Question 1(multiple choice worth 1 points) (02.01) solve for x: the quantity of x plus 16 all over 3 = 3x x = −7 x = −13 x = 8 x = 2 question 2(multiple choice worth 1 points) (02.01) solve for x: 3(x + 1) = −2(x − 1) − 4. 1 −1 −5 −25 question 3(multiple choice worth 1 points) (02.01) solve for x: 5x + 2 = 4x − 9. 7 −7 11 −11 question 4(multiple choice worth 1 points) (02.01) the rectangle below has a total perimeter of 125 cm: picture of a rectangle with a width of 5 write an equation and solve it to find the length of the longer side of the rectangle. 2x + 10 = 125; x = 57.5 cm x + 5 = 125; x = 120 cm 5x = 125; x = 25 cm 25x = 125; x = 5 cm question 5 (fill-in-the-blank worth 2 points) (02.01) solve for x: 3 over 4 x + 5 over 8 = 4x x = write your answer as a fraction in simplest form. use the "/" symbol for the fraction bar. answer for blank 1: 10/9 question 6(multiple choice worth 1 points) (02.01) a social networking site recorded that 80% of the people who became members of the site one month were between 30 and 40 years old. the equation below represents this information, where x represents the total number of people who became members of the site that month: x = 0.8x + 72 how many people who became members of the site that month were between 30 and 40 years of age? 112

Describe how the presence of possible outliers might be identified on the following. (a) histograms gap between the first bar and the rest of bars or between the last bar and the rest of bars large group of bars to the left or right of a gap higher center bar than surrounding bars gap around the center of the histogram higher far left or right bar than surrounding bars (b) dotplots large gap around the center of the data large gap between data on the far left side or the far right side and the rest of the data large groups of data to the left or right of a gap large group of data in the center of the dotplot large group of data on the left or right of the dotplot (c) stem-and-leaf displays several empty stems in the center of the stem-and-leaf display large group of data in stems on one of the far sides of the stem-and-leaf display large group of data near a gap several empty stems after stem including the lowest values or before stem including the highest values large group of data in the center stems (d) box-and-whisker plots data within the fences placed at q1 â’ 1.5(iqr) and at q3 + 1.5(iqr) data beyond the fences placed at q1 â’ 2(iqr) and at q3 + 2(iqr) data within the fences placed at q1 â’ 2(iqr) and at q3 + 2(iqr) data beyond the fences placed at q1 â’ 1.5(iqr) and at q3 + 1.5(iqr) data beyond the fences placed at q1 â’ 1(iqr) and at q3 + 1(iqr)
