A salon owner estimates the number of clients she is expecting during the festive season to be 20% during Monday to Wednesday, 20% on Thursday and 60% over the weekend. She therefore hires additional staff to assist during the weekend to meet the client demand. She however only observes 30% during Monday to Wednesday, 20% on Thursday and 50% over the weekend in the first week of December. The salon owner is uncertain whether she should reduce the planned staff for the December festive period due the observed trend or not. She conducts a statistical test at α = 0.05 to determine if the observed trend fits the expected trend. Which of the following statements is true? A. The conclusion of the test is that she should not keep the additional staff for the weekend. B. The df for this test is 3. C. The p-value is greater than α. D. The null hypothesis is that the observed trend is different to the expected trend. E. The test statistic is χ2 = 5.33.
You currently earn $1300 per month, but you are expecting your earnings to rise 20% per year. In five years, what should you expect to be earning? A) In five years, you should expect to be earning exactly $1300 per month because the 20% increase in earnings does play any effect. B) In five years, you should expect to be earning somewhat more than $1300 per month because the 20% increase in earnings is very small. C) In five years, you should expect to be earning somewhat more than $1560 per month because your earnings rise 20% per year, which are added to the earnings of the previous month. D) In five years, you should expect to be earning exactly $1560 per month because your earnings rise 20% per year, or $260 dollars per year. E)In five years, you should expect to be earning somewhat less than $1560 per month because your earnings rise 20% per year, which are subtracted from the earnings of the previous year. F)In five years, you should…
1.) With summer winding down, Mr. and Mrs. Mallery decided to take their family to the beach one last time. They loaded their kids, Olivia and Liam, into the car and headed off early in the morning. At 7:05 Olivia asked, "Are we there yet?" "We're one-third of the way there," replied Mr. Mallery. %3D At 7:25 Liam asked, "Are we there yet?" "We're 75% of the way there," said Mrs. Mallery. "Now, can you two figure out what time we %3D should get to the beach?" Assuming the Mallerys maintain a constant speed during their trip, at what time they will arrive at the beach?
A certain city's power company charges their residents for electricity usage on a daily basis. There is a basic charge of 11.57 cents. For each day the first 10 kWh cost 4.81 cents per kWh and any additional kWhs are 9.69 per kWh. (A kWh, or kilowatt-hour, is a unit of energy.) (a) Complete the following table using the information provided above. kWhkWh 0 5 10 15 20 cost (dollars)cost (dollars) kWhkWh 25 30 35 40 cost (dollars)cost (dollars) (b) We can define a piecewise function f(x)f(x) where xx is the kWh used in a day and f(x)f(x) is the cost, in dollars. This function would have the form f(x)={g(x)h(x)ififx∈Ax∈Bf(x)={g(x)ifx∈Ah(x)ifx∈B What functions g(x)g(x) and h(x)h(x) make up the piecewise function f(x)f(x)? g(x)=g(x)= for A = h(x)=h(x)= for B = Hint: A and B are intervals. If an interval uses ±∞±∞ write inf or -inf . (c) Using the above function, what is the cost of 26 kWh? dollars. (d) For 3 dollars, what is the maximum kWh usage for one…

A surfboard manufacturer lost $500,000 last year during a recession. Total revenue was $5,000,000 and total variable costs were 40% of sales. The production facility ran at 50% capacity. The production manager wants to know the following: a. What is the percent capacity required to break even? b. When the economy recovers this year, if the plant runs at 100% capacity what net income could the company realize? c. There is a possibility that sales could be so strong this year that the plant may be required to run at 120% capacity by offering a lot of overtime to its production workers. This would result in total variable costs rising by 35%. On a strictly financial basis, should the production manager plan to exceed capacity or should he advise top management to freeze production at 100% capacity? Justify your answer. Answer Solution- 9a. 58.3% 9b. $2,500,000 9c. $3,100,000
Two students in a microeconomics class traveled to a football game just before the midterm and drank too much to be able to study. So they telephoned their professor and lied to him, saying that a flat tire had delayed them. "No problem," said the professor. "Take the test tomorrow." When they arrived, the professor put each student in a separate room for taking the test. The first question, worth 5 points, was easy. The second question was worth 95 points: "Which tire?" Calculate, for each student, the expected test score.
