A certain college graduate borrows $8,937 to buy a car. The lender charges interest at an annual rate of 16% . Assuming that interest is compounded continuously and that the borrower makes payments continuously at a constant annual rate, determine the payment rate that is required to pay off the loan in 6 years. Also determine how much interest is paid during the 6 -year period. When calculating the interest use the non-rounded value of the payment rate, then round all answers to two decimal places.

Payment rate = $_____ per year

Interest paid = $ ______ per year

Consider a 5x5 chessboard. Prove that no matter how the 25 cells are colored in red and blue (each cell is either red or blue), there exist 4 cells of the same color whose centers determine a rectangle with sides parallel to the sides of the board. Is the statement true for a 4x4 chessboard? What about 4x6 chessboard?

6. Let V be the vector space above. Consider the maps T : V → V And S : V → V

4. Consider bit strings with length l and weight k (so strings of l 0’s and 1’s, including k 1’s). We know how to count the number of these for a fixed l and k. Now, we will count the number of strings for which the sum of the length and the weight is fixed. For example, let’s count all the bit strings for which l + k = 11.

(a) Find examples of these strings of different lengths. What is the longest string possible? What is the shortest?

(b) How many strings are there of each of these lengths. Use this to count the total number of strings (with sum 11).

(c) The other approach: Let n = l + p vary. How many strings have sum n = 1? How many have sum n = 2? And so on. Find and explain a recurrence relation for the sequence (an) which gives the number of strings with sum n.

(d) Describe what you have found above in terms of Pascal’s Triangle. What patter have you discovered?

I'd really appreciate the help on solving this problem as there were no similar example problems in the book to even help me start this problem. Thank you!

Also some background information on this problem to hopefully help someone at least start answering this problem. For this problem we previously went over sequences such as recursive and closed. Also if they were arithmetic or geometric. The last chapter did cover binomial coefficients if that has some prevalence here.

A researcher believes that female stray cats are more cautious when approaching people than male cats. He knows that the stray cat population is 50% male and 50% female. In order to test this, visits 15 different areas where stray cats live and records the gender of the first cat to approach him. He finds that 12 of the 15 cats that approach him are male. Using a sign test:

D) What is the critical value? (In number of female cats)

1. Explain how loss to follow-up could bias findings in a cohort study of physical activity in college and subsequent diagnosis of diabetes.
2. Explain how recall bias could affect a case-control study of type 2 diabetes diagnosed in adults age 45 to 64 years and physical activity during young adulthood (while age 18 to 24 years)
3. Explain how selection bias could affect a case-control study of type 2 diabetes diagnosed in adults age 45 to 64 years and physical activity during young adulthood. Assume cases are identified as adult diabetic patients attending a diabetes management seminar at a local hospital and controls are selected from non-diabetic patients admitted to the hospital during the week the seminar was offered. Further assume that cases and controls are matched on age and sex.
