The answer would be A. 1/4 bc you add all the marbles together then divide by the amount of the color you’re looking for
Answer:
Option B. It represents a nonlinear function because its points are not on a straight line.
Step-by-step explanation:
Let
we know that
If point A,B and C are on a straight line
then
The slope of AB must be equal to the slope of AC
The formula to calculate the slope between two points is equal to
<em>Find the slope AB</em>
substitute in the formula
<em>Find the slope AC</em>
substitute in the formula
so
Points A, B and C are not on a straight line
therefore
It represents a nonlinear function because its points are not on a straight line
Answer:
x = 3 and -2 are the two solutions.
Step-by-step explanation:
2x^2 -2x -12 = 0
First factor out a 2
2(x^2 - x - 6) = 0
2(x - 3)(x + 2) = 0
2 = 0 x - 3 = 0 x + 2 = 0
2 does not equal zero so this is an extraneous solution
x - 3 = 0 so x = 3
x + 2 = 0 so x = -2
We know that
38% of the incoming students own both a smartphone and a tablet
84% of the students own a smartphone
We are asked to find the percentage of students who own a smartphone
Let N be the total number of incoming students and S be the total number of students
So,
(N (38%) + S (84%)) / (N + S)
If we know the total number of students or incoming students, we can solve for the percentage by substituting the value of N or S
