Amelia’s teacher provides her with this spinner, which has four equal sections. Amelia has never seen this particular spinner before, and she is asked to create a theoretical probability model of one spin. In case it is a trick spinner, Amelia decides to complete 300 spins, and the results are shown in the table.

Outcome 1 2 3 4
Frequency 68 81 77 74
a. If the spinner was fair and spun 300 times, each outcome would be expected to be observed
times.
Question 2
b. Based on the data from the 300 spins, does it seem like the spinner is a fair spinner?

Yes
Yes

No
No
Question 3
c. Why or why not?

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 bsuppose 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 cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
