Van is studying the effects of an indoor pool temperature on the number of swimmers. He made
this histogram to display his data.
Which statement is best supported by the data?
A:The pool has the least number of swimmers
O when the temperature is between 71 and
75°F.
B:The temperature of the pool doesn't
influence the numbers of swimmers.
C:The pool has the greatest number of
swimmers when its temperature is between
81 and 85°F.
D:More people swim when the temperature of
the pool is the warmest.

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 > ?
