Answer:
The value of y is 89.55 at x=15 and 60.69 at x=9.
Step-by-step explanation:
The equation of best fit line is
where, y is scores of two students after x working hours.
We need to find the score after 15 and 9 hours.
Substitute x=15 in the given equation.
Substitute x=9 in the given equation.
Therefore, the value of y is 89.55 at x=15 and 60.69 at x=9.

Answer:
The expected value for the insurance company is $200
Step-by-step explanation:
In order to calculate the expected value for the insurance company we would have to make the following calculation:
expected value for the insurance company=expected value live+expected value die
expected value live=Net gain*probability of living
expected value live=$300*0.999=$299.70
expected value die=Net gain*probability of die
expected value die=(-$100,000 + $300)*0.001
expected value die=$-99.70
Therefore, expected value for the insurance company=$299.70-$99.70
expected value for the insurance company=$200
The expected value for the insurance company is $200
