To find:The valid conclusion based on given information.

Answer to Problem 22STP
The correct conclusion is H.
Explanation of Solution
Given information:
According to a survey 90 physical trainers :
15 went for a run at least 5 times per week.
5 also swim during the week.
At least 25% of all trainers run and swim every week.
Conclusions:
F The report is accurate because 15 out of 90 is 25%.
G The report is accurate because 5 out of 15 is 33%, which is at least 25%.
H The report is inaccurate because 5 out of 90 is only 5.6%.
I The report is inaccurate because no one know if swimming exercising.
Calculation:
Consider that out of 90 physical trainers, 15 run five times in a week.
Out of them 15 trainers, 5 run and swim as well as.
Percentage of those who swim and run as well as out of 90.
Therefore, the correct conclusion is H.

- 9:41 … 93 Applying an Exponential Function to Newton's Law of Cooling 60. Water in a water heater is originally Aa ← 122°F. The water heater is shut off and the water cools to the temperature of the surrounding air, which is 60°F. The water cools slowly because of the insulation inside the heater, and the value of k is measured as 0.00351. a. Write a function that models the temperature T (t) (in °F) of the water t hours after the water heater is shut off. b. What is the temperature of the water 12 hr after the heater is shut off? Round to the nearest degree. c. Dominic does not like to shower with water less than 115°F. If Dominic waits 24 hr. will the water still be warm enough for a shower?
