Monique deposited her money in the bank to collect interest. The first month, she had $275 in her account. After the sixth month, she had $303.62 in her account. Use sequence notation to represent the geometric function. an = 275 ⋅ (1.02)n−1 an = 275 ⋅ (0.10)n−1 an = 303.62 ⋅ (1.02)n−1 an = 303.62 ⋅ (1.10)n−1

The total weight w, in pounds, of a tractor-trailer capable of carrying 8 cars depends on the number of cars c on the trailer. This situation is represented by the function rule. Make a table using appropriate values of c, graph the function rule, and then state whether the graph is continuous or discrete with a reason for your choice

Max is stacking logs at his campground for firewood. After his first load of logs, he has 9 logs on the stack. After his seventh load of logs, he has 51 logs on the stack. Use sequence notation to represent the arithmetic function. A an = 51 + 6(n − 1) B an = 9 + 6(n − 1) C an = 51 + 7(n − 1) D an = 9 + 7(n− 1)

A large university is interested in learning about the average time it takes students to drive to campus. The university sampled 238 students and asked each to provide the amount of time they spent traveling to campus. This variable, travel time, was then used conduct a test of hypothesis. The goal was to determine if the average travel time of all the university's students differed from 20 minutes. Suppose the sample mean and sample standard deviation were calculated to be 23.2 and 20.26 minutes, respectively. Calculate the value of the test statistic to be used in the test.
