7/28 in reduced fraction
Bess [88]
7/28
(Now we divide both sides by 7 since they can easily be divided by 7)
7÷7=1
28÷7=4

Since we can't divide 1/4 anymore, 7/28 as a simplified fraction is 1/4.

The box plots show the average speeds, in miles per hour, for the race cars in two different races.
Murljashka [212]

Answer:

The correct option is;

The median speed in race A is about 153 miles per hour and the median speed in race B is about 145 miles per hour.

Step-by-step explanation:

Here we have the  box plot which shows the following 5 values

Race A

Maximum = 170 miles per hour

Minimum = 120 miles per hour

1st quartile  ≈ 142 miles per hour

Median or 2nd quartile ≈ 153 miles per hour

3rd quartile = 165 miles per hour

Race B

Maximum = 165 miles per hour

Minimum = 125 miles per hour

1st quartile  ≈ 139 miles per hour

Median or 2nd quartile = 145 miles per hour

3rd quartile = 150 miles per hour

Therefore, the correct option is as follows;

The median speed in race A is about 153 miles per hour and the median speed in race B is about 145 miles per hour.
