The mean is 2.5. also there is mean, median, mode calculators online to help you with these in the future
Answer:
The probability that the person will not be a senior
P(E⁻) = 1 - P(E)
= 
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given A high school club has 10 members who are seniors and 8 members who are juniors
n(S) = 10 + 8 = 18
If a member is randomly selected to be the club president
Let 'E' be the event that the person will be a senior
The probability that the person will be a senior


The probability that the person will not be a senior
P(E⁻) = 1 - P(E)
= 
The formula would be:
<span>y = mx + b
</span><span>
Now, let's look at the information we know.
m = slope
b = y-intercept
y-intercept = -6
x-intercept = -2
</span>
First, we would need to determine the slope. The formula for slope is m =

Plug your coordinates in and solve it.

= 6/-2 = -3
Now, since we have the slope and y-intercept, we are ready to plug them into the formula.
y = -3x - 6I hope this helps!
