Problem Statement
We are asked to find the critical t-value for a confidence level of 80% and sample size of 17.
Method
To solve this, we simply need to do two things:
1. Calculate the degrees of freedom:
Answer:
The mean would be 4
Step-By-Step Explanation For Finding The Mean:
1. Add all of the numbers together
If you added correctly you should have got 24
2. Count the amount of numbers you added
If you counted correctly you should have counted 6 number
3. Take 6 and 24, then divide them
If you did this correctly you should have gotten 4
Just remember that the mean is a set of numbers and their sum divided by the number of terms you just added.
One gallon costs $1.88. To find the cost of seven gallons, you would multiply this price by seven.
1.88 x 7 = $13.16, which is answer D
A triangle has 3 sides, the total interior angels sum to 180 degrees.
A square has 4 sides, the total interior angels sum to 360 degrees.
A pentagon has 5 sides, the total interior angels sum to 540 degrees.
Do you see a trend?
Answer:
The (s) sum of interior angles equals the (n) number of sides, minus 2, times 180.
This is written as
s = (n - 2) * 180
If we put in 900 for s, we get
900 = (n - 2) * 180
5 = n - 2
n = 7
A polygon with 7 sides is called a Heptagon.
