The answer of the question is A
<h3>
Answer: 7/12</h3>
=================================================
Explanation:
There are B = 3+5+4 = 12 marbles total, of which A = 12-5 = 7 are not black. Or you could note that we have A = 3 red + 4 white = 7 marbles that are not black.
The probability of selecting a non-black marble is A/B = 7/12
7/12 = 0.5833 = 58.33% approximately
Subsitutue in so basically just multiply all the numbers together instead of using that formula use P.R.T. percent, rate, and time to get interest

Answer:
y+2=3(x-1/9)
Step-by-step explanation:
y-y1=m(x-x1)
y-(-2)=3(x-1/9)
y+2=3(x-1/9)
