Answer:
94
Step-by-step explanation:
multiply the averages by their weighted percentage
x = final exam
88(.2) + 84(.2) + 92(.4) + x(.2) = 90
solve for x
x(.2) = 90 - 71.2 = 18.8
divide both sides by 0.2
x = 94
The mean of the number set is the average of the numbers
To find the average of the number set the numbers are to be added together and divided by the total amount of numbers in the set
P is at 0,-1
Q is at 2,-1
R is at 2, -2
S is at 0, -2
Divide the numerator into the denominator making it a mixed fraction
