The isosceles triangle has a perimeter of 7.5 m. Which equation can be used to find the value of x if the
shortest side, y, measures 2.1 m?
O 2x - 2.1=7.5
O 4.2 + y=7.5
O y-4.2 = 7.5
O 2.1 + 2 x = 7.5

The base of a triangle exceeds the height by 9 inches. if the area is 180 square inches, find the length of the base and the height of the triangle.

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.
