Sample space={5 B + 6 R + 9 G} = 20 (all possible outcomes
Favorable outcome ={6 R} = 6
P(1st Drawing R) = 6/20 = 3/10
Once drawn and not replaced the total remaining marble = 19 and within the 19, there are 5 Red left. So
P(2nd Drawing R) = 5/19
P( 1st AND 2nd R) = (3/10)x(5/19) = 3/38 = 0.0789
Answer:
a = 8
b = -8
Step-by-step explanation:
You have the following function:

A function is differentiable at a point c, if the derivative of the function in such a point exists. That is, f'(c) exists.
In this case, you need that the function is differentiable for t=2, then, you have:

If the derivative exists for t=2, it is necessary that the previous derivatives are equal:

Furthermore it is necessary that for t=2, both parts of the function are equal:

Then, a = 8, b = -8
Answer:
B and C
Step-by-step explanation:
Linear functions are written in the format y=mx+b
If a function has an exponent it is nonlinear
Answer:
x = 5, -1
Step-by-step explanation:
0 = 3x^2 - 12x - 15 or
3x^2 - 12x - 15 = 0
By solving for x, use the Quadratic Formula.
… x = 5 and/or -1
