Find the mean (average) for the data set: 8, 12, 13, 7, 12 and 20.

12

Step-by-step explanation:

The mean or average is simply all the numbers added up and then divided by the number of numbers put in. In this case:

8+12+13+7+12+20=72

There are 6 numbers put into the equation s you divide your answer by 6

72/6 = 12

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!

answer: no

step-by-step explanation: because the big angle will spread away the 2 side that it is on and make the opposite side even longer.
