Thanks in advance people.

Dvinal [7]

Answer:

The answer is 64.

Step-by-step explanation:

Lets say the top row is x and the bottom row is y.

Since when x is 13 y is 104 and when x is 14 y is 112 that means the y value goes up by 8 every time.

when x=3: 16+8=24

when x=4: 24+8=32

when x=5: 32+8=40

when x=6: 40+8=48

when x=7: 48+8=56

when x=8: 56+8=64

Hope this helps you!!!!

Tre has to pay $180 to book the recording studio plus $30 per hour of recording time. The function c(h)=30h+180 relates the tota

blagie [28]

Answer:

1. $330
2. 11.5 hours

Step-by-step explanation:

Continuation of the question:

1. Find c (5) and interpret your solution in the context of the problem
2. Find the value of h when c() = 525 and interpret your solution in the context of the problem

Solution

c(h) = 30h + 180

1 ...............................................

c(5) = 30*5 + 180 = $330

2 ...............................................

525 = 30h + 180
30h = 525 - 180
30h = 345
h = 345/30
h = 11.5 hours

You have a square(40 inches by 24 inches) and reduce it to create the smaller box of 10 inches by 6 inches. What is the scale fa

Gnoma [55]

Answer:

4 inches

Step-by-step explanation:

40/24=10/6

40/10=4

24/6=4

(40/24)/(4/4)=10/6

(10/6)(4/4)=10/24

g You are planning an opinion study and are considering taking an SRS of either 200 or 600 people. Explain how the sampling dist

Katen [24]

Answer:

By the Central Limit Theorem, both would be approximately normal and have the same mean. The difference is in the standard deviation, since as the sample size increases, the standard deviation decreases. So the SRS of 600 would have a smaller standard deviation than the SRS of 200.

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.

For the sampling distribution of size n of a sample proportion p, the mean is p and the standard deviation is $s = \sqrt{\frac{p(1-p)}{n}}$

Differences between SRS of 200 and of 600

By the Central Limit Theorem, both would be approximately normal and have the same mean. The difference is in the standard deviation, since as the sample size increases, the standard deviation decreases. So the SRS of 600 would have a smaller standard deviation than the SRS of 200.
