Answer:
x = 9
Step-by-step explanation:
Step 1: Look at graph
You can see that both ∠B's are the same. Therefore, both side lengths AD and CD are the same
Step 2: Set equations equal to each other
3x = 2x + 9
Step 3: Solve
x = 9
And we have our answer!
For this equation, you'll need to set x to 0 and solve from there.
First step is to solve the parentheses and then square the answer. Your equation will look like this:
Next, you will multiply -16 and 1, and then add the product of that by 21. Your answer will be
In short, the ball is thrown from 5 feet above ground.
2. just do inverse transformation to get pre-image. simply do T(4,-3) to given vertices.
you'll get A(-1,1)B(7,1)C(7,-2)D(-1,-2)

10.option 1 and 4
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.
