Suppose that when your friend was born, your friend's parents deposited $8000 in an account paying 4.9% interest compounded quarterly. What will the account balance be after 13 years?

$15,010.70

Step-by-step explanation:

i think I'm not completely sure because I don't know how much they're going to pay their son per month if they pay him

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

thats not a system of equations, that is a solution
