Which should be used to describe the average of the data? _____________ 11. If the temperature is -15 degrees Celsius, what are the degrees in Fahrenheit? First pick the correct formula: C = 5/9(F – 32) or F = 9/5C + 32 a – 3 + 2a + 5 11.You need 2/3 of the class to complete their Achieve articles. If there are 27 students, how many have completed their articles? 12.Each ticket cost $12 and you sold $2,820 worth. Write an equation to find the number of t tickets sold. 13.Find the graph that represents the equation. y = 2(x – 2) Hint: One way to do this kind of problem is to do the following: 1. Make a t-table 2. substitute for x any 2 numbers that are not consecutive (next to each other); Example: 0, 2, or -1, 1, …Whatever you choose you need to be able to graph the ordered pairs. 3. Take the ordered pairs and graph them. 4. Whichever graph they match is the correct answer.
