What composition of transformations is being demonstrated in the graph below?

A)reflection across the x-axis, then reflection across the y-axis
B)Translation left 5 down, then a rotation 90 degrees clockwise around the origin.
C)Rotation 180° around the origin, then reflection across the y-axis.
D)Translation right 5 & up 1, then rotation 180 degrees around the origin.

Achemist has 200 ml of a 10% sucrose solution. she adds x ml of a 40% sucrose solution. the percent concentration, y, of the final mixture is given by the rational function: the chemist needs the concentration of the final mixture to be 30%. how many milliliters of the 40% solution should she add to the 10% solution to get this concentration?

Powerful women's group has claimed that men and women differ in attitudes about sexual discrimination. a group of 50 men (group 1) and 40 women (group 2) were asked if they thought sexual discrimination is a problem in the united states. of those sampled, 11 of the men and 19 of the women did believe that sexual discrimination is a problem. if the p-value turns out to be 0.035 (which is not the real value in this data set), then at = 0.05, you should fail to reject h0. at = 0.04, you should reject h0. at = 0.03, you should reject h0. none of these would be a correct statement.

How can you find the mean absolute deviation (mad) for this set of data?
