585 cubic inches

292.5 square inches

585 square inches

Find the area of the triangle, then multiply by the depth of the prism:

Area of a triangle = 1/2 x base x height = 1/2 x 15 x 3 = 22.5 square inches.

Volume = 22.5 x 13 = 292.5 cubic inches.

stops on an even number.

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.
