To explain:The data represented in the complete table is a function or not.
a.

Answer to Problem 20HP
The complete table is provided below,
The data in the table represents the function.
Explanation of Solution
Given information:
The table,
Formula used:
A relation is said to be a function if every element of domain is mapped to exactly one element of range.
Calculation:
Consider the table,
Here the x represent the number that is square of a whole number.
And y represent the positive square root of the number x .
So, square root of 4 is 2, 9 is 3, 16 is 4 and 36 is 6.
Also square of 5 is 25. Therefore, complete table is.
Recall that relation is said to be a function if every element of domain is mapped to exactly one element of range.
The elements of domain are
Each member of domain is mapped to exactly one element of range. Therefore, it represent a function.
b.
To graph: The
b.

Explanation of Solution
Given information:
The data is provided below.
Graph:
When the relationship between two data sets is to be analyzed scatter plot is used.
Provided two data sets. Here the x represent the number that is square of a whole number.
And y represent the positive square root of the number x .
On the x -axis of coordinate plane denote the number from 1 to 40.
On y -axis plot denote the number from 1 to 6.
The scatter plot of the data is provided below,
Interpretation:
It is observed as the square of whole number increases its square root value also increases that is there is a strong positive linear relationship between x and y .
c.
To explain:The data represented in the complete table when the x and y coordinates are revered is a function or not.

Answer to Problem 20HP
The complete table is provided below,
The data in the table represents the function.

The table,
Formula used:
A relation is said to be a function if every element of domain is mapped to exactly one element of range.
Calculation:
Consider the table,
Here the x represent the number that is square of a whole number.
And y represent the positive square root of the number x .
Now, reverse the x and y coordinates.
So, square root of 4 is 2, 9 is 3, 16 is 4 and 36 is 6.
Also square of 5 is 25. Therefore, complete table is.
Recall that relation is said to be a function if every element of domain is mapped to exactly one element of range.
The elements of domain are
Each member of domain is mapped to exactly one element of range. Therefore, it represent a function.
d.
To graph: The scatter plot between whole number and square value of the whole number.

They are playing a game where they randomly pick a card out of the hat four times, with replacement. Amy thinks that the probability of getting exactly two aces in four picks is equal to the probability of not getting exactly two aces in four picks. Samiha disagrees. She thinks that the probability of not getting exactly two aces is greater. The sample space of possible outcomes is listed below. A represents an ace, and K represents a king.
