The weights (in pounds) of six dogs are listed below.

17 56 85 38 138 98

the measure of center is found to be 72 lb. which measure of center is used?

The measure of center is the average or mean.

Step-by-step explanation:

The weights (in pounds) of six dogs are listed below.  

17 56 85 38 138 98

Arranging in ascending order, we get

17  38 56 85 98 138

The measure of center is found to be 72 lb.

This is the average or mean. We can check this as:

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

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
