Answer:
A =16
Step-by-step explanation:
Since its a Parallelogram and in a parallelogram the opposite side are always equal. AB and CD are opposite sides of a parallelogram. Hence CD =16
Answer:
Range =94
σ² = 1,141.564
Standard Deviation = 33.78703
Step-by-step explanation:
First off to find the range, we find the highest value and subtract it to the lowest value. In this situation the values are:
Highest = 99
Lowest = 5
Range = 99 - 5
Range = 94
Now to find the variance of the sample data set, we first need to find for the mean of the data.
The mean of the data with be the sum of all the numbers in the data set divided by the number of samples.
Mean =
Mean =
Mean =
Now to find the variance we simply use the formula:
σ²
σ²
σ²
σ²
Now to find the standard deviation, we take the variance and get the square root of it.
