Answer:

Step-by-step explanation:

The interval notation is (-12, 12).

The probability of choosing Joey first is 1/12 .
If that happens, the probability of choosing Chloe next is 1/11 .
Then, the probability of choosing Zoe after that is 1/10 .
The probability of all these things happening is
(1/12) x (1/11) x (1/10)
= 1/1320 = 0.00076 = 0.076 percent
Answer:
(C)
Step-by-step explanation:
Given the distance, d(t) of a particle moving in a straight line at any time t is:

To find an expression for the instantaneous velocity v(t) of the particle at any given point in time, we take the derivative of d(t).

The correct option is C.
