a)y=(x-3)^2+15

b)y=(x+3)(x-3)+5

c)y=(x-3)^2+23

d)y=(x-3)^2+5

If 20% of a number is 35, what is 50% of that number?

What can you determine about the solutions of this system

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.
