Refer to Copier maintenance Problem 1.20. The users of the copiers are either training institutions that use a small model, or business firms that use a large, commercial modeL An analyst at Tri-City wishes to fit a regression model including both number of copiers serviced (XI) and type of copier (X2 ) as predictor variables and estimate the effect of copier model (S-small, L-large) on number of minutes spent on the service call. Records show that the models serviced in the 45 calls were

Jessica and martha each have a bag of cookies with unequal quantities. they have 30 cookies total between the two of them. each of them ate 6 cookies from their bag. the product of the number of cookies left in each bag is not more than 80. how many more cookies will jessica have martha? if x represents the number of cookies jessica started with, complete the statements below. the inequality that describes the relationship between the number of cookies each one of them has is x^2 - x +224 > = 0.jessica has at least cookies more than martha.

Write the equation for the parabola that has x− intercepts (−2,0) and (4,0) and y− intercept (0,4).
