Answer:
369 students have taken a course in either calculus or discrete mathematics
Step-by-step explanation:
I am going to build the Venn's diagram of these values.
I am going to say that:
A is the number of students who have taken a course in calculus.
B is the number of students who have taken a course in discrete mathematics.
We have that:
In which a is the number of students who have taken a course in calculus but not in discrete mathematics and is the number of students who have taken a course in both calculus and discrete mathematics.
By the same logic, we have that:
188 who have taken courses in both calculus and discrete mathematics.
This means that
212 who have taken a course in discrete mathematics
This means that
345 students at a college who have taken a course in calculus
This means that
How many students have taken a course in either calculus or discrete mathematics
369 students have taken a course in either calculus or discrete mathematics
Answer:
Option D is correct
The initial value is 2
Step-by-step explanation:
The equation of line passes through the origin is represented by:
y = mx where m is the slope or unit rate .
Direct Proportionality says that:
if then the equation of the form is y = kx where k is the constant of proportionality.
Given the equation:
Then by definition:
m = 2
⇒ Slope on the line is 2.
⇒ the unit rate is 2.
Also, the constant of proportionality is 2.
Therefore, the statement which is not true for the equation y=2x represents a set of data is: The initial value is 2
