A lolly bag contains 2 red, 3 green and 2 blue gum balls. What is the probability of selecting a green one?
A) 5/7
B)4/7
C)3/7
D)2/7

C

Step-by-step explanation:

Okay, first you would add up all the gumballs.

2+3+2=7

Now that will be the denominator.

Now for the numerator. You will check the question and find how man green gumballs there are. There are 3. So, now make it a fraction.

The answer choice is C.

Hope this helped!

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

i believe that the slope of the line is -5
