A total of 1,650 tickets were recently sold Friday night's football game. Each adult ticket cost $3.50, and each student ticket cost $2.00. The total revenue for ticket
sales was $4,650. Which system of equations below could be used to determine a,
the number of adult tickets sold, and s, the number of student tickets sold.
F 3.50a + 2.00s = 4,650
a + s = 1, 650
G 350a + 200s = 4,650
a + s = 1,650
H 3.50a + 2.00s = 1,650
a + s = 4,650
J 350a + 200s = 1,650
a + s = 4,650

Anull hypothesis states that the difference between 8 hours of sleep and 3 hours of sleep has no effect on the number of pictures a student will remember during a picture memory interface test (pmit). examining the mit database, an extremely small t-value of 0.1611 is found. this t-value is much smaller than the smallest t-value on the chart for p-value reference. from this information we can: select one: a. accept the null hypothesis because the p-value obtained shows that the difference between the two groups being tested is not statistically significant b. accept the null hypothesis because the p-value obtained was statistically significant c. reject the null hypothesis because of the p-value obtained d. reject the null hypothesis because the data obtained is statistically significant
