Answer:
1 2/14 ; 1 1/7
Step-by-step explanation:
To solve, change the division sign to a multiplication sign and flip the second fraction.
(4/7)/(2/4) = (4/7)(4/2)
Multiply across
(4 * 4)/(7 * 2) = (16)/(14)
Simplify. Change to mixed fraction (& further simplify if needed).
16/14 = 1 2/14

Answer:
B. The original purchase total must be at most to $44 before the discounts are applied.
Step-by-step explanation:
Solve the inequality by adding $10, then dividing by 0.8.
0.8x -$10 ≤ $25.20
0.8x ≤ $35.20 . . . . . . . . add $10
x ≤ $35.20/0.8 . . . . . . . divide by 0.8
x ≤ $44 . . . . . . . . . the before-discount purchase must be at most $44
The first thing we must do for this case is to observe the highest relative frequency of the table in the total column.
For the white car we have:
Male = 0.11
Female = 0.20
Total = 0.31
The percentage is given by:
(0.31) * (100) = 31%
Answer:
The percentage that represents the car bought most often is:
31%
