Data were gathered on how high dolphins jump from the surface of the water based on body length and graphed on a scatterplot. (10 points) Scatterplot with the x-axis labeled dolphin body length and y-axis labeled height of jump. Points plotted are 5.5 and 15, 6 and 16, 6.6 and 17.5, 7.3 and 17, 7.5 and 18.2, 8.3 and 18.5, 8.3 and 19, 8.5 and 19.1, and 9.8 and 25.

Part A: Interpret the scatterplot. Comment on the association, form, strength, and outliers. (5 points)
Part B: The correlation coefficient of the data is r = 0.91. Does this correlation make sense based on the interpretation in part A? Explain. (5 points)

Abus travels 36 miles in 45 minutes. enter the number of miles the bus travels in 60 minutes at this rate.

Interpret the following expression (5y^2-7)^3/(2y)^2

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α. part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part b suppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i. e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part c now try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
