Answer:

Graph A

Step-by-step explanation:

A = y = 1.5 x = -2\<x,< 3

B = y = 0.2 x = -2<x < 2

C = y = -1.2 x = -2< x\< 3

D = y = 1.2 x = - 2< x < 2

Charra [1.4K]

Answer:

lets say they share the cost in 5 parts, because Anna will distribute 4 time as much as Emily.

120 / 5 = 24

Emily: $24 (1/5 of 120)

Anna: $24 * 4 = $96 (4/5 of 120)

If triangle RST and triangle XYZ are similar, which of these equations must be true?

Delicious77 [7]

Answer: A

Step-by-step explanation:

If they are similar, that means the proportions for corresponding sides will be the same.

I personally ignore the picture and use the labels of "triangle RST and triangle XYZ" that the problem gives because the XYZ picture is not lined up with the similarity it has with RST.

(A) says that side ST is corresponding with side YZ,

[] Triangle RST and triangle XYZ

-> Correct

(A) also says that side RT is corresponding with size XZ,

[] Triangle RST and triangle XYZ

-> Correct

This means that option A is the correct answer.

ozzi

Answer:

By the Central Limit Theorem, the best point estimate for the average number of credit hours per semester for all students at the local college is 14.8.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Mean of the sample:

14.8 credit hours per semester.

By the Central Limit Theorem, the best point estimate for the average number of credit hours per semester for all students at the local college is 14.8.
