Answer:
Experimental P (red) = 24 Theoretical P (Red) = 30
Experimental P (Blue) = 14 Theoretical P (Blue) = 10
Experimental P (Yellow) = 22 Theoretical P (Yellow) = 20
Part (a)
Plug in y = 0 and solve for x. Use the zero product property
y = x(x+3)(x-2)
0 = x(x+3)(x-2)
x(x+3)(x-2) = 0
x = 0 or x+3 = 0 or x-2 = 0 .... zero product property
x = 0 or x = -3 or x = 2
The three roots or zeros are x = 0 or x = -3 or x = 2
================================================
Part (b)
The roots of the graph are: x = -2, x = 1, x = 3. Each root is where the graph crosses or touches the horizontal x axis.
Note how x = 0 is found in part (a), but not found here. This is one example where the graphs don't match. Another would be x = -3 is in part (a), but not here.
So that's why the graph does <u>not</u> match with the function in part (a)
Answer: 1- quadrant 1 or top right
2- quadrant 4 or bottom right
3-quadrant 3 or bottom left
<span>49 + 28 = 7(7 + 4)
In a distributive property you need to multiply a term by two or more terms in a </span><span>parentheses. So we cancel B and C.
Then you have to choose which one out of A or B will and up with the same answer as 49+ 28. </span>
