Randall invests $7200 in two different accounts. The first account paid 11 %, the second account paid 13 % in interest. At the end of the first year he had earned $832 in interest. How much was in each account?

Step-by-step explanation:

Let x represent the amount invested in the higher-earning account. Then the investment in the other account is (7200-x), and the total interest is ...

  0.13x +0.11(7200 -x) = 832

  0.02x = 832 -792 . . . . . . eliminate parentheses, collect terms, subtract 792

  x = 40/0.02 = 2000 . . . . divide by the coefficient of x

$2000 was invested at 13%; $5200 was invested at 11%.

11% -- $5200

13% -- $2000

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
