2.951657/20+  3.57855/20)

 t= 0.2025/ sqrt(0.14758285 + 0.1789275)

t= 0.2025/0.5714108

t= 0.3543860

Part C) for 2 tailed test the critical value of t is obtained by

t≥ t∝/2 ( d.f)= ± 2.024394

We look at the table with values 0.025 as ∝/2= 0.05/2= 0.025

in the degrees of freedom 38

The d.f = n1+n2-2= 20+20-2= 40-2= 38

Part D) Since the calculated value of t= 0.3543860 does not fall in the critical region  t≥ t∝/2 ( d.f)= ± 2.024394 we conclude that H0 is true and accept the null hypothesis.

So option 1 is correct

1) There is no evidence of a difference in the variability of the amount of time required to reach a customer service representative between the two hotels.

During a baskethall game, you want to pass the ball to either Player A or Player B. You estimate that Player B is about 15 feet from you, as shown. How far away from you is Player A?

Answers

Answer: 19.2 ft

Step-by-step explanation:

The distance between you, Player A and Player B are in the form of a right angled triangle so using the Pythagorean Rule, we can find the distance between you and Player A.

c² = a² + b²

c = hypotenuse = Distance between you and player A

a = Length of triangle

b = Height of triangle

c² = 12² + 15²

c² = 144 + 225

c = √369

c = 19.2 ft

Whether it is a partial or a total eclipse or not, seeing the shadow of the Moon cover some or all of the Sun's surface in the middle of the day can be quite dramatic! Eclipses happen when the Moon comes between the Earth and the Sun, blocking some of the Sun's light. If you look online, you can find some impressive eclipse photos taken by professional and amateur photographers. On average, solar eclipses happen twice a year. Some of these photos have been touched up, or improved, using computer software, but others are completely real.Paragraph 2 When the time gets closer, you will need to prepare for viewing a solar eclipse! A solar eclipse can be visible in different parts of the world; however, you have to take some safety measures when viewing one. Fortunately, there are a number of perfectly safe ways to view such an amazing event. You cannot simply look up at the sun, or you will ruin your eyes in a matter of moments. If the idea of watching a solar eclipse appeals to you, check various astronomy Web sites to find out when the next one will be occurring.Paragraph 3 A special material makes them safe for viewing the Sun. One safe way to view eclipses is with "eclipse glasses." The frames of the glasses are made of cardboard, and the lenses are made of special material that blocks out all but a tiny bit of light. These are available by mail order from telescope shops and are also sold by science museums. Eclipse glasses do not cost more than a dollar or two a pair. However, make sure to order them at least a month ahead of time because they tend to sell out in the days before the event.Paragraph 4 Another safe way to view the solar eclipse is to make a viewer yourself! The easiest kind is a pinhole viewer. You can try this out on any sunny day. Just get two pieces of white cardboard, about the size of a sheet of printer paper. Make a tiny pinhole in the center of one piece. Then hold it in the sunlight so the sun shines through the hole, and hold the other piece of board underneath. After a few attempts, you should be able to line up the Sun's image so it projects onto the second piece of white board. If you move the cardboard with the pinhole farther away from the bottom cardboard, the image will be bigger. Now, you can view a solar eclipse easily, and protect your precious eyesight!Which paragraph is organized in the most logical order?A. paragraph 1 B. paragraph 3 C. paragraph 4 D. paragraph 2
