Find the volume of each rectangular prism

385

Step-by-step explanation:

L=Length

W=Width

H=Height

L=7

W=2

H=4

7 x 2 x 4

7 x 2 = 14

14 x 4 = 56

Rearranging to check my work:

7 x 4 x 2

7 x 4 = 28

28 x 2 = 56

I was right.

Hope this answers your question.

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.
