A bird (B) is spotted flying 5,000 feet from a tree (T). An observer (0) spots the bird (B) at a distance of 13,000 feet. What is the angle of depression from the bird (B) to the observer (0)?

a- 22.70 degrees
b- 44.62 degrees
c- 67.38 degrees
d-68.96 degrees

a - base

b - exponent

so,

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.
