A rectangular flowerbed at a city park has an area of 126 square meters.the width of the flowerbed is 3 meters.what is the perim

Alona [7]

First we need to find the length. So we do 126/3 to get 42. The length is 42. Now to find perimeter we do 2(42)+2(3) or 42+42+3+3.

Both ways are right ways. The perimeter is 90 meters.

Hope that helps!!

What is the solution to 11 = x – 4?

marishachu [46]

Well to find out X, you have to do the opposite to what it's asking to each side. So 11=x-4

+4 onto the 11 and + 4 on to the -4 which means you just have 15=X

Answer:

No, this result is not surprising. It is a little bit more than one standard deviation above 20%

Step-by-step explanation:

Proportion of each color in the population (p) = 0.20

Sample size (n) = 20 Skittles

The standard deviation of a sampling distribution is determined by:

$\sigma = \sqrt{\frac{p*(1-p)}{n}}\\\sigma = \sqrt{\frac{0.20*(1-0.20)}{20}}\\ \sigma =0.089$

The difference between the observed proportion of 0.30, and the mean proportion of 0.20 is 0.10, which is just a little bit more than one standard deviation of 0.089. Therefore, this result is not surprising since it is a little bit more than one standard deviation above 20%.
