Answer:
3.88
Step-by-step explanation:
|Ω| = 6 - number of all results
A = {1, 3} → |A| = 2 - number of (a) results
P(A) = 2/6 = 1/3
You know that the radical is in the simplest expression form if there are not squares or cubed roots in the radical. If there is then it can be simplified more. When the radical can no longer be simplified then it is in the simplest form
Answer:
See below in bold.
Step-by-step explanation:
f(x)=(x-15)(x+1)(x-10) = 0
The zeroes of the function are found as follows:
x - 15 = 0, so x = 15.
x + 1 = 0 and x - 10 = 0.
- in the same way -1 and 10 are also zeroes.
