Express your answer in terms of pi.

C = 2 pi r, and r = 3ft, so C=2*pi*3 = 6pi ft.

**Answer:**

6π ft

**Step-by-step explanation:**

PA=3ft

Then just double it to get your answer.

B. -1

C. -2

D. 5

**Answer:**

1

**Step-by-step explanation:**

The y intercept is when x =0

We need to use the second equation

-x+1 since -2 < 0 <3

0+1

The y intercept is 1

**Answer:**

68% of the incomes lie between $36,400 and $38,000.

**Step-by-step explanation:**

We are **given the following** information in the question:

Mean, μ = $37,200

Standard Deviation, σ = $800

We are given that the distribution of SAT score is a bell shaped distribution that is a** normal distribution.**

**Empirical rule:**

- Almost all the data lies within three standard deviation of mean for a normally distributed data.
- About 68% of data lies within one standard deviation of mean.
- About 95% of data lies within two standard deviation of mean.
- About 99.7% of data lies within three standard deviation of mean.

Thus**, 68% of data lies within one standard deviation.**

**Thus, 68% of the incomes lie between $36,400 and $38,000.**

**Answer:**

99.72% probability that the proportion of Grammy award winners will differ from the singers proportion by less than 5%.

**Step-by-step explanation:**

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

**Normal probability distribution**

When the distribution is normal, we use the z-score formula.

In a set with mean and standard deviation , the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

**Central Limit Theorem**

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation .

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

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean and standard deviation

**In this question:**

So

**What is the probability that the proportion of Grammy award winners will differ from the singers proportion by less than 5%?**

This is the pvalue of Z when X = 0.41 + 0.05 = 0.46 subtracted by the pvalue of Z when X = 0.41 - 0.05 = 0.36. So

**X = 0.46**

By the Central Limit Theorem

has a pvalue of 0.9986

**X = 0.36**

has a pvalue of 0.0014

0.9986 - 0.0014 = 0.9972

99.72% probability that the proportion of Grammy award winners will differ from the singers proportion by less than 5%.
