Triangle END is reflected across the line y= x using the rule (x, y) (y, c) to create triangle E'N'D'. If a line segment is drawn from point E to point E', which statement best describes the line segment drawn in relation to the line y = x? Both are congruent to each other.

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.
