Well to solve these type of question it is very easy to make a tree diagram and then solve them. How ever i have done it here for you.
So basically we have to get a pen from the first box so its probability is 7 / 10.
Similarly, we have to get a crayon from the second box so its probability is 2 / 8.
Now by counting principle we can multiply the two probabilities so 7/10 * 1/4 which becomes equal to 7/40.
Answer:
Situation 2 (B)
Step-by-step explanation:
I think it would be B since the power of the gear increases proportionally with the radius.
F(x)=x-4

Answer:
Option C
Step-by-step explanation:
I interpret as (5x-6)(3x^2-4x-3)
Expanded: 15x^3-20x^2-15x-18x^2+24x+18
15x^3-38x^2-15x+24x+18
15x^3-38x^2+9x+18
So the correct choice will be C
It simplifies down to x + 4
Hope I helped C:
