Alex is driving down Park Avenue on her way to meet friends for dinner. She receives a text message, with a change in the evening’s plans from a sushi bar to a pizza place. Upset about the switch from sushi to pizza, Alex focuses on her phone, taking her hands off the wheel and her eyes off the road as she explores alternative restaurant menus in the group text. Alex’s car slams into Robert’s car in front of her, causing Robert’s car to veer off the road into the center median. Robert’s head hits the windshield and he sustains a concussion. Robert’s car hits a trash can. The force of the impact causes the trash can to shatter, sending the trash can fragments flying. Lily, window shopping a quarter of a mile away, is hit by the flying debris and falls, breaking her arm on the icy sidewalk. Robert sues Alex, and Lily also sues Alex. Judgment for whom in each case?

The community park has a small lake where visitors can rent paddle boats at $1 for 15 minutes, up to 2 hours. After 2 hours, the rate increases to $3 for 30 minutes.

Problem Write the piecewise function to model this situation and graph the function.

  1. What is the rental charge at 15 minutes? At 16 minutes? At 45 minutes?

2. If you had only $15, how long could you rent a boat?

3. How are the two lines in the graph the same, and how are they different?

4. How would the graph change if the rate change occurred at ? = 1 hour?

5. How would the graph change if the fee were $2 for 15 minutes?

6. What is the rental fee at 3 hours?

1. Jupiter recently introduced her cousin Letecia to one of her colleagues working for the Avocado Park Development Council, whose name is Scheherazade. Letecia has decided to ask Scheherazade out on a date and her goats have jumped in to help. They don’t really understand human romantic customs, but they reason that humans base most of their behavior on money, so they want to start by estimating how much Letecia should expect to spend on a date. They collect a random sample of 52 first dates from residents of Avocado Park and ask how much money the dater spent (they discarded responses of zero as unhelpful). The results of their survey can be found under the questions. Thanks
   1. Identify the population of interest.
   2. Identify the variable of interest. What type of variable is it?
   3. If the goats want to estimate HOW MUCH Letecia should be expected to spend on this date, what parameter should they try to estimate?
   4. If the goats wish to estimate the parameter you chose in part c using a confidence interval, what conditions would need to be met? What assumptions would be necessary?
   5. Estimate the parameter you chose in part c with a confidence level of 90%.
   6. If Letecia can only afford to spend $80 on this date, should she worry that she’ll come off as cheap? Justify your answer.

Date Expense: 43,96, 70, 92, 87, 92, 70, 89, 65, 67, 43, 61, 57, 61, 75, 46, 83, 27, 81, 22, 127, 94, 86, 69, 102, 96, 59, 98, 72, 115, 117, 67, 55, 73, 84, 64, 62, 45, 51, 84, 74, 60, 82, 69, 41, 81, 62, 83, 120, 72, 97, 66

Cedar Point amusement park management is preparing the park's annual promotional plan for the coming season. Several advertising alternatives exist: newspaper, television, radio, and displays at recreational shows. The information below shows the characteristics associated with each of the advertising alternatives, as well as the maximum number of placements available in each medium. Given an advertising budget of $125,000, how many placements should be made in each medium to maximize total audience exposure? Formulate this as a linear programming problem to be solved using QM.

You decide you want to build a skate park in your backyard, so you need to buy a lot of concrete. The good news is, you can get a discount when you buy in bulk. The price of concrete for different grades of concrete per cubic yard is as follows:

• when grade is either "low" or "cheap"
  • $100 (per cubic yard) for less than 200 cubic yards
  • $95 for between 200 and 400 (including 200 and 400) cubic yards
  • $90 for more than 400 cubic yards
• when grade is either "high" or "expensive"
  • $150 for less than 250 cubic yards
  • $135 for 250 or more cubic yards

Write a program that calculates the price of an order of concrete when given the grade and quantity.

Notes

• You can assume valid input.
• The grader is checking if your output ends with the integer dollar amount (no cents or punctuation).

Examples

What grade of concrete (low/cheap, high/expensive)?
low
How many cubic yards of concrete?
75
The cost is $7500

The answer to the example above is calculated from 75 * $100 (low grade, less than 200 cubic yards) = $7500

What grade of concrete (low/cheap, high/expensive)?

The cost is $7500

What grade of concrete (low/cheap, high/expensive)?
high
How many cubic yards of concrete?
75
The cost is $11250

What grade of concrete (low/cheap, high/expensive)?

6.   Jiffy Park Corp. has annual sales of $50,705,000, an average inventory level of $15,015,000, and average accounts receivable of $10,015,000. The firm's cost of goods sold is 85% of sales. The company makes all purchases on credit and has always paid on the 30th day. However, it now plans to take full advantage of trade credit and to pay its suppliers on the 40th day. The CFO also believes that sales can be maintained at the existing level but inventory can be lowered by $1,950,000 and accounts receivable by $1,950,000.

      a.   What is Jiffy Park’s cash conversion cycle (CCC) prior to the changes proposed?

      b.   What is Jiffy Park’s CCC after implementing the suggested changes?

      c.   What is the net change in Jiffy Park’s CCC given what you just calculated above?

theme park owner wants to know if the children’s rides are favoring 10 year old girls over 10 year old boys based on height. In other words, does one group taller than the other and thus can go on more rides?

Part a: The owner gathered height data on 10 year old girls and 10 year old boys, see data below. Determine at the 5% significance level if there is evidence that the two genders are not the same height and thus cannot all go on the same rides. Show your work and give your answer in complete sentences in context of the problem.

Part b: After doing some research, the owner found the following information about the expected height and standard deviation for 10 year olds. Does that change the result of part a? Show your work and give your answer in complete sentences in context of the problem.
