A biologist gathered data on the length, in millimeters (mm), and the mass, in grams (g), for 11 bullfrogs. The data are shown on the plot below. PLOT 1 550- 500 450 Mass (g) 400- 350 300- 250 200- 120 130 140 150 160 170 180 Length (mm) The biologist used the data in the table to calculate the line of regression for predicting mass from length. The line of regression is represented by y = -546 + 6.086x. Which of the following statements is true? A. The slope is -546, which means that a bullfrog's predicted length can be found by subtracting 546 from its mass. B. The slope is -546, which means that a bullfrog's predicted mass can be found by subtracting 546 from its length. C. The slope is 6.086, which means that for every increase of 1 mm in length, the predicted mass increases 6.086 grams. D. The slope is 6.086, which means that for every increase of 6.086 mm in length, the predicted mass increases 1 gram.19. The measure of one of the two base angles of an isosceles triangle is 42 .

Studies have shown that foods rich in compounds known as flavonoids help lower blood pressure Researchers conducted a study to investigate whether there was a greater reduction in blood pressure for people who consumed dark chocolate, which contains flavonoids, than people who consumed white chocolate, which does not contain flavonoids. Twenty-five healthy adults agreed to participate in this study. 13 were randomly assigned to the dark chocolate group and the rest were assigned to the white chocolate group. All participants had their blood pressure recorded before adding chocolate to their daily diets and again 30 days after adding chocolate to their daily diets. Dark Chocolate - White Chocolate - -12 -10 -8 -6 - 4 -2 0 2 4 6 8 10 12 16 Reduction in Blood Pressure (mmHg) Which of the following statements is true? A. The median reduction in blood pressure is greater for those that consumed dark chocolate than those that consumed white chocolate. B. The range of reduction in blood pressure is greater for those that consumed dark chocolate than those that consumed white chocolate. C. The mean reduction in blood pressure is greater for those that consumed white chocolate than dark chocolate. D. The median reduction in blood pressure is less for those that consumed dark chocolate than those that consumed white chocolate.21.
