Answer:
Both and
are solutions to the system.
Step-by-step explanation:
In order to determine whether the two given points represent solutions to our system of equations, we must "plug" thos points into both equations and check that the equality remains valid.
Step 1: Plug into
The solution verifies the equation.
Step 2: Plug into
The solution verifies both equations. Therefore, is a solution to this system.
Now we must check if the second point is also valid.
Step 3: Plug into
Step 4: Plug into
The solution verifies both equations. Therefore, is another solution to this system.
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)
=
