a. tq
b. pr
c. ra
d. qp
e. ej

QP, EJ , QT are perpendicular to QE.

Step-by-step explanation:

Given  : The figure shown is a rectangular prism.

To find : Which edges are perpendicular QE.

Solution : We have given a rectangular prism.

Perpendicular line : A line is said to be perpendicular to another line if the two lines intersect at a right angle.

We can see there are three line fall on QE .

The line QP is perpendicular to QE.

Line EJ is perpendicular to QE.

Line TQ is also perpendicular on QE.

Therefore, QP, EJ , QT are perpendicular to QE.

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.
