DeShawn is using this frequency table to make a relative frequency table. What percent should he write in the Relative Frequency column for 5 to 9 push-ups?

g = 33%

Step-by-step explanation:

To solve this;

The values in the ends of the rows are found by adding together the two previous cells.

Thus;

For the first row, we would add the value in cell AC to the value in AD to get the value in the corresponding column named "Total".  This means we add 20% +g to get 53%;

Thus;

20% + g = 53%

Subtract 20% from each side to give;

g = 53% - 20%

g = 33%

Step-by-step explanation:

49.92 miles/hour

Step-by-step explanation:

32 miles/hour = 32 * 5280 = 168960 ft/hour

For the collision to occur, both cars must arrive at the intersection at the same time.

The time it takes for the Mercedes to travel 400 feet at the rate of 168960 ft/hour is 400 / 168960 = 0.002367 hours

So the Ferrari should take the same time to travel 624 feet as well, its speed would be

624 / 0.002367 = 263577.6 ft/hour or 263577.6 / 5280 = 49.92 miles/hour
