There is an association because the value 0.15 is not similar to the value 0.55
For the nutritionist to determine whether there is an association between where food is prepared and the number of calories the food contains, there must be an association between two categorical variables.
The conditions that satisfy whether there exists an association between conditional relative frequencies are:
1. When there is a bigger difference in the conditional relative frequencies, the stronger the association between the variables.
2. When the conditional relative frequencies are nearly equal for all categories, there may be no association between the variables.
For the given conditional relative frequency, we can see that there exists a significant difference between the columns of the table in the picture because 0.15 is significantly different from 0.55 and 0.85 is significantly different from 0.45
We can conclude that there is an association because the value 0.15 is not similar to the value 0.55
Answer:
5,-5
Step-by-step explanation:
|x|=a
x=±a
|x|=5
x=±5
To find the sales tax multiply the purchase price by the sales tax rate. Remember to convert the sales tax rate from a percent to a decimal number. Once the sales tax is calculated, it is added to the purchase price. The result is the total cost—this is what the customer pays.
Associative property is the answer.
See below for the description of changes when the dependent and the independent variables are switched
<h3>How to determine the changes?</h3>
<u>The table of values</u>
When the dependent and the independent variables are switched, the values also become switched on the table.
This means that the table becomes an inverse table of the function
<u>The scatter plot</u>
Switching the variables implies that the original function is being reflected across the line y = x
<u>The description in words</u>
This description is an inverse relation of the original function
<u>The equation</u>
This description is an inverse equation of the original function.
If the initial equation is y = ax + c, the new equation becomes x = ay + c
