The histogram shows the ages of all the workers in a London office. Given that 24 people are in the 40 - 55 age range, work out the total number of people in the office

40 people

Step-by-step explanation:

First thing, you have to find the area below the 40 - 55 line in the histogram. The area can be find using the area of a rectangle: side × side

Doing this you'll find an area of 60.

After that, find the total area of the histogram in the same way: separate it in rectangles and use the formula for the area of a rectangle, and after you'll find a total area of 100

Now you have to do a rule of three:

We know from the question statement that the amount of people with 40 - 55 years old is 25, and that area correspond to 60, so:

60 24

100 x

60•x = 24•100

60x = 2400

x = 2400/60

x = 40

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.
