Answer:
74
Explanation:
28+2*(24-1)= 74
Given:- There are 28 seats in the front row of theater
Number of rows=24
To find:- The number of seats in the last row.
Use the formula to find the 24th term of this sequence.
Also each successive row has two more seats. This difference is same for the whole theater.
So, this forms an arithmetic sequence.
a1=21
D=2
We need to find number of seats in 24th row; which is given by a24
We use the formula for it
Based on the payoffs and the probabilities given, we can calculate the mean to be <u>0.8 shots made. </u>
<h3>What is the mean?</h3>The mean in this scenario will be a weighted average of the probabilities that a number of shots will be made.
The mean will be:
<em>= ∑ (Number of shots x Probability of number of shots)</em>
= (0 x 0.36) + (1 x 0.48) + (2 x 0.16)
= 0.8 shots
In conclusion, the mean is 0.8 shots.
