The function F(x) = 6x-2/x+5 is an example of a rational function. True or False?
1 answer:
Answer:
True
Step-by-step explanation:
we know that
A <u>rational function</u> is the ratio of two polynomials, in which the denominator has a degree of at least 1 . In other words, there must be a variable in the denominator.
In this problem we have
The numerator is a linear polynomial (degree 1)
The denominator is a linear polynomial (degree 1)
therefore
The function f(x) is a rational function
The statement is true

Answer:
a)
b)
Step-by-step explanation:
Number of balls in the urn = 12
Number of white balls in the urn = 4
So, number of balls which are not white = 12 - 4 = 8
We know that probability = No. of outcomes/Total number of outcomes
Let denotes the event of getting white ball by A, B and C
a) each ball is replaced after being drawn.
Probability = Number of white balls/Total number of balls
Solution:
b)the balls that are withdrawn are not replaced.
Solution:
If A wins:
If A lost and B wins:
If A and B lost and C wins:
and so on....
