  A, D, E

Step-by-step explanation:

Assuming your graph is of the equation ...

  y = 3/4x -1

The slope is 3/4. The line intersects (0, -1). The y-intercept is -1.

  A, D, E are true

answer: i believe it’s 245.04

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.
