Elise built a rectangular vegetable garden that is 9 feet long and has an area of 72 square feet. what is the perimeter of elise’s vegetable garden?

We have to find the width first.

72 divide by 9 = 8

To find the perimeter, you can do it two ways:

1. 9 + 8 + 9 + 8 = 34

2. 2(9) + 2(8) = 18 + 16 = 34

The answer is 34 feet.

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
