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%

Isolate the h. Do the opposite of the sign given - Because of equal sign, what you do to one side you do to the other
h/4 = 9
h/4(4) = 9(4)
h = 9(4)
h = 36
36 is your answer for "h"
hope this helps
In a triangle, the sum of the angles is equal to 180. This allows us to write an equation to find x.
x+3x+25+(x-5)=180
Simplify this to get
5x+20=180
Subtract 20 from both sides to get:
5x=160
Divide both sides by 5 to get that x=32
Now we can plug this into angle G to find its measure.
3(32)+25
=96+25
=121
So angle G is equal to 121 degrees.

Answer:
50
Step-by-step explanation:
if x years past she is twice her daughter's age,
so we get:
28+x=2(3+x)
x=22, 22+28=50
