Find the average height of the building shown in the table hint to find the average of the values and divide the number of value

In order to find the average, you need to sum all values and the result divided by the number of values.

For example, let's say that you have these values: 2, 3, 4, 5 ,5 ,6 ,7.

The first

The second step is divide this result by the number of values:  

Hence, the average for this example is 4.6.

step-by-step explanation:

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
