<span>The answer should be 14t - 2m2 - 5/2 , if I am correct</span>
I do not see a picture sadly.
Answer:
3x
Step-by-step explanation:
The area of a triangle is (base × height)/2.
In this picture, the base is 3.
The height is 2x.
(3×2x)/2
=6x/2
=3x
The probability that a randomly selected male college student gains 15 lb or more during their freshman year is 11.6%
<h3>What is Probability ?</h3>
Probability is defined as the likeliness of an event to happen.
Let X be a random variable that shows the term "freshman 15" that claims that students typically gain 15lb during their freshman year at college.
It is given that
X follows is a normal distribution with a mean of 2.1 lb (μ) and a standard deviation (σ) of 10.8 lb.
Population Mean (μ) = 2.1
Population Standard Deviation (σ) = 10.8
We need to compute Pr(X≥15). The corresponding z-value needed to be computed is:

Then the probability is given as

Pr(X≥15)=0.1162. (11.6%)
The probability that a randomly selected male college student gains 15 lb or more during their freshman year is 11.6%
