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.
Answer:
y = -3x/4+3/2
Step-by-step explanation:
The amount of sales (S) of statin in billions of dollars by 2017 is 34.5 billions
<h3>Linear equations</h3>
Linear equation are equation that has a leading degree of 1. Given the equation that represents Statins used to keep cholesterol in check and are a top-selling drug in the U.S.
S-1.5x = 6
where
S is the amount of sales
x is the number of years after 1998
By 2017, the total number of years is 19 years
Substitute
S = 1.5x + 6
S = 1.5(19) + 6
S = 28.5 + 6
S = 34.5
The amount of sales (S) of statin in billions of dollars by 2017 is 34.5 billions
