4) the cost of membership at local country club is $125 per family member per month. each family also has to pay $75 in service fees. model the cost, c, for a membership for a family with x members. a) c(x) = 75x b) c(x) = 125x c) c(x) = 125x + 75 d) c(x) = 125 + 75x

C) C(x) = 125x + 75

Step-by-step explanation:

The membership of the local country club costs $125 per family member, since don't know the exact number of members, we will put an x next to 125 to describe per.  The $125 cost increases as x increases.  Each family, no matter what, has to pay 75 dollars, so we don't have to put a variable next to it because it is guaranteed.  

51-50

step-by-step explanation:

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
