Answer:
15
Step-by-step explanation:
8+8 would be the doubles and that would equal 16.
Then take one away from 16 and that would equal 15
Answer:
v=9-4x
Step-by-step explanation:
V=15+6x-2x-2x3
V=15+6x-2x-6
V=15-6 +6x -2x
V=9-4x
Answer:
The mean number of cars recovered after being stolen is 267 and the standard deviation is 5.42.
Step-by-step explanation:
For each stolen car, there are only two possible outcomes. Either it is recovered, or it is not. The probability of a stolen car being recovered is independent of other stolen cars. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The standard deviation of the binomial distribution is:
In this problem, we have that:
So
The mean number of cars recovered after being stolen is 267 and the standard deviation is 5.42.
