One simple model for a person running the 100 mm dash is to assume the sprinter runs with constant acceleration until reaching top speed, then maintains that speed through the finish line.
If a sprinter reaches his top speed of 10.6 m/sm/s in 2.44 ss , what will be his total time?

Problem 3-3 (Part Level Submission)
A review of the ledger of Windsor, Inc. at December 31 produces the following data for the preparation of annual adjusting entries:
| 1. | Salaries and Wages Payable, $0. There are 9 salaried employees. 4 employees receive a salary of $1,230 each per week, and 5 employees earn $750 each per week. Employees do not work weekends. All employees worked two days after the last pay period and before December 31. | |
| 2. | Unearned Rent Revenue, $376,020. The company began subleasing condos in its new building on November 1. Each tenant has to make a $5,400 security deposit that is not refundable until occupancy is ended. At December 31, the company had the following rental contracts that were paid in full for the entire term of the lease: |
| Date | Term (in months) |
Monthly Rent | Number of Leases |
|||
| Nov. 1 | 6 | $3,910 | 6 | |||
| Dec. 1 | 6 | $10,370 | 3 |
| 3. | Prepaid Advertising, $14,820. This balance consists of payments on two advertising contracts. The contracts provide for monthly advertising in two trade magazines. The terms of the contracts are as follows: |
| Contract | Date | Amount | Number of magazines Issues |
|||
| A650 | May 1 | $6,780 | 12 | |||
| B974 | Oct. 1 | 8,040 | 24 |
| The first advertisement runs in the month in which the contract is signed. | ||
| 4. |
Notes Payable, $80,520. This balance consists of a one year, 9%,
note that is dated June 1. Windsor is preparing for a meeting with potential investors. What is the net effect of the adjusting entries on net income? |

a A box in a certain supply room contains seven 40-watt light bulbs, five 60-watt bulbs, and six 75-watt bulbs. Suppose that three bulbs are randomly selected. a. What is the probability that exactly two of the selected bulbs are rated 75-watt? b. What is the probability that all three of the selected bulbs have the same rating? c. What is the probability that one bulb of each type is selected? d. What is the probability that at least two of the selected bulbs are rated 75-watt?

using excel, draw npv profile and find "two" IRRs.
There should be two IRRs. If you get two IRRs, the NPV profile graph should look like a parabola curve.
I figured out the first IRR which is 19% (19.45...% to be exact) but I can't seem to get the second one.

Tony Smith is listed as the named insured on an auto policy with 25/50/15 limits. He is involved in a car accident where he runs a red light and hits another vehicle. The other driver, Sam, claims that he has neck and back injuries from this accident.
You have been assigned this claim. What steps would you take to investigate this claim? what steps would you take to determine coverage? Determine liability?

Which are paired designs and which are two independent random sample designs? For each #, it's one or the other...
#1 (a) Study of shopping at Wal-Mart. Study is on whether more go in non-grocery door than the grocery door? Study is done by counting the number of people entering each door from 7-9pm every Monday for 2 months.
(b) Study of shopping at Wal-Mart, but to collect data the number of people entering each door from 7-9pm on non-grocery and grocery at random and NOT collect both each time together. For example, do a non-grocery count this Monday from 7-9pm, then non-grocery again Tuesday from 7-9pm, and then grocery on Wednesday from 7-9pm, etc.
#2 (a) Study is on the effect of magnetic fields on healing times. To collect data you take 100 random individuals prick a single finger on each. Half of them you use magnetic field on and the others you don't. You record healing time.
(b) Study is on the effect of magnetic fields on healing times. On each of the 100 participants you prick one finger on each hand. Apply magnetic field to one finger and nothing to the other. You measure healing times for fingers.
#3 (a) Taste testing is done in which each participant tries coke and pepsi both and rates them both. (b) Taste testing is done in which each person just tastes one and rates it and some other random person tastes the other and rates it.
#4 (a) Study of whether more movies are rented at Redbox on Friday or Saturday nights. Record rental numbers every week for 6 months on each Friday and the Saturday right after it.
(b) Study of whether more movies are rented at Redbox on Friday or Saturday. To get the data you randomly pick 24 Friday’s and then randomly pick 24 Saturday’s and record rentals on each. Note, it is NOT necessary for them to one right after the other.
#5 (a) Randomly pick 50 items that have been produced and use method one on it, then randomly pick another 50 and use method two on it.
(b) Match two items up because they came off production line together. Apply method one to one of them and method two to the other.

Write a program that checks if all the input numbers cover 1 to 99. Each ticket for the Pick-10 lotto has 10 unique numbers ranging from 1 to 99. Suppose you buy a lot of tickets and like to have them cover all numbers from 1 to 99. Write a program that reads the ticket numbers from a file and checks whether all numbers are covered. Assume the last ending number in the file is 0. Suppose the file contains the numbers
