Thor and Zeus strike with their hammers. The higher they raise their hammers before they strike, the louder the sound of the strike. The following equation gives the loudness of Thor's strike (in decibels) as a function of the height from which he strikes (in centimeters). S = 3h+25 The graph of the loudness of Zeus's strike (in decibels) as a function of the height from which he strikes (in centimeters) is shown below. Whose loudness increases more per additional centimeter of height? Choose 1 A. Thor's B. Zeus's C. The increase in loudness per centimeter is the same for both Whose strike is louder when he strikes from a height of 40 centimeters? Choose 1 A. Thor's B. Zeus's C. The strikes are equally loud

Read the equations in the table below. then drag a description of the situation and a table to represent each equation. indicate whether each of the relationships is proportional or non-proportional.

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?
