If you add the same constant to each element of a sample then the mean of this collection of values will be the mean of the original sample plus the constant.
If you multiply each element of a sample by a constant then the mean of this collection of values will be the mean of the original sample multiplied by the constant.

How does adding it subtracting a constant amount by each value in a set of data affect the mean?
When adding and subtracting a constant amount means that that amount will increase. The amount will increase dew to adding each number.
You toss three coins What is the probability of the event 3 Heads appear?
Since each event is independent (heads in one coin does not affect the probability of the other two coin flips), the multiplication rule applies: 1/2 x 1/2 x 1/2 = 1/8 or 0.125. So we can say the probability is 12.5%.
What is the theoretical probability of randomly selecting a 3 child family with 3 girls?
The gender of children is not a constant. It depends on the parental predispositions - mainly on the father's genes but apparently the mother's age can also affect the gender. The details of these influences are not understood well enough to develop an accurate model. If you make the simplistic but unjustified assumption that both genders are equally likely, the answer is 1/8.
How does the outlier affect the mean median mode?
An outlier can increase or decrease the mean and median It usually doesn't affect the mode
Does outliers affects data?
No. Outliers are part of the data and do not affect them. They will, however, affect statistics based on the data and inferences based on the data.
Definition of commutative property?
The order in which the addends (in addition) or multiplicands (in multiplication) does not affect the answer. If symbolic form: a + b = b + a or a * b = b * a
What is inverse operation?
An inverse operation undoes the effect of another operation. For example, addition is the inverse operation of subtraction, and multiplication is the inverse operation of division. Applying an operation and its inverse leaves you with the original value.
What is the deffinition of commutative?
Assuming you mean definition, commutative is a property of an operation such that the order of the operands does not affect the result. Thus for addition, A + B = B + A. Multiplication of numbers is also commutative but multiplication of matrices is not. Subtraction and division are not commutative.
What property of multiplication states that the order in which two numbers are multiplied does not affect the product?
Commutative Property of Multiplication
What is an of associative property?
It is the property of operations such as addition or multiplication which state that the order in which the operations are carried out does not affect the result. That is, (A + B) + C = A + (B + C) and so, without ambiguity, you can write these as A + B + C.
What does the commutative property mean?
The commutative property states that changing the order of operands in a binary operation does not affect the result. More simply, and using more familiar terms: for addition, it means that A + B = B + A or for multiplication, A * B = B *A Subtraction and division are not commutative, nor is matrix multiplication.
How does length of spring coil affect the force constant?
The force constant is unaffected; It is a constant.
How does water affect erosion?
constant flowing affect erosion
What is commutativity property?
something like 5x4=4x5.
Is this true or false In arithmetic the grouping of the addends or factors does not affect the sum or product?
True.
Does studying multiplication affect math scores?
the answer is no for now, try back later
Does solar constant affect temperature?
ok
