A manager asked her employees how many times they had given blood in the last year. The results of the survey are given below. The random variable x represents the number of times a person gave blood and P(x) represents the probability of selecting an employee who had given blood that percent of the time. What is the mean number of times a person gave blood based on this survey

Complete Question

The probability distribution table is given below:

1.61

Step-by-step explanation:

The probability distribution table is given below:

We want to determine the mean number of times a person gave blood.

Expected Value,

The mean number of times a person gave blood based on this survey is 1.61.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
