<h2>1. y-intercept</h2>
The quadratic function represents a parabola. In fact, the graph of a quadratic function is a special type of U-shaped curve called a parabola. To find the y intercept, we set
as follows:
To find the other x-intercept, we must set as follows:
Therefore, the other x-intercept is . You can see both the y-intercept and the x-intercepts in the figure below.
Answer:
Probability that a student chosen randomly from the class plays basketball or baseball is or 0.76
Step-by-step explanation:
Given:
Total number of students in the class = 30
Number of students who plays basket ball = 19
Number of students who plays base ball = 12
Number of students who plays base both the games = 8
To find:
Probability that a student chosen randomly from the class plays basketball or baseball=?
Solution:
---------------(1)
where
P(A) = Probability of choosing a student playing basket ball
P(B) = Probability of choosing a student playing base ball
P(A \cap B) = Probability of choosing a student playing both the games
<u>Finding P(A)</u>
P(A) =
P(A) = --------------------------(2)
<u>Finding P(B)</u>
P(B) =
P(B) = ---------------------------(3)
<u>Finding </u>
P(A) =
P(A) = -----------------------------(4)
Now substituting (2), (3) , (4) in (1), we get
