Step-by-step explanation:

We have been given that Connie is making a cardboard ice-cream truck for a school project. The truck is 8 inches long, 4 inches wide, and 6 inches tall. We are asked to find the amount of cardboard used by Connie to make the truck.

We will use surface area of cuboid to solve our given problem.

Upon substituting our given values in above formula, we will get:

Therefore, Connie needs 208 square inches of cardboard.

step-by-step explanation:

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.
