(Data Processing) a. Create a text file containing the following data (without theheadings): b. Write a C++ program that reads the data file created in Exercise 7a and computes and displays a payroll schedule. The output should list the Social Security number, name, and gross pay for each person, calculating gross pay as Hourly Rate $\times$ Hours Worked.

Name	Social Security Number	Hourly Rate	Hours Worked
B Caldwell	555-88-2222	7.32	37
D Memcheck	555-77-4444	8.32	40
R Potter	555-77-6666	6.54	40
W Rosen	555-99-8888	9.80	35

In preparing the direct materials budget for Quan Company, management concludes that required purchases are 64,000 units. If 52,000 direct materials units are required in production and there are 9,000 units of beginning direct materials, what is the desired units of ending direct materials?

Using the methods of this section: (a) Find the first few terms of the Maclaurin series for each of the following functions. (b) Find the general term and write the series in summation form. (c) Check your results in (a) by computer. (d) Use a computer to plot the function and several approximating partial sums of the series. $\ln \sqrt{\frac{1+x}{1-x}}=\int_{0}^{x} \frac{d t}{1-t^{2}}$

The letters R, C and A can be combined in several different ways. a) Write the letters in as many different orders as possible. If a computer writes these three letters at random, calculate the probability that: b) the letters will be written in alphabetical order, c) the letter $R$ is written before both the letters A and C, d) the letter C is written after the letter A, e) the computer will spell the word CART if the letter T is added.

Bits & Bytes, Inc., started the month with an inventory of computer hardware and software valued at $68,395.65. During the month, Bits & Bytes bought 16 scanners at a cost of$47.84 each, 24 CD burners at a cost of $37.75 each, and 48 software programs at a cost of$14.95 each. Bits & Bytes': ending inventory of computer hardware and software was valued at $52,936.89. What was the cost of the goods sold?

What materials are filtered from the blood in the kidney? What materials remain in the blood?

On March 28, 2008, Toyota Motor Credit Corporation (TMCC), a subsidiary of Toyota Motor, offered some securities for sale to the public. Under the terms of the contract, TMCC promised to repay the owner of one of these securities $100,000 on March 28, 2038, but investors would receive nothing until then. Investors paid TMCC$24,099 for each of these securities; so they gave up $24,099 on March 28, 2008, for the promise of a$100,000 payment 30 years later.

Suppose that when TMCC offered the security for $24,099, the U.S. Treasury had offered an essentially identical security. Do you think it would have had a higher or lower price? Why?

Identify the control document for materials flow when a materials requisition slip is not used.

The amount of time, in hours, that a computer functions before breaking down is a continuous random variable with probability density function given by

$$f(x)=\left\{\begin{array}{ll}{\lambda e^{-x / 100}} & {x \geq 0} \\ {0} & {x<0}\end{array}\right.$$

What is the probability that a computer will function between 50 and 150 hours before breaking down? What is the probability that it will function less than 100 hours?

Using the methods of this section: (a) Find the first few terms of the Maclaurin series for each of the following functions. (b) Find the general term and write the series in summation form. (c) Check your results in (a) by computer. (d) Use a computer to plot the function and several approximating partial sums of the series. $\ln (x+\sqrt{1+x^{2}})=\int_{0}^{x} \frac{d t}{\sqrt{1+t^{2}}}$

Lenny Fiorita, an unmarried employee, works 48 hours in the week ended January 12. His pay rate is $14 per hour, and his wages have deductions for FICA Social Security, FICA Medicare, and federal income taxes. He claims two withholding allowances.

Compute his regular pay, overtime pay (Lenny earns$21 per hour for each hour over 40 per week), and gross pay. Then compute his FICA tax deduction (6.2% for the Social Security portion and 1.45% for the Medicare portion), income tax deduction, total deductions, and net pay. Round tax amounts to the nearest cent.

One personal computer has a printer that can print a page in 30 seconds. A second computer has a printer that can print a page in 20 seconds.

a How long will it take to print a 500-page document if both printers work together?

b If the first printer starts on page 1, on what page should the second printer start in order for them to finish at approximately the same time?

Write a computer program to plot the graph of a geometric sequence on the computer's screen. The computer should let you input the first term and the common ratio. Then it should calculate and plot successive terms. You will have to read your computer's instruction manual to find out how to make it do graphics. The resulting program should produce a graph similar to that below for $t_1=9$ and $r=-0.95$.

Identify the type of sampling (random, systematic, convenience, stratified, cluster) used when a sample of the 637,133 stockholders is obtained as described. Then determine whether the sampling scheme is likely to result in a sample that is representative of the population of all 637,133 stockholders.

d. A computer file of all IBM stockholders is compiled so that they are all numbered consecutively, then random numbers generated by the computer are used to select the sample of stockholders.
