Amir and Edward are twins, They want to invite their friends to celebrate birthday party at a bowling alley. They have a budget of $200 to plan their party. The party room at the bowling alley costs $55.99 to rent and includes a free birthday cake. The bowling alley charges each person $5.50 to bowl and pair of bowling shoes. Amir writes an equation that represents the cost of their birthday party, Edward writes an inequality. Both use p to represent the number of people that can attend. A. Write an equation Amir used and an inequality Edward used to represent the cost of their birthday party. Each brother believes that their statement best represents the situation. Amir thinks that his equation is the best representation for the situation. Edward argues that his inequality is the best representation for the situation. B. Which brother's statement best represents the situation? Explain.

1. the manager of collins import autos believes the number of cars sold in a day (q) depends on two factors: (1) the number of hours the dealership is open (h) and (2) the number of salespersons working that day (s). after collecting data for two months (53 days), the manager estimates the following log-linear model: q 4 equation 1 a. explain, how to transform the log-linear model into linear form that can be estimated using multiple regression analysis. the computer output for the multiple regression analysis is shown below: q4 table b. how do you interpret coefficients b and c? if the dealership increases the number of salespersons by 20%, what will be the percentage increase in daily sales? c. test the overall model for statistical significance at the 5% significance level. d. what percent of the total variation in daily auto sales is explained by this equation? what could you suggest to increase this percentage? e. test the intercept for statistical significance at the 5% level of significance. if h and s both equal 0, are sales expected to be 0? explain why or why not? f. test the estimated coefficient b for statistical significance. if the dealership decreases its hours of operation by 10%, what is the expected impact on daily sales?
