Will be mark brainless The number of hours that 20 people spent watching television per day, in relation to age, is graphed. This quadratic equation represents the
model for the set of data.

y = 0.00412 - 0.3141 +7.5

Based on the model, approximately how much time does an 18-year-old spend watching television each day?

A. 2 hours

B. 0.5 hour

C. 7.5 hours

D. 3 hours

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
