The sum of your data set is 23.8333333333.All you have to do is add them all together and then divide by 6, which is the number of numbers there are.
8+13+17+26+32+47=143
143/6+23.8333333333
Answer:
5 months
Step-by-step explanation:
Let the number of months equalising both plans fee = x
Plan A total fee = 75 + 15x , Plan B total fee = 20 + 26x
Equalise both: 75+15x = 20+26x ; 75-20 = 26x-15x ; 55 = 11x ; x = 55 / 11
x = 5
Proof : 75 + 15 (5) = 20 + 26 (5) ; LHS 150 = RHS 150
ik=30.5 because 49 - 12 = 37.5 and 37.5/2+12=30.5
Answer:
X=5
Step-by-step explanation:
You want to factor the left side of the equation
(X-5)(x-5)=0
Set factors that will equal to 0
X-5=0
X=5 is the answer
