# Write a function in terms of t that represents the situation.A population of 210,000 increases by 12.5% each yeary=

The exponential function is given by

### exponential function

An exponential function is in the form:

Where a is the initial value of y and b is the multiplier factor

Let y represent the population after t years.

Given an initial population of 210000, hence:

• a = 210000

The population increases by 12.5% each year, hence:

• b = 100% + 12.5% = 112.5% = 1.125

The exponential function is given by

Melissa collects data on her college graduating class. She finds out that of her classmates, 60% are brunettes, 20% have blue eyes, and 5% are brunettes that have blue eyes. What is the probability that one of Melissa's classmates will be a brunette or have blue eyes

The probability that one of Melissa's classmates will be a brunette or have blue eyes is 0.75.

### What is probability?

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

Here, given that,

60% are brunettes,

i.e. P(A)=0.6

20% have blue eyes,

i.e. P(B)=0.2

and 5% are brunettes that have blue eyes

i.e. P(A∪B)=0.05

So. P(A∩B)=  P(A)+P(B)-P(A∪B)

=0.6+0.2-0.05

=0.75

Hence, the probability that one of Melissa's classmates will be a brunette or have blue eyes is 0.75.
