Given : The histogram shows information about the speed of cars as they pa ss a checkpoint.

The scale on the frequency density axis is missing.

The histogram shows information about 480 cars.

To Find :

a) How many cars does the first bar represent?​

Solution :

15 to  30  on x axis has    , 24 on y axis

(30 - 15) * 24  =  360

30 to  35  on x axis has    , 33 on y axis

(35 - 30) * 33 =  165

35 to  50  on x axis has    , 5 on y axis

(50 - 35) * 5=  75

360 + 165 + 75  = 600

600  = 480

1  = 480/600

360  =  360 x 480/600  = 288

first bar represent = 288 Cars
