The following data are based on a survey taken by a consumer research firm.In this table x = number of televisions in household
and % = percentages of U.S. households x 0 1 2 3 4 5 or more % 3% 11% 28% 39% 12% 7% What is the probability that a household selected at random has less than 3 televisions? Select one: a. 0.81 b. 0.39 c. 0.42 d. 0.58
Probability is the study of determining the chances of an event being successful or not. To determine the probability of, say, 5 events happening, you would have to add their individual probabilities. For the probability of household having less than 3 televisions, you add the data for 2, 1 and 0 televisions.
Total Probability = 3% + 11% + 28% = 42% (or 0.42 if in decimal form)
Answer is parallel lines Reason - same slope (3x) and different y intercept means they will be parallel lines because their slope is the same but they will cross the y axis at different points.
I changed the first equation to y intercept form y = 3x - 10 to match the other equation y = 3x - 6
doesn't belong with the other three because it is irrational number
