Answer:
Gender is a categorical variable. The sum gives the total number of students in class.
Step-by-step explanation:
We are given the following in the question:
The variable Male, is categorical, even though its values are numbers.
Categorical variable:
- These variable are the non parametric variable.
- They do not need values to express the data.
- They only use number and numerical to express the data or represent the data.
- There is no relation with true value of numerical.
Thus, gender is a categorical variable. Numbers are only used to represent the data.
Numbers are just a representation.
The sum of these represent the total male and female students in class. Thus, the sum gives the total number of students in class.
Redville = r
Greenboro = 12r
Total of the two towns = 65
Now we can set up our equation.
r + 12r = 65
13r = 65
13r/13 = 65/13
r = 5
Redville gets 5 inches
Gas mileage is the number of miles you can drive on a gallon of gasoline.A test of a new car results in 330 miles on 10 gallons of gas.how far could youdrive on 65 gallons of gas?what is the car's mileage?
u would multiply 330 and 6
then divide 330 in half
330x6=1980
330/2=165
then add those together
and u would get 2145
