Answer:

x=6

y=9

z=10

Step-by-step explanation: The long 20 on the left has 4, 6 and _10_ to make 20. The blank which is 10 is the same length as z. The proportion of 10/15 translates throughout the whole shape. That means it is 6/9 and 4/6.

The simplified proportion is 2/3 by the way.

Answer:

$5.5$

Step-by-step explanation:

Mean:

The mean of a data set is commonly known as the average. You find the mean by taking the sum of all the data values and dividing that sum by the total number of data values. The formula for the mean of a population is

$\mu = \frac{{\sum}x}{N}$

The formula for the mean of a sample is

$\bar{x} = \frac{{\sum}x}{n}$

Both of these formulas use the same mathematical process: find the sum of the data values and divide by the total. For the data values entered above, the solution is:

$\frac{55}{10} = 5.5$
