A large corporation has thousands of employees. The distribution of annual salaries for the employees is

skewed to the right, with a mean of $68,000 and a standard deviation of $18,000. Because business has

been good this year, the CEO of the company decides that every employee will receive a $5000 bonus. Let

X be the current annual salary of a randomly selected employee before the bonus and Y be the employee's

salary after the bonus. Describe the shape, center, and variability of the probability distribution of Y.

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497

answer:   (s+1)(s+4)

step-by-step explanation:

factor s2+5s+4

s2+5s+4

=(s+1)(s+4)
