Answer: This quadrilateral is not a parallelogram because 1. opposite sides are not equal and 2. the right and left sides are not parallel.
Step-by-step explanation:
1. The top side is 4 units long and the bottom side is 8 units long. 4 8.
2. The side on the left has a slope of 5/13 while the side on the right has a slope of 5/9.
There are 6, you'd think there would be 8 but the answer is actually 6. A diagonal is a line segment that connects to vertices, the two vertices chosen do not count when forming the triangle, two vertices that are adjacent to that chosen vertex are NOT included when forming the diagonal. It's confusing, but I hope this helps. If you have any follow up questions I'd love to answer them.
Another name for natural numbers that I've heard is counting numbers since they are the numbers that we count with.
To find median . . . list the number in order from least to greatest
10 , 11, 12, 12 13, 15
Then cross of a number from each side until you get to the middle number or middle 2 numbers.
IF there are 2 numbers add them together and divide by 2
12 + 12 = 24
24 / 2 = 12
Your median is 12
To find mean (this is the same as average) add all the numbers to get a total.
10 + 11 + 12 + 12 + 13 + 15 = 73
Then count the number of items added . . .6
Take the total and divide by the items counted
73 / 6 = 12.1666
Your directions say to round to the nearest tenth place.
12.166 = 12.2
The coefficient of variation is 20%
The lower limit is 9 and the upper limit is 21
<h3 /><h3>How to calculate the coefficient of variation</h3>
Given the following parameters
- Sample mean "x" = 15
- standard deviation 's" = 3
The coefficient of variation is expressed as:
coefficient of variation = s/x * 100
coefficient of variation = 3/15 * 100
coefficient of variation = = 20%
Hence the coefficient of variation is 20%
The formula for the Chebyshev interval is given as:
Get the value of k using the formula below:
Get the required interval
Hence the lower limit is 9 and the upper limit is 21
