2. (10 points) the population of a city is 9,560. the population is growing at a rate of 2.5% annually.

a) use the exponential growth formula (y = a(1 + r)t) to write an equation that estimates the population in t years.

b) use your equation to estimate the population of the city in 20 years. (round to the nearest whole number. you must show your work to receive credit.

unless if u could do my questions, if not i wouldn't want to

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.
