On average, 15 minutes elapse between discoveries of fraudulent corporate tax returns in a certain IRS office. What is the probability that more than 30 minutes will elapse before the next fraudulent corporate tax return is discovered

The probability that more than 30 minutes will elapse before the next fraudulent corporate tax return is discovered=0.1353

Step-by-step explanation:

We are given that

We have to find the probability that more that 30 minutes  will elapse before the next fraudulent corporate tax return is discovered.

Using exponential distribution

The probability that more than 30 minutes will elapse before the next fraudulent corporate tax return is discovered

The probability that more than 30 minutes will elapse before the next fraudulent corporate tax return is discovered

Hence, the probability that more than 30 minutes will elapse before the next fraudulent corporate tax return is discovered=0.1353

Since it's a quadrilateral, the measures of the angles have to add up to 360. First, subtract 216 (108×2) from 360 to get 144. Now divide 144 by 4 since you have 4x's that must add to 144. When you do the math, you'll find x=36. So the answer is A.
