explain what the standard deviation is for a set of data.
Answer:
The Standard Deviation is a measure of how spread out numbers are. You might like to read this simpler page on Standard Deviation first. But here we explain the formulas. The symbol for Standard Deviation is σ (the Greek letter sigma)
Answer:
Shows the variation in data(average of all means of the data)
Step-by-step explanation:
Ok,so, if for example, data is grouped close together, then the standard deviation will be small, if the data is more spread out then the deviation will be larger. How to tell?
Well, it all depends on the distance away from the mean. The center is usally where the mean is. How far from the mean is your data?
How to calculate?
-There are multiple equations you can use depending on your data.
If you are analyzing data which represents a larger set, use sample standard deviation, if you collect data from every member of the set, then use population standard deviation.
First, calculate the mean(average) of each set of data.
Then subtract the deviance(subtract mean from each number -/+)
Square each deviation
add up all squared deviations
Divide the number by one less than the number of items in the data. (If it was 5 it would be 4.)
Then calculate the square root of the resting value.
we need standard units to measure the physical quantity

How does the graph below change between point A and point B?
∠A and ∠B are supplementary. The measure of ∠A is 87°.
What is the measure of ∠B?
Enter your answer in the box.
Point theif = ban
Answer: The answer is BCD is 77 degree
Step-by-step explanation:
Answer:
∠B = 93°
Step-by-step explanation:
Supplementary angles are such pairs that sum up to 180°. In this case, we are given that ∠A and ∠B are supplementary. This means that the sum of ∠A and ∠B is 180°.
⇒ ∠A + ∠B = 180°
⇒ 87 + ∠B = 180°
⇒ ∠B = 180 - 87
⇒ ∠B = 93°

Which situation most directly illustrates a possible outcome of a fiscal policy?
A. A corporation decides a to expand its operation to several new states.
B. The amount of federal money available to support education decreases.
C. Employees at a company are forced to take a pay cut while executives do not.
D. The value of the dollar goes down relative to a foreign currency's value.
Answer: B. The amount of federal money available to support education decreases.
Step-by-step explanation:
The Fiscal policy of a Government relates to the spending and taxation policies of that Government in an effort to control the direction of the Economy.
Normally there are two types of Fiscal Policy: Expansionary and Contractionary. Expansionary fiscal policy works by the Government increasing spending and/ or cutting taxes so that consumers in the economy have more money.
Contractionary policy is the opposite and involves Government spending reducing and/ or taxes increasing. Reducing the amount of Federal money available for education is a possible product of Contractionary fiscal policy.

Given the costs for several of the same grocery items in two countries find the rate of the total cost for these item in the united kingdom to that of the total cost of items in Canada
Rates are used to compare related quantities such as costs of items in two countries
How to determine the ratioThe question is incomplete;
So, I will give a general explanation on how to calculate the rate.
Assume that the costs are:
United Kingdom = 500
Canada = 750
The ratio would be:
Ratio = United Kingdom : Canada
So, we have:
Ratio = 500 : 750
Simplify
Ratio = 2 : 3
Express as rate
Rate = 2/3
Using the assumed values, the rate of the total cost for items in the United Kingdom to that of the total cost of items in Canada is 2/3

Lena is reading a book. The product of the two page numbers facing each other is 5852. What is the sum of the two pages?
Answer:
first page is 12, and the facing page is 13.
Step-by-step explanation:
The pages are facing each other, so they are consecutive numbers:
Let x = the first page number
y = the second page number
The second page number is just 1 more than the first, because they are consecutive numbers:
x+1 = y
We also know that the products of the numbers is equal to 156:
xy = 5852
Now we will sub y = x+1 into the second equation:
x(x+1) = 5852
x^2 + x = 5852
x^2 + x - 5852 = 0
Factoring (or using the quadratic formula) gives us:
(x+13)(x-12) = 0
x = - 13, or x = 12.
A page number can't be negative, so we will choose x=12.
This means that the second page must be page 13.
Based on the given segment lengths, determine whether the segments can form a triangle.
11.5,10.5, 6.1
9.5, 3.5, 4.5
8, 6.7, 1
8, 6.7, 9.8
5, 6, 8
9.5, 7.5, 8.5
For 3 sides to form a triangle two sides added together need to be greater then the 3rd side. You need to check all 3 combinations:
1. 11.5 + 10.5 = 22, 22> 6.1
11.5 + 6.1 = 17.6 17.6 > 10.5
10.5 + 6.1 = 16.6, 16.6 > 11.5
This one can make a triangle.
2. 9.5 + 3.5 > 4.5
9.5 + 4.5 > 3.5
4.5 + 3.5 < 9.5
Cannot make a triangle.
3. 8 + 6.7 > 1
6.7 + 1 < 8
Cannot make a triangle.
4. Can make a triangle
5. Can
6. Can
Can form triangle : 11.5,10.5, 6.1 & 8, 6.7, 9.8 & 5, 6, 8 & 9.5, 7.5, 8.5
Can not form triangle : 9.5, 3.5, 4.5 & 8, 6.7, 1
What is triangle inequality theorem ?
If sum of any two line segments is greater than the third line segment, then we can say that, they can make a triangle.
How to know which sets form triangle ?1st problem,
The given line segments are 11.5, 10.5, 6.1
Now, 11.5+10.5 = 22 > 6.1
10.5+6.1 = 16.6 > 11.5
11.5+6.1 = 17.6 > 10.5
So, this three segments can form triangle.
2nd problem,
The given line segments are 9.5, 3.5, 4.5
Now, 9.5+3.5 = 13 > 4.5
9.5+4.5 = 14 > 3.5
4.5+3.5 = 8 < 9.5
Here triangle inequality rule isn't applicable.
So, it can not form triangle.
3rd problem,
The given line segments are 8, 6.7, 1
Now, 8+6.7 = 14.7 > 1
8+1 = 9 > 6.7
6.7+1 =7.7 < 8
Here triangle inequality rule isn't applicable.
So, it can not form triangle.
4th problem,
The given line segments are 8, 6.7, 9.8
Now, 8+6.7 = 14.7 > 9.8
8+9.8 = 17.8 > 6.7
6.7+9.8 = 16.5 > 8
So, this three segments can form triangle.
5th problem,
The given line segments are 5, 6, 8
Now, 5+6 = 11>8
5+8 = 13 > 6
6+8 = 14 > 5
So, this three segments can form triangle.
6th problem,
The given line segments are 9.5, 7.5, 8.5
Now, 9.5+7.5 = 17 > 8.5
9.5+8.5 = 18 > 7.5
7.5+8.5 = 16 > 9.5
So, this three segments can form triangle.

What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9. Based on the basic value of its digits, different types of number systems exist.
The natural number now includes all positive integers from 1 to infinity.
Natural numbers include 1, 2, 3, 4, 5, and so on.
Whole numbers now include all positive integers from 0 to infinity.
The whole number is 0, 1, 2, 3, 4, 5, and so on.
As can be seen, every natural number are the whole number
