Answer: sigma is used for measuring Population Standard Deviation.
Step-by-step explanation:
The lower case Greek letter 'sigma' is denoted by the symbol ( 
).
This symbol indicates the Population Standard Deviation of the data. Standard deviation means how much variation or dispersion is there in our data. Squaring of standard deviation gives us Variance which is denoted by the symbol 
.
Formula for Population Standard deviation ( ) is = 
,
where 
= each value from our list of data
= Population mean of data
N = Number of observations in our data
Standard deviation can never be negative and it is very much sensitive to outliers in our data.
Hello from MrBillDoesMath!
Answer:
96 degrees
Discussion:
The base angles of an isosceles triangle are equal and a triangle has 180 degrees. In our case this means that
42 + 42 + (measure of vertex angle) = 180
84 + (measure of vertex angle) = 180 => (subtract 84 from both sides)
84 - 84 + (measure of vertex angle) = 180- 84 =>
(measure of vertex angle) = 180- 84 = 96
Thank you,

Answer:
Divide the measurement by 36 to determine the number of yards needed. For example, if the pattern pieces cover an area of floor equal to 72 inches in length, then divide 72 by 36 to get 2, the number of yards of 54-inch wide fabric needed for the ottoman.
10 is the base. If you get stuck on anymore problems like this you can tell which one is the base by looking where the exponent is in the problem. Hope this helps!!
