To simplify we need to rationalize it. which can be done by multiplying composite of denominator. That is multiply by -3-2i

Now multiply numerator with numerator and denominator with denominator







Hence final answer is 
Explanation:
When you perform long division of 50 by 7, you find that the quotient is 7 and the remainder is 1. The remainder expressed over the original divisor is the fraction. (In some cases, that fraction may need to be reduced.)
That is ...

The population is increasing at the rate of 220
Explanation:
Given that the population of Hannah's town is increased from 1500 to 2600 in five years.
This can be written in expression as
and

We need to determine the rate of change of population.
The rate of change can be determined using the formula,

where
and 
Substituting the values in the formula, we have,

Simplifying, we have,

Dividing, we get,
220
Thus, the population is increasing at the rate of 220
Mike tosses 70%
Ike tosses 67%
Both tosses 50%
<span>Which of the following is closest to the probability that Ike's proportion is ringers is higher than Mike's for those tosses?
</span>
P(m) = 70/100
P(i) = 67/100
P(b) = 50/100
= P(b) * P(i)
= 50/100 * 67/100
= 0.335
The correct answer is letter D) 0.3745.
