5.The average time required to complete an accounting test has been determined to be 55 minutes.Assuming that times required to take tests are exponentially distributed, how many students from aclass of 30 should be able to complete the test in between 45 and 60 minutes? Draw the graph forthis information.

Here we have to use the exponential distribution formula,Given that,the rate parameter , as the…

In October 2005, a company employs 11000 people and its total monthly wage bill is 11 million dollars. What is the average monthly wage of the company's employees? Average monthly wage : ___dollars. The company is growing at a rate of 10 employees per month. The total monthly wage bill is increasing at a rate of 260 thousand dollars per month. At what rate is the average monthly wage changing at this time? Give your answer correct to the nearest cent per month. Rate of change: ___ dollars per month. You should be careful over the units in this question. Hint: write the total monthly wage bill as the function f (t) and the number of employees as the function g (t). What is the average monthly wage in terms of the functions f and g?
A graphing calculator is recommended.A dealer predicts that new cars will sell at the rate of 5xe−0.2x sales per week in week x. Find the total sales in the first half year (week 0 to week 26). (Round your answer to the nearest whole number.)
2. You bought a new computer for $2,500. Four years later, your computer is valued at $1,250. a. Assume that the cost function will be linear and write a linear function to describe the cost of the computer ?t years after you bought it. b. Assume that the cost function will be exponential (think of exponential decay) and write an exponential function to describe the cost of the computer ?t years after you bought it. c. For each function you just wrote, find the rate at which the cost is depreciating 3 years after you bought it. d. Which function do you think would be more accurate? Write a complete sentence or two describing why you think so.
A graphing calculator is recommended. Straight-line depreciation is a method for estimating the value of an asset (such as a piece of machinery) as it loses value ("depreciates") through use. Given the original price of an asset, its useful lifetime, and its scrap value (its value at the end of its useful lifetime), the value of the asset after t years is given by the formula for 0 ≤ t ≤ (Useful lifetime). (a) A farmer buys a harvester for $40,000 and estimates its useful life to be 20 years, after which its scrap value will be $4000. Use the formula above to find a formula for the value V of the harvester after t years, for 0 ≤ t ≤ 20. (Do not use commas in your answer.) V = Value = Price - (b) Use your formula to find the value of the harvester after 5 years. V(5) = No Solution (c) Graph the function found in part (a) on a graphing calculator on the window [0, 20] by [0, 40,000]. (Hint: Use x instead of t.)

Section 2.2 (81) In the early stages of the deadly SARS (severe acute respiratory syndrome) epidemic in 2003, the number of cases was increasing by about 18% each day. On March 17, 2003 (the first day for which statistics were reported by the World Health Organization), there were 167 cases. Find an exponential model that predicts the number of cases "t" days after March 17, 2003, and use it to estimate the number of cases on March 31, 2003. (The actual reported number of cases was .)
