20 is the answer
I hope this help
Answer:
1 and 19
Step-by-step explanation:
I believe this is a factoring problem.
Example:
If we have the equation x^2-2x-3
We can find two numbers that multiply to -3 that add to -2
The two numbers are -3 and 1
(x-3)(x+1)= So x=3 and x=1
Answer:
Y-intercept=-4
Step-by-step explanation:
When you are finding the y intercept of something, you cover up the other variable because you would insert zero. In this case, x would be 0 and it will leave you with the equation, -2y=8 Just solve the rest using algebra--
-2y=8
-y=4
y=-4
So that means that the y intercept would be -4

First find the probability of each color being drawn.
We need to find the total number of marbles first.
4 + 3 + 6 = 13
So everything will be over 13.
Probability of a white marble being drawn --> 
Probability of a blue marble being drawn --> 
Probability of a red marble being drawn --> 
Now to find the probabilities of more than one being drawn, we can multiply.
Part a :
Part b :
Part c :
Part d :
