Consider that 80 households purchased a television. The customers were surveyed. Results found that 64 households were satisfied with their purchase and 16 households were dissatisfied. Suppose 2 households are randomly selected from the 80 households. Find the probability that both households are dissatisfied with their purchase. Round to four decimal places. (2 points) Define A = first household selected is dissatisfied Define B = second household selected is dissatisfied.

Step-by-step explanation:

There are in total 80 households who purchased a television.

From the 80 households, 2 households can be chosen in way.

Total 16 households were dissatisfied, hence, from these 16 households 2 households can be chosen in ways.

Hence the required probability is  .

A = first household selected is dissatisfied = the first household is to be chosen from the 16 households. There will be in total 16 possibilities.

B = second household selected is dissatisfied = 16 possibilities if none of the dissatisfied household has been chosen or 15 possibilities if one of these household is already been chosen.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
