Geometric mean between 9 and 36

nlexa [21]

I've actually just learned this. We would set up the proportion as X/9=36/X so after we cross multiply we get x^2=324. Then we find the square root of both sides to simplify. And using my calculator the square root of x^2 is just x. And the square root of 324 is 18. So the final answer is x=18 or the geometric mean is 18.

Answer:

0.86

Step-by-step explanation:

The z-score we need to make the comparison is given by

$\bf z=\frac{-2.05-(-2)}{\sigma/\sqrt{n}}$

where

$\bf \sigma$ = the standard deviation established in the study

n = the sample size

$\bf z=\frac{-2.05-(-2)}{0.3/\sqrt{42}}=-1.0801$

and for the Normal distribution N(0,1) we want to find

<em>P(X > -1.0801) </em>

By using a spreadsheet or the table attached, we find that

P(X > -1.0801) = 0.86

The sales of a particular brand of children’s athletic shoes rose from $6,900,000 to $7,400,000. Find the percent of increase in

Sidana [21]

Answer: 7.2%

Step-by-step explanation:

First find the difference between the amounts.

7,400, 000 - 6, 900,000 = 500, 000

Now divide the obtain number by the original number which is 6,900,000

500, 000/ 6,900,000 = 0.07246

Multiply 0.07246 by 100 to convert it to a percent.

0.07246 = 7.2463..%

Round it to the nearest tenth of a percent.

7.2463.. rounded to the nearest tenth is 7.2%

Answer:

$1.35

Step-by-step explanation:

8n = 10.80
