The Celluloid Cinema sold 150 tickets to a movie. Some of these were child tickets and the rest were adult tickets. A child ticket cost $7.75 and an adult ticket cost $10.25. If the cinema sold $1470 worth of tickets, which system of equations could be used to determine how many adult tickets, a, and how many child tickets, c, were sold? A)a+c=150a+c=150
10.25a+7.75c=147010.25a+7.75c=1470< br />
B)a+c=150a+c=150
7.75a+10.25c=14707.75a+10.25c=1470< br />
C)a+c=1470a+c=1470
10.25a+7.75c=15010.25a+7.75c=150

D)a+c=1470a+c=1470
7.75a+10.25c=1507.75a+10.25c=150

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
