Jackie buys 3 hot dogs and 1 pretzel from a restaurant for $12.25. Sylvia buys 2 hot dogs and 4 pretzels from the same restaurant for $16.50.
Part A
Which system of equations can be used to determine the price of a hot dog, h, and a pretzel, p, at the restaurant?
ββββββ2h + 1p = 12.25
3h + 4p = 16.50
ββββββ 2 h + 1 p = 12.25 , , 3 h + 4 p = 16.50,
2h + 1p = 12.25
3h + 4p = 16.50
2 h + 1 p = 12.25, , 3 h + 4 p = 16.50,
2h + 4p = 12.25
3h + 1p = 16.50
2 h + 4 p = 12.25 , , 3 h + 1 p = 16.50,
3h + 1p = 12.25
2h + 4p = 16.50

Use a calculator to verify that Ο(x) = 62, Ο(x2) = 1034, Ο(y) = 644, Ο(y2) = 93,438, and Ο(x y) = 9,622. compute r. (enter a number. round your answer to three decimal places.) as x increases from 3 to 22 months, does the value of r imply that y should tend to increase or decrease? explain your answer. given our value of r, y should tend to increase as x increases. given our value of r, we can not draw any conclusions for the behavior of y as x increases. given our value of r, y should tend to remain constant as x increases. given our value of r, y should tend to decrease as x increases.

Arandom sample of 15 observations is used to estimate the population mean. the sample mean and the standard deviation are calculated as 172 and 63, respectively. assume that the population is normally distributed. a. with 99 confidence, what is the margin of error for the estimation of the population mean? b. construct the 99% confidence interval for the population mean. c. construct the 95% confidence interval for the population mean. d. construct the 83% confidence interval for the population mean. hint: you need to use excel function =t.inv.2t to find the value of t for the interval calculation.
