Answer:
10.94
Step-by-step explanation:
The standard deviation is calculated by using the following formula:
This means that N is the total number of cases you want to take into account, times the sum of x at the ith position - x squared.
In other words, the standard deviation in your example implies the following:
26 is the first value, so i = 1, 34 is the second value, so i = 2, 18 where i = 3, and so on and so forth, until you reach the end, which is 6 (so the initial value is 1 and the last one is 6).
You're doing a sum over an iteration of all the numbers in your sample.
So applying the sum of all of the numbers, it gives us the following:
The sum of all of the numbers in your sample is equal to 119.6.
Substitute into the equation once again:
Where the square root of 119.6 is 10.93617...
Rounded to two decimal places: 10.94
For this case we have the following conversion of units:
1 lb = 453.59 g
We apply the conversion of units to the weight of the package.
We have then:
(8) * (453.59) = 3628.72 g
Answer:
the weight in grams is:
3628.72 g.
you can use the following conversion factor:
1 lb = 453.59 g
For this, we will be using Triangle Angle Sum Theorem (all interior angles in a triangle add up to 180°) for Triangle BCD. Since Angle CBD and BDC are congruent to each other and Angle BDA, we can solve for those two angles to get that angle. Our equation will look like this: 
Firstly, subtract 35 on both sides of the equation: 
Next, divide both sides by 2 and your answer will be 72.5 = x.
Since Angle CBD and BDC are 72.5°, this means that Angle BDA is 72.5° as well.
I think this is the Transitive postulate of equality.
Personally I can't see much point in giving labels to these equalities.
A) There was no change in the number of students on honor roll from one year to the next. This is noticeable because 200/1000 = .2 just as 20%/100% = .2 or 20/100 = .2. So there never was a change!
