The manager will put 6 parakeets each in 7 cages and 6 canaries each in 3 cages.

Step-by-step explanation:

We will find the greatest common factor of 42 and 18 to know the answer.

42 = 2 x 3 x 7

18 = 2 x 3 x 3

So, greatest common factor is

So, 42 parakeets need cages

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.
