Two lines, c and d, are represented by the following equations: line c: y = x + 5 line d: y = −2x − 1 which of the following options shows the solution to the system of equations and explains why? select one: a. (−2, 3), because the point does not lie on any axis b. (−2, 3), because both lines pass through this point c. (−2, 3), because one of the lines passes through this point d. (−2, 3), because the point lies between the two axes

According to a study conducted in 2015, 18% of shoppers said that they prefer to buy generic instead of name-brand products. suppose that in a recent sample of 1500 shoppers, 315 stated that they prefer to buy generic instead of name-brand products. at a 5% significance level, can you conclude that the proportion of all shoppers who currently prefer to buy generic instead of name-brand products is higher than .18? use both the p-value and the critical-value approaches.
