On his first 5 tests, che averaged 92 points. on his next 3 tests hw scored 94, 85, and 85 points. what was his average for all 8 tests?

90.5

Step-by-step explanation:

To get the average, we must add all the values and divide the sum by the amount of them:

The answer will be 90.5, which is his average through all eight tests.

To do this in one step:

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

the answer is:

mean: 6

mad: 2.14
