Answer:
C) independent variable = age
dependent variable = reaction time in milliseconds
Step-by-step explanation:
The linear regression statistical test is best used for research experiment where there is a single dependent and one independent variable whjre both variables are numeric. In the given options above, the city of residence, gender, college major and political affiliation are all possible categorical variables and age, salary, miles driven and reaction time are all numerical variables. Hence, the best situation in which to use linear regression is a test where both the independent and dependent variables are either age, salary, reaction time or miles driven.
You need 20 oz. of punch with 3 parts ginger ale and 2 parts HI-C. So the end result will have 5 parts. To find out how many ounces are in each part, just divide the total (20) by the number of parts (5):
20 / 5 = 4
There will be 4 ounces per part.
First, solve for the amount of ginger ale. The problem says the punch is 3 parts ginger ale, so just multiply the number of parts by the amount in each part:
(3)(4) = 12
The punch will have 12 ounces of ginger ale.
Next, solve for the amount of HI-C. The problem says the punch is 2 parts HI-C, so just multiply the number of parts by the amount in each part:
(2)(4) = 8
The punch will have 8 ounces of HI-C.
Hope this helps!
