1) The domain for f(x) and g(x) is the set of all real numbers. Let f(x) = 2x-3 and g(x) = 3x+8. Find f(x) multiplied by g(x). 2) The domain for f(x) and g(x) is the set of all real numbers. Let f(x) = x^2+x-20 and g(x)=x+5. Find f(x)/g(x) <-- (this is a fraction.) 3) Evaluate the piecewise function at x=-3 and x-11. 4) Find the inverse of the function. F(x) = 3x+7.

Tompkins Associates reports that the mean clear height for a Class A warehouse in the United Statesis 22 feet. Suppose clear heights are normally distributed and that the standard deviation is 4 feet. A Class A warehouse in the United States is randomly selected.A) What is the probability that the clear height is greater than 18 feet? P(x>18) = 0.8413B) What is the probability that the clear height is less than 11 feet? P(x<11) = ???C) What is the probability that the clear height is between 23 and 31 feet? P(23<= x <= 31) = ???(Round the values of z to 2 decimal places. Round your answers to 4 decimal places.)

An appliance manufacturer stockpiles washers and dryers in a large warehouse for shipment to retail stores. Sometimes in handling them the appliances get damaged. Even though the damage may be minor, the company must sell those machines at drastically reduced prices. The company goal is to keep the proportion of damaged machines below 2% One day an inspector randomly checks 66 washers and finds that 6 of them have scratches or dents. Is this strong evidence that the warehouse is failing to meet the companygoal? Test an appropriate hypothesis and state your conclusion. Be sure the appropriate assumptions and conditions are satisfied before you proceed.1) What is the value of the test statistic? If applicable2) What is the P-value of the test statistic? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. If applicable3) What is your conclusion? Assume alpha = 0.05.- his is strong evidence that less than 2% get damaged- his is strong evidence that more than 2% get damaged-This is not strong evidence that more than 2% get damaged-The assumptions and conditions are not met, so the test cannot proceed.2 %
