Answer:
The standard deviation of this distribution is 0.8850.
Step-by-step explanation:
For each U.S. mortgage in the sample, there are only two possible outcomes. Either it is delinquent, or it is not. The probabilities of each mortgages being delinquent are independent from one another. 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 standard deviation of the binomial distribution is:
11% of U.S. mortgages were delinquent last year.
This means that
A random sample of eight mortgages was selected. What is standard deviation of this distribution?
This is when
The standard deviation of this distribution is 0.8850.
Hi!
First, find the total percent of vehicles with at least 3 people.
15% + 7% + 3% = 25%
Now find 25% of 420
Set up a proportion and cross multiply to solve.
25 * 420 = 10500
10500/100 = 105
The answer is 105 vehicles contained at least 3 people.
Hope this helped! :)

Answer:
Step-by-step explanation:
We know that ∠A and ∠B are the same exact length. Since one of the angles is given to us in an exact length, we can set the measures equal to each other.
Let’s solve for x.
