Answer:
y = 1/3a
Step-by-step explanation:
y = ka
1 = 3k
k = 1/3
Confirm constant: (4-1)/(12-3) = 3/9 = 1/3
1 = 3(1/3) + b
1 = 1 + b
b = 0
y = 1/3x or 1/3a
If both variables are categorical. We analyze an association through a comparison of conditional probabilities and graphically represent the data using contingency tables (Two-way table).
We have to make the two - way table of the X and Y values.
What is categorical variables ?
- A categorical variable (also known as a qualitative variable) in statistics is a variable that may take one of a restricted, and typically fixed, number of potential values, allocating each human or other unit of observation to a specific group or nominal category based on some qualitative feature.
- Some variables can be said to be categorical, or they can be treated as such based on the length of their unique values.
- For example, if a variable contains only unique values [-2,4,56], you may consider it categorical.
- Every unique value in every category variable will result in the creation of a new column.

Answer:
X = 9.5 + m
Step-by-step explanation:
m = money spent
x = money you had at the beginning
x = 9.5 + m
Substitute m in for 3.4
X = 9.5 + 3.4
Solve for x
X = 12.9
You started with $12.90
Step-by-step explanation + Answer:
x = 1st job
y = 2nd job
x + y = 22......x = 22 - y
7x + 8.25y = 171.50
7(22 - y ) + 8.25y = 171.50
154 - 7y + 8.25y = 171.50
-7y + 8.25y = 171.50 - 154
1.25y = 17.50
y = 17.50 / 1.25
y = 14 <== 14 hrs at the 8.25 per hr job
x + y = 22
x + 14 = 22
x = 22 - 14
x = 8 <=== 8 hrs at the 7 per hr job
