Answer:

1.7

Step-by-step explanation:

Verified correct in a K12 test, but I looked up how to do it... A calculator is the easiest way!!  :o

From mathisfun website:

  • Work out the Mean (the simple average of the numbers)
  • Then for each number: subtract the Mean and square the result.
  • Then work out the mean of those squared differences.
  • Take the square root of that and we are done!

Komok [63]

Answer:

Part A: $55.50

Part B: 52 hamburgers(sorry if I am wrong for part b but I think it is right)

Step-by-step explanation:

Part A:     $14.50 x 3= $43.50  +         24 x $0.50= $12=        

 ($ earned per hrs  x hrs worked)+  ($ per hamburger sold x times amount)

Hence $43.50 + $12= $55.50.

Part B:        $14.50 x 6.5 = $94.25                           $120 - $94.25= $25.75

 ($ earned per hrs  x hrs worked x x hrs worked)   ($ earned - $ earn from shif

 $25.75/0.50=51.5 (51.5 rounded to nearest burgers is 52 burgers)

Hence answer is 52 burgers.
