Answer:
99% CI:
Step-by-step explanation:
We have to calculate a 99%CI for the difference of means for the vegan and the omnivore.
First, we have to estimate the standard deviation
The MSE can be calculated as
The weighted sample size nh can be calculated as
The standard deviation then becomes
The z-value for a 99% confidence interval is z=2.58.
The difference between means is
Then the confidence interval can be constructed as
Answer:
70 degrees

Answer:
<h2>There remains 7/6 of pie.</h2>
Step-by-step explanation:
Givens
The remaining parts are 1/3 of one pie and 5/6 of the other pie.
To find how much pie is remaining, we just need to sum those fractions.
Therefore, there remains 7/6 of pie. They ate just 1/6.
Answer:A rational number can be written as a fraction of two integers. √23 is irrational because we do not know what the square root of 23 is in terms of integers in a fraction. 104.42 is rational because it can be expressed as 10442/100 . We can express it as this because.
Step-by-step explanation:
Subtract 60 on both sides to get -40.
You are left with 40x=-40
Divide both sides by 40 to leave x by itself.
You get x=-1.
