Mathematics
2 answers:
Mkey [24]3 years ago

Answer:

12

Step-by-step explanation:

The mean is the average of a set of data. To find the mean you would add all of the values and then divide by the amount of values you have.

The values on the chart are: 12,13,14,9

There are 4 bars on the chart, and 4 values.

12+13+14+9 = 48

then you'd divide: 48/4

12 is your mean.

Add all then divide by 4
12 + 13 + 14 + 9 = 42
So 42/4 = 10.5

A. 34.4 B. 40 C. 43.2 D. 45
horsena [70]
Answer: 40

-----------------------------------------------------------------------------

Notice how WI = 12 is one-third of IL = 36
So AM is going to be one-third of ML = 30 making AM = 10
AL = AM+ML = 10+30 = 40
AL = 40

Or a more formal way to do it is to use ratios
AL/ML = WL/IL
AL/ML = (WI+IL)/IL
AL/30 = (12+36)/36
AL/30 = 48/36
36*AL = 30*48
36*AL = 1440
AL = 1440/36
AL = 40
Either way we get the same answer
