Your friend comes from a large family. this list shows the ages of all of the children in his family. what is the median age of the children? 13, 6, 15, 7, 13, 10, 11

11

Step-by-step explanation:

The median is the middle value when all of the numbers are put in order from smallest to largest

6,  7,  10, 11,13,13,15

There are seven numbers so the middle number is 4

(3 on the left and 3 on the right)

The median is 11

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).

answer is 8 r5
