5)Two girls ?1 = 21.0 kg and ?2 = 29.0 kg are standing 1.00 m away from the center of a rotation platform (Figure (a)), and the platform rotates at angular speed of 3.00 rad/s. Then both girls begin to walk towards the edge of the platform. If the radius of the platform is 2.00 m, what is the final angular speed of the system, when the girls reach the platform’s edge (Figure (b))? Model the platform as a uniform disk of mass M =350 kg, and the girls as point masses. The moment of inertia of a disk of mass M and radius R is 2 2 1 I disk = MR .

The body temperatures in degrees Fahrenheit of a sample of adults in one small town are:

Assume body temperatures of adults are normally distributed. Based on this data, find the 95% confidence interval of the mean body temperature of adults in the town. Enter your answer as an open-interval (i.e., parentheses) accurate to 3 decimal places. Assume the data is from a normally distributed population.

5 In a certain northern Wisconsin town (cough...cough...Oliver), there are 100 families. 30 families have 1 child, 50 families have 2 children, and 20 families have 3 children. The children are then ranked according to age: the oldest has rank 1, second oldest rank 2, third oldest rank 3. Suppose you select a random child from the town. Find the probability mass function, expected value, and variance of the childs rank.

PART 1 For each of the following statements, indicate symbolically the information given in the statement or the question. If you are not given a numeric value, then end your equation with a “?” Example: Given that the registered voter is an independent(I), the probability the voter opposes(O) the proposition is 0.80. Answer: P(O│I) = 0.80 1. The probability that a driver will be exceeding the speed limit (E) is 0.15. 2. When a new machine is functioning properly (F), only 3% of items produced are defective (D). 3. What is the probability that a randomly selected driver on the freeway will exceed the speed limit (E) and be stopped by the highway patrol (S)? 4. If a driver is exceeding the speed limit on the freeway (E), the probability that the driver will be stopped by the highway patrol (S) is 0.01. 5. If a driver is not exceeding the speed limit on the freeway (EC), the probability that the driver will be stopped by the highway patrol(S) is 0.001. 6. What is the probability that a driver on the freeway was neither stopped by the highway patrol (S) nor was exceeding the speed limit (E)? 7. What is the probability that a driver on the freeway who has been stopped by the highway patrol (S) was exceeding the speed limit (E)? 8. Past experience indicates that for 75% of successful bids (S) the agency requested additional information (I). 9. If a student goes to school full time (F), the probability that school quality is the first reason for choosing a school (Q) is 0.473. 10. What is the probability that a randomly chosen student goes to school full time (F) or has school quality as the first reason for choosing a school (Q)? 11. The Dallas IRS auditing staff believes that the probability of finding a fraudulent return (F) given that the return contains deductions for contributions exceeding the IRS standard (E) is 0.20.  

11. Suppose a school principal is trying to increase academic outcomes by providing snacks to students. She is allocating her money between two snack inputs: bananas and yogurt. She has a budget of $400. A carton of bananas costs $40, and a bundle of yogurts costs $50.

a) Draw the principal’s budget constraint, putting bananas on the x-axis and yogurts on the y-axis. Write down the equation for the budget constraint.

b) Suppose productive efficiency occurs at the point where she consumes 5 cartons of bananas and 4 bundles of yogurts. Label this point “PE” and draw the corresponding isoquant line at the point of efficient allocation.

c) Suppose the school district implements an input policy that specifies schools must spend their budget on providing at least 4 cartons of bananas to students. How will this change the way the principal allocates between bananas and yogurt? Explain.

d) Suppose that instead of an input policy, the school district implements a total resource policy and give the school a budget of $500 instead of $400. How does this change the amount of bananas purchased at the point of productive efficiency? How does this change the number of yogurts purchased? What is the slope of the isoquant at the new point of productive efficiency?

You found an exciting summer job for five weeks.

Suppose that the total tax you pay on your summer job income is 14%.

After paying the taxes, you spend:

• You spend 10% of your net income to buy new clothes and other accessories for the next school year
• You 1% to buy school supplies
• AFTER buying clothes and school supplies, you save 25% of the remaining money
• For each dollar you save, your parents add $0.50 additional savings

Write a program that prompts the user to enter the pay rate for an hour and
the number of hours you worked each week.

For example, if you earned $10.00/hour and worked 10 hours per week....
the program should output the following:

|----------|--------------------------------------------------|
| $ 10.00 | Hourly Rate |
| 50.00 | Total Hours Worked |
|----------|--------------------------------------------------|
| $ 500.00 | Total Income before tax |
| $ 430.00 | Net Income |
| $ 43.00 | Money spent on clothes and other accessories |
| $ 4.30 | Money spent on school supplies |
| $ 95.67 | Money spent on savings |
| $ 47.84 | Money spent by parents on additional savings |
|----------|--------------------------------------------------|
