5x3-x+ 9x7 +4 +3x11 decending order

denis-greek [22]

5x3-x+ 9x7 +4 +3x11

Answer:

115-X

Explanation:

First you multiply the 5x3

15-X+9x7+4+3x11

then the 9x7

15-X+63+4+3x11

then the 3x11

15-x+63+4+33

Now once you have completed the multiplication step you move on to calculating the sum. (Adding all the positive numbers)

15-x+64+4+33

115-x

Sonbull [250]

Answer:

The mean of the sampling distribution of p is 0.75 and the standard deviation is 0.0306.

Step-by-step explanation:

Central Limit Theorem:

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean $\mu = p$ and standard deviation $s = \sqrt{\frac{p(1-p)}{n}}$

75% of teenagers in North America are pursuing a goal they have set for themselves.

This means that $p = 0.75$

Sample of 200.

This means that $n = 200$ .

What are the mean and standard deviation of the sampling distribution of p?

By the Central Limit Theorem

Mean $\mu = p = 0.75$

Standard deviation $s = \sqrt{\frac{0.75*0.25}{200}} = 0.0306$

The mean of the sampling distribution of p is 0.75 and the standard deviation is 0.0306.
