The probability that Evelyn is on time for a given class is 40 percent. If there are 45 classes during the semester, what is the best estimate of the number of times out of 45 that Evelyn is on time to class? Round your answer to the nearest integer.

18

Step-by-step explanation:

40/100 x 45 = 2/5 x 45 = 18

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

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20
