An equation and the steps to solve it are shown below: 3x - one over two (8x - 2) = 4 step 1: 3x - 4x + 1 = 4 step 2: x + 1 = 4 step 3: x + 1 - 1 = 4 - 1 step 4: x = 3 which step was the error made and why?

F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)

Using the figure below, select the two pairs of alternate interior angles.a: point 1 and point 4 b : point 2 and point 3 c: point 6 and point 6d: point 5 and point 7

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.
