You are told the ages of Karen and David in terms of Michelle's age.
Let m = Michelle's age.
Michelle's age = m
Karen's age = m + 6
Michelle is two years younger than David, so David is two years older than Michelle.
David's age = m + 2
Add the ages and get 62.
m + m + 6 + m + 2 = 62
3m + 8 = 62
3m = 54
m = 18
Michelle is 18 years old
Karen is 6 years older, so she is 24 years old.
David is 2 years older than Michelle, so he is 20 years old.
This count is a discrete random variable (option A).
<h3>What is a
discrete random variable?</h3>
A discrete random variable is a variable that contains integers that can only be a limited number of possible values. A discrete random variable is can contain only a finite set of numbers .
An example of discrete random variable is the number of students in the first period class. It is impossible for the number of students in the class to go on indefinitely.
Discrete random variable has the following properties:
- It is finite
- It is numeric
- It is countable
- It contains non-negative integers.
A continous random variable is a variable that has an infinite number.

#SPJ1
Answer:
BD
Because it is straight line segment that passes through center from one point in circumference to other
So the answer to this question is:
A= bees: f(t) = 1500 × (0.88)∧t
plants: g(t) = 800 - 25×t
B: (Bees) 1500 × (0.88)∧6= 696.60
After 6 months (696 bees ):
800 - 25×6 = 650 (Flowering Plants)
After 6 months:
650 flowering plants
C: 1500 × (0.88)∧t=800 - 25×t
t = 6.779965672
Answer is it will take 7 months or 6 for the bees and the plants.
Hope this helps!
