Answer:
Probability of not drawing a green marble is 19/23.
Step-by-step explanation:
A jar is containing 7 red, 3 white, and 9 blue marbles.
Then the probability to draw a green marble will be = Numbers of green marbles/ Total numbers of marbles of all colors
P(G) = 4/(7 + 4 + 3 + 9)
P(G) = 4/23
Now the probability of not drawing a green marble = 1 - probability of drawing a green ball
P = 1 - 4/23 = 19/23
Therefore answer is 19/23.
Answer:
There are 3 roots of the given equation.
Step-by-step explanation:
Given the equation
we have to tell the number of roots of the given equation.
As the number of roots for an equation is equal to degree.
The degree of a polynomial is the highest power of its monomials with non-zero coefficients.
Hence, number of roots is the highest power in the equation.
Now, the equation is
The highest power i.e degree of equation is 3.
hence, there are 3 roots of the given equation.
Hi
7(-3)(-2)²
-21(-2)²
-21(4)
= -84
I hope that's help !
