Answer:
Step-by-step explanation:
All triangles have 180 degrees when the 3 angles are added together.
The angles are x , 33, and the small square is 90
So you have x + 33 + 90 = 180 Combine
x + 123 = 180 Subtract 123 from both sides.
x = 180 - 123
x = 57
<span>miles per gallon uses ratios. Say your car was doing 80 miles for 4 hours. You would have the ratio 80;4 and you need to find the miles per 1 hour</span>
For location 1:Probability of success = 0.5
Probability of failure = 1 - Probability of success = 0.5
Expected Value for Location 1 will be:
For location 2:Probability of success = 0.75
Probability of failure = 1 - 0.75 = 0.25
So, expected value for Location 2 will be:
The expected value from Location 2 is larger than Location 1, so Location 2 must be used to open up a bakery.
I'm guessing it's about 75 restaurants that have Hawaiian pizza on their menu. I just multiplied 7.5 by 10 because there are a 100 restaurants overall.
Answer:
There is 95% confidence that the population proportion of people from Vermont who exercised for at least 30 minutes a day 3 days a week is between 55.9% and 74.7%.
Step-by-step explanation:
We have to answer the population proportion for Vermont.
We can only do it by a confidence interval, as we only have information from a sample.
This sample, of size n=100, has a proportion p=0.653.
The degrees of freedom are:
We will calculate a 95% confidence interval, which for df=99 has a critical value of t of t=1.984.
The margin of error can be calculated as:
Then, the upper and lower bounds of the confidence interval are:
Then, we can say that there is 95% confidence that the population proportion of people from Vermont who exercised for at least 30 minutes a day 3 days a week is between 55.9% and 74.7%.
