The proof that δqpt ≅ δqrt is shown. given: sp ≅ sr prove: δqpt ≅ δqrt triangle p q r is shown. angle p q r is cut by a perpendicular bisector to form midpoint t on side p r. point s is on line q s. lines are drawn from points p and r to point s. line segments p s and s r are congruent.

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.
