Listed below are the numbers of cricket chirps in 1 minute and the corresponding temperatures in °F. Find the regression equation, letting chirps in 1 minute be the independent (x) variable. Find the best predicted temperature at a time when a cricket chirps 3000 times in 1 minute, using the regression equation. What is wrong with this predicted temperature? Chirps in 1 min Temperature (°F) 792 1056 991 1177 1097 939 823 905 67.2 86.6 83.5 93.6 89.5 73.5 72.5 70.7 The regression equation is y=+x. (Round the y-intercept to one decimal place as needed. Round the slope to four decimal places as needed.)

For the given functions f(x) = x +4 and g(x) = 2x+2, find the following. (a) (fo g)(2) (b) (g o f)( - 3) (c) (f o f)(1) (d) (g o g)(- 8) (a) (fo g)(2) = (Simplify your answer.)

The following data is the number of tickets sold and the jackpot value for the Mega Millions lottery. The jackpot value is in millions of dollars and the number of tickets sold is in millions. Jackpot value 334 127 300 227 202 180 164 145 255 Number of tickets sold 54 16 41 27 23 18 18 16 26 r= 0.947 tickets sold -10.87 +0.17 (jackpot value) Which is the independent variable and which is the dependent variable? X= independent variable = Y= dependent variable Interpret ². Interpret the slope. Predict the number of tickets sold when the jackpot value is 500 million dollars. Would you feel comfortable using the model for this value? Why or why not.
