Harry had $32. He spent all the money on buying 3 notebooks for $x each and 4 packs of index cards for $y each. If Harry had bought 5 notebooks and 5 packs of index cards, he would have run short of $18. A student concluded that the price of each notebook is $5 and the price of each pack of index cards is $1. Which statement best justifies whether the student's conclusion is correct or incorrect?a. The student's conclusion is incorrect because the solution to the system of equations 3x + 4y = 32 and 5x + 5y = 50 is (8, 2).b. The student's conclusion is incorrect because the solution to the system of equations 3x + 4y = 32 and 5x + 5y = 18 is (8, 2).c. The student's conclusion is correct because the solution to the system of equations 3x + 4y = 32 and 5x + 5y = 18 is (5, 1).d. The student's conclusion is correct because the solution to the system of equations 3x − 4y = 32 and 5x − 5y = 50 is (5, 1).

A soft drink company has recently received customer complaints about its one-liter-sized soft drink products. Customers have been claiming that the one-liter-sized products contain less than one liter of soft drink. The company has decided to investigate the problem. According to the company records, when there is no malfunctioning in the beverage dispensing unit, the bottles contain 1.01 liters of beverage on average, with a standard deviation of .13 liters. A sample of 70 bottles has been taken to be measured from the beverage dispensing lot. The mean amount of beverage in these 70 bottles was 0.993 liters. Find the probability of observing a sample mean of 0.993 liters or less in a sample of 70 bottles, if the beverage dispensing unit functions properly. Carry your intermediate computations to at least four decimal places. Round your answer to at least three decimal places.

The shift supervisor of a pizza parlor claimed that the population mean total time to deliver a pizza is exactly 45 minutes. Paige, the owner, would like to find evidence that the population mean total time to deliver a pizza is less than 45 minutes so she records the total delivery time of 71 randomly selected deliveries and she finds that the sample mean is 44.06 minutes with a sample standard deviation of 3.46 minutes. The test statistic t for a hypothesis test of H0:μ=45 versus Ha:μ<45 is t≈−2.29. If 0.01a. Reject he null hypothesis that the true population mean total time to deliver a pizza is equal to 45 minutes. b. Fail to reject the null hypothesis that the true population mean total time to deliver a pizza is equal to 45 minutes. c. There s not enough evidence at the r = 0.05 level of significance to suggest that the true population mean total time to deliver a pizza is not equal to 45 minutes. d. There is enough evidence at the a 005 level of significance to support the claim that the true population total time to deliver a pizza is less than 45 minutes

Determine whether the following probability experiment represents a binomial experiment and explain the reason for your answer.An investor randomly purchases 17 stocks listed on a stock exchange. Historically, the probability that a stock listed on this exchange will increase in value over the course of a year is 47%.The number of stocks that increase in value is recorded.Does the probability experiment represent a biniomialexperiment?A. No, because there are more than two mutually exclusive outcomes for each trial.B. No, because the trials of the experiment are not independent.C. Yes, because the experiment satisfies all the criteria for a binomial experiment.D. No, because the probability of success differs from trial to trial.

In Lesson 1.4, you learned about a water footprint. Part of a person's water footprint is the water used for cleaning. In this question, you will calculate the cost of water for laundry and bathing. You will use the City of New York 2011 rate of $7.64/100 cubic feet of water. Calculate the cost of each of the following based on this rate. Use the conversion factor of 7.48 gallons per cubic foot. a. A standard washing machine uses approximately 50 gallons of water per load4 . A household washes one load of laundry per week for 52 weeks. Find the total cost per year. 2655. # b. According to one study, the average American shower lasts for 8.2 minutes and uses 17.2 gallons. A person showers once a day for a year (365 days). Find the total cost per year. $ 6412.9 * /yr
