Pls help I will put brainliest

47 years old

Step-by-step explanation:

21, 23, 30, 32, 32, 25, 43, 44, 46, 48, 49, 49, 50, 52, 52, 53, 55

First eliminate the one on the very end of the left side

23, 30, 32, 32, 25, 43, 44, 46, 48, 49, 49, 50, 52, 52, 53, 55

Eliminate 55

23, 30, 32, 32, 25, 43, 44, 46, 48, 49, 49, 50, 52, 52, 53

Eliminate 23

30, 32, 32, 25, 43, 44, 46, 48, 49, 49, 50, 52, 52, 53

Keep going until you get two numbers left or one number...

In this case, we are left with two numbers: 46 and 48.

To find the median age, we must find the average of these two numbers.

The median age is 47 years old.

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.
