Answer:
A) discrete random variable.
Explanation:
Discrete random variables can assume only a finite number of values, and their combined total probabilities must equal 1.
On the other hand, continuous random variables can take any value with an interval or collection of intervals, which means that the possible values are infinite.
A complex random variable is a combination of two real random variables that have rel and imaginary parts.

Answer:
Option (A) is correct.
Explanation:
Given that,
Estimated fixed cost = $288,000
Estimated variable cost = $14 per unit
Units expects to produce and sell = 60,000
Selling price = $20 per unit
We first need to calculate the contribution margin:
Contribution margin per unit:
= Selling price - Variable cost
= $20 - $14
= $6
The break even point in units is the ratio of fixed cost to the contribution margin per unit.
Break-even point in units:
= Fixed cost ÷ Contribution margin per unit
= $288,000 ÷ $6
= 48,000 units
Mike brought 100 shares costing $53 each.
Total costs of shares= 100*53
=$5300
He got dividends of $1.45 per share. A dividend is money that is earnt back from a share.
Total dividend amount = 1.45*100
=$145
I'm assuming that Mike sold his shares at the end of the year. He sells for $60 each.
Total sales amount=60*100
=$6000
The rate of return in this instance can be defined as the amount of money made back from a share.
Rate of return= total earnings/ costs
Total costs= $5300
Total earnings=$6145
6145/5300=1.1594
=15.9%
Hope this helps! :)
