The absolute value function is one-to-one, while the greatest integer function is many-to-one.

a. true
b. false

Option B that is false.

Step-by-step explanation:

The above statement is false because

Absolute value function is not one-one

For example:

|x|=x  and |-x|=x

We are getting one vale at two different points.

And greatest integer function is many to one that is correct because

it will consider only the integer part

for example:

[1.05]=1 ,[1.02]=1 ,[1.06]=1 ,[1.08]=1

Hence, many to one

Nut one if false one is true

Hence, entirely it would be a false statement

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
