Answer:
5.9+z=−9
Step 1: Simplify both sides of the equation.
z+5.9=−9
Step 2: Subtract 5.9 from both sides.
z+5.9−5.9=−9−5.9
z=−14.9
Answer:
z=−14.9

Answer:
15
Step-by-step explanation:
So, between 14 and 15 would be where 14 5/6 is at. But, 14 3/6 would be directly in the middle of the two. Since 14 5/6 is greater than 14 3/6, it would round up to 15 instead of rounding down to 14.
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.
