Acity has a population of 280,000 people. suppose that each year the population grows by 4.5% . what will the population be after 15 years?

Given that population of the city is 280000.

Rate of growth of the population = r = 4.5% = 0.045

We have to find population after 15 years so time

t = 15

We can use growth formula to find the required population which is given by :

Where P= starting population = 280000

r= rate of growth = 0.45

t= time = 15

now plug these values into above formula.

Hence population after 15 years will be approx 73735743.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
