For this case we have the following division:

$\frac{6.28 * 10 ^ {12}}{3.14 * 10 ^ 4}$

Rewriting the product we have:

$(\frac{6.28}{3.14}) (\frac{10^{12}}{10^4})$

By definition we have to:

In the divison, if we have the same base we subtract the exponents.

We have then:

$(2) (10 ^ {(12-4)})\\(2) (10 ^ 8)$

Answer:

The exponent of 10 in the division will be:

The English phrase of the obtained equation is 12 times z subtracted by 3. The obtained equation after solving is 12z -23

<h3>What exactly is simplification?</h3>

Simplifying means making something easier to do or comprehend, as well as making something less difficult.

Given data;

z be the unknown number

Given conditions;

1. The difference between a number and −23.

2.−23 is equal to the product of the number and 13.

The mathematical form of the given phrase is;

⇒ z - (-23) = z × 13

⇒z+23 = 13z

⇒12z -23

The English phrase of the obtained equation is 12 times z subtracted by 3.

Hence the simplification of the given expressions is 12z -23.

At Appalachian State University it is known that 52% of undergraduates are female. If a sample of 150 undergraduate students was

In-s [12.5K]

Answer:

a. The sampling distribution will be approximately normal.

d. The mean of the sampling distribution will be close to 52%

g. The standard deviation of the sampling distribution will be 0.0408

Step-by-step explanation:

For this problem the sample size is large enough (n>30), and then the sampling distribution $\hat p$ would be approximately normal. The mean of the sampling distributions is given by $p=0.52$

The expected value for the sampling distribution would be 0.52 since $E(\hat p) = p$

And for the standard deviation we know that is given by:

$Sd= \sqrt{\frac{p (1-p)}{n}}=\sqrt{\frac{0.52(1-0.52)}{150}}=0.0408$

So the correct answers on this case are:

a. The sampling distribution will be approximately normal.

d. The mean of the sampling distribution will be close to 52%

g. The standard deviation of the sampling distribution will be 0.0408
