The original equation: 8(5.95)+8(4)+8(3.60)+8(2.25)= $126.4
To answer the question you should add all of the numbers within the parenthesis together: 5.95+4+3.60+2.25= $15.8
Then multiply that answer times the total number of people: 8(15.8)= $126.4
The lower quartile is 60. Quartiles are the numbers in the middle of the median and lowest/highest number.
Answer:
the answer is 6 u welcome
The angle in the dilated figure is the same as the original angle in each case, a fact that should be confirmed by the way the answer choices are shown.
∠A = ∠A'
... 4x -4 = 51 -x
... 5x = 55
... x = 11
∠A = 4·11 -4 = 40 . . . . . . doesn't match any offered choice
___
∠B = ∠B'
... 6x -1 = 4x +21
... 2x = 22
... x = 11
... ∠B = 6·11 -1
... ∠B = ∠B' = 65 . . . . . matches selection D)
_____
∠C = ∠C'
... 8x -13 = 6x +9
... 2x = 22
... x = 11
... ∠C = 6·11 +9 = 75
... ∠C = ∠C' = 75 . . . . . matches selection D)
