If an integer from 3 through 14 is chosen at random, what is the

probability that the number chosen is NOT prime?

Step-by-step explanation:

Given

There are integer between 3 and 14 available to be chosen (total 12 integers)

Prime integers among them

3,5,7,11,13 i.e. total of 5 prime integers

So the probability that the number chosen is not Prime

a

b

d

step-by-step explanation:

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
