Step-by-step explanation:
It is a pattern where you add 3 each time
Answer:
75
Step-by-step explanation: Well, since you didn't say what fiction was, I have no way to confirm this, but if 36, 20, and 30 add up to 86, and I use 36 (comedy) and multiply it by the amount of students serveyed, I get 5,400. Devide that by 86 (the total of all servey) You get 62, and again, since I don't have the percent for fiction, I will have to say that it is most likely 75, due to that being the only number above 62.
You shouldn't need a calculator for this. The quadratic equation is written in standard form.
ax^2 + bx + c = 0
You substitute a, b, and c into the discriminant formula and solve as shown in the example in the picture you provided.
(-7)^2 - 4(2)(-8)
49 - 4(-16)
49 - (-64)
49 + 64
113
Best of Luck!
