A research team is testing a product that will minimize wrinkles among women. Volunteers in the age group of 40 to 45 are included in the research. The research team gives a bottle of the solution to one group and a similar bottle of solution with no ingredients intended to lessen wrinkles to the other group. In the description of the above situation, determine the control group.
a. The group that received the bottle of solution is the experimental group.
b. The group that received the bottle of solution that did not contain the ingredients that are meant to lessen wrinkles is the experimental group.
c. Both the groups are experimental groups.
d. Neither group is an experimental group.

The distance, y, in centimeters, of an ant from a hole in the tree for a certain amount of time, x, in seconds, is shown in the graph: a graph titled motion of ant is shown. the graph shows time in seconds on the x-axis and the distance from hole in centimeters on the y-axis. the scale on the x-axis is shown from 0 to 6 at increments of 1, and the scale on the y-axis is shown from 0 to 12 at increments of 2. the graph has 3 straight lines. the first line is labeled p and joins ordered pairs 0, 0 and 2, 6. the second line is labeled q and joins ordered pairs 2, 6 and 3, 6. the third line is labeled r and joins ordered pairs 3, 6 and 5, 0.part a: is the graph linear or nonlinear? explain your answer. (2 points)part b: in which segments is the graph increasing, decreasing, and constant? (3 points)part c: in your own words, describe the motion of the ant, as shown on the graph. (5 points)
