Exponential Linear Logistic Sinusoidal Which of the following is the correct regression equation for this situation? y = 4x - 160 y = -4x -160 y = 4.97(1.05)x y = 2x + 3 If the temperature is 58 degrees, how many chirps per minute can you expect from a Snowy Tree Cricket? 58 67 80 72 If you hear a cricket chirp 148 times in one minute, what would you expect the temperature to be? 77 degrees 52 degrees 432 degrees 76 degrees Make a scatterplot of the table above and identify the regression model you should use. Linear Exponential Logistic Sinusoidal Which of the following is the correct regression equation for this situation? y = 1.79x + 7.35 y = 1.79x -4.35 y = 5.8(1.3)x y = 6(1.15)x How much cola would you predict would be consumed in 1997? 15.9 billion gallons 56.3 billion gallons 64.8 billion gallons 98.5 billion gallons When was the first year that the U.S. consumed more than 200 billion gallons of cola? 1996 2016 2026 2006 Make a scatterplot of the table above and identify the regression model you should use. Linear Exponential Sinusoidal Logistic Which of the following is the correct regression equation for this situation? y = 142.08sin(.51x + 2.86) + 750.32 y = 700(1)x y = 729.04(.99)x y = 136.01sin(.02x + 1.89) + 732.50 172 minutes 550 minutes 612 minutes 596 minutes What is the minimum amount of daylight for Sydney, Australia? When did this minimum occur? June 21st July 11th May 21st December 30th Based on the last question, which of the following is NOT true of you minimum value of your data? It show that winter is during June and July. It will happen approximately 6 months from when the maximum value occurs. It will occur at approximately the same time of year each year. It shows that the shortest amount of daylight during the year will be approximately 172 minutes. Make a scatterplot of the data in your calculator and identify the regression model that should be used in this situation. Logistic Exponential Linear Sinusoidal y = 1187424.31 / (1 + 2322.09e-3.19x) y = 2322.09 / (1 + 1187424.31e-3.19x) y = 2.51(3.49)x y = 409.07x - 508.64 Which of the following is the correct regression equation for this situation? What is the most number of people this rumor will ever spread to? 2048 2322 2300 2350 On what day does the rumor reach the last person? 5 6 7 8 Which equation would represent this piecewise function for the domain -3 ≤ x ≤ -1? y = 2x y = x y = x - 1 y = 2x - 1 Which equation would represent this piecewise function for the domain 2 ≤ x ≤ 3? y = 2x - 1 y = x + 3 y = -x + 3 y = -x Which of the following is the correct domain for y = -1 in this situation? -3 ≤ x ≤ -1 0 ≤ x ≤ 2 -1 ≤ x ≤ 0 2 ≤ x ≤ 3 |
