Hello from MrBillDoesMath!
Answer: x = -1, 12
Discussion:
I will assume the problem means to solve for x in
11/(3x) - 1/3 = -4/ (x^2)
Multiply both sides by 3
11/x - 1 = (-4 *3)/ x^2
Multiple both sides by x^2
(11/x) * x^2 - x^2 = ((-12)/ x^2) * x^2 or
11x - x^2 = -12. Rearrange to get
x^2 - 11x - 12 = 0. Factor this equation:
(x-12) (x +1) = 0
so the roots are x = -1, 12
Thank you,
MrB
Answer:
No. See explanation below.
Step-by-step explanation:
A random sample is a type of sample in which every item has the same probability of being selected. Equally, after we take one item, the remaining items keep having the same probability of being selected.
In this problem, the vitamin pills are firstly obtained from the pills produced in an hour at the Health Supply Company, therefore, not all pills had the same probability of being selected in the first place.
