- Sum of Angles: 180(n - 2)°
Step-by-step explanation:
<u>Step 1: Define</u>
We are given a 5-sided polygon (irregular pentagon)
n = 5
<u>Step 2: Find Sum</u>
- Substitute in <em>n</em> [Sum of Angles]: 180(5 - 2)°
- (Parenthesis) Subtract: 180(3)°
- Multiply: 540°
Answer:
x = 3
Step-by-step explanation:
From the given parallelogram;
m<XWC = m<XYC
Given
m<XWC = 2x+5
m<XYC = 3x+2
Equate
2x+5 = 3x+2
2x - 3x = 2 - 5
-x = -3
x = 3
Hence the value of x is 3
Answer:
The margin of error for a 99% confidence interval for the population mean is 1.8025.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
In this problem:
So
The margin of error for a 99% confidence interval for the population mean is 1.8025.
