The distance, y, in miles, traveled by a car for a certain amount of time, x, in hours, is shown in the graph below:

a graph titled motion of car is shown with time in hours labeled on x-axis and distance from starting point in miles labeled on y-axis. the scale on the x-axis shows the numbers 1, 2, 3, 4, 5, 6, and the scale on the y-axis shows the numbers 0, 14, 28, 42, 56, 70, 84. there are three straight lines in the graph. the first line joins ordered pair 0, 0 with 3, 42. the second straight line joins 3,42 and 4,42 and the third straight line joins ordered pair 4,42 with the ordered pair 5,56.

which of the following best describes the motion of the car shown?

it travels for 2 hours, then stops for 1 hour, and finally travels again for 5 hours.
it travels for 3 hours, then stops for 1 hour, and finally travels again for 1 hour.
it travels for 3 hours, then stops for 4 hours, and finally travels again for 5 hours.
it travels for 2 hours, then stops for 2 hours, and finally travels again for 1 hour.

Cindy uses 1-inch cubes to find the volume of a jewelry box shaped like a rectangular prism. she uses 780 cubes to completely fill the jewelry box with no gaps or overlaps. if the jewelry box is 13 inches long and 5 inches wide, how tall is cindy’s jewelry box?

In a test for esp (extrasensory perception), the experimenter looks at cards that are hidden from the subject. each card contains either a star, a circle, a wave, a cross or a square.(five shapes) as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. when the esp study described above discovers a subject whose performance appears to be better than guessing, the study continues at greater length. the experimenter looks at many cards bearing one of five shapes (star, square, circle, wave, and cross) in an order determined by random numbers. the subject cannot see the experimenter as he looks at each card in turn, in order to avoid any possible nonverbal clues. the answers of a subject who does not have esp should be independent observations, each with probability 1/5 of success. we record 1000 attempts. which of the following assumptions must be met in order to solve this problem? it's reasonable to assume normality 0.8(1000), 0.2(1000)%30 approximately normal 0.8(1000), 0.2(1000)% 10 approximately normal srs it is reasonable to assume the total number of cards is over 10,000 it is reasonable to assume the total number of cards is over 1000
