Using the mean <u>formula and it's interpretation</u>, it is found that:
1. The mean is 7.52.
2. If we were to give this quiz to more and more students, the mean score for these students would approach 7.52.
The mean of a discrete distribution is given by the <u>sum of each outcome divided by it's respective probability</u>.
Hence, in this problem, according to the <u>distribution given</u>, the mean is:

The mean is 7.52.
The <em>interpretation </em>is that over many trials, the mean would approach 7.52.

Answer:
cos 240 deg = -1/2 and sin 240 = - root(3)/2
Step-by-step explanation:
if cos 60° = 1/2 and sin 60º = root 3/2 find cos 240° and sin 240".
we know that cos 240 = cos (60 + 180) = - cos 60 = - 1/2
cosine is negative when the angle is in the 3rd quadrant
sin 240 = sin (60 + 180) = - root(3) /2
sine is also negative in the 3rd quadrant.
