Step-by-step explanation:
10 1/2
10.5 = 10 5/10
but 5/10 can be simplified to 1/2
the answer is 10 1/2
Answer:
a) Mean(x) = 0.40
b) Variance(x) = 0.24
Step-by-step explanation:
From the information given, the process is Bernoulli process, since the team can run or pass the ball into the end zone to score two points only. We are not told the number of times. Thus, <em>n </em>is unknown. That is, we are not told how many times the team successfully pass the ball into the end zone.
By Bernoulli process, the mean and variance are given as follow:
Mean = p
Variance = pq. This is the same as p(1-p)
Where p is the probability that this play is successful and q is the probability that this play is not successful.
