Two scientists are running experiments on the same type of bacteria in different control groups. The results are shown in the graph using the functions fod and go
Which statement best describes the graph of fb) and 900?
The graph of fb) will eventually exceed the graph of 900.
The graph of gb will eventually exceed the graph of fo.
The graphs will both have their y-intercept equal to -1.
The graphs will both have their y-Intercept equal to 8.

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.
