the ages of a sample of 25 salespersons are as follows: 21 24 24 26 28 28 30 30 31 32 34 34 35 36 37 38 40 41 43 45 45 45 47 53 56 manually draw a frequency histogram with six classes using range interval from 20 to 56. if there are one or more observations that fall on the boundary between classes, then count them as members of the left class. how many observations fall into the 5th class?

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

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
