What type of function best models the relationship between the descending airplane’s altitude and time? Decreasing exponential Decreasing linear Increasing exponential Increasing linear 3 / 22 The data in the table above were produced by a sleep researcher studying the number of dreams people recall when asked to record their dreams for one week. GroupX consisted of 100 people who observed early bedtimes, and GroupY consisted of 100 people who observed later bed times. If a person is chosen at random from those who recalled at least 1 dream, what is the probability that the person belonged to GroupY ? 68 / 100 79 / 100 79 / 164 164 / 200 4 / 22 On Saturday afternoon, Armand sent m text messages each hour for 5 hours, and Tyrone sent text messages each hour for 4 hours. Which of the following represents the total number of messages sent by Armand and Tyrone on Saturday afternoon? 9mp 20mp 5m + 4p 4m + 5p 5 / 22 The complete graph of the function f is shown in the xy-plane below.

Which statement is the best interpretation of 2 in this context? f(x) = 4x + 2 The tree will be measured each year for 2 years. The tree is estimated to grow to a maximum height of 2 feet. The estimated height of the tree increased by 2 feet each year. The estimated height of the tree was 2 feet when it was first measured. 9 / 22 Suppose x(a3am+5) = a2m+8. Express x in terms of a and m. x = am x = am+2 x = ma x = ma+1 10 / 22 The function f is defined by f(x) = 8x. For what value of x does f(x) = 16? 2 4 6 8 11 / 22 The function f is defined by f(x) = x2 + x + 100. What is the value of f(5)? 130 120 140 110 12 / 22 Each side of equilateral triangle S is multiplied by a scale factor of k to create equilateral triangle T. The length of each side of triangle T is greater than the length of each side of triangle S.

The outlier measurement of 24 inches is an error. Of the mean, median, and range of the values listed, which will change the most if the 24-inch measurement is removed from the data? Mean Median Range They will all change by the same amount. 16 / 22 For what value of n is |n−1| + 1 is equal to 0 ? 0 1 2 There is no such value of n. 17 / 22 If 16 + 4x is 10 more than 14, what is the value of 8x ? 2 6 16 80 18 / 22 The function f(w) = 4w2 gives the area of a rectangle, in square feet(ft2), if its width is w ft and its length is 4 times its width. What is the best interpretation of f(10) = 400? If the width of the rectangle is 10 ft, then the area of the rectangle is 400ft2. If the width of the rectangle is 10 ft, then the length of the rectangle is 400ft. If the width of the rectangle is 400 ft, then the length of the rectangle is 10ft. If the width of the rectangle is 400 ft, then the area of the rectangle is 10ft2. f(10) = 4(10)2 = 400 ft2 19 / 22 The graph below displays the total cost C, in dollars, of renting a boat for h hours.
