According to the probability distribution, there is a 0% probability that a randomly selected student earns more than 18 credits.
- A student earns 3 credits <u>per course</u>.
Thus, the probability distribution for the <u>number of credits earned</u> is:






Since no person takes more than 6 courses, there is a 0% probability that a randomly selected student earns more than 18 credits.

Answer:
0.4
Step-by-step explanation:
1.6 - 1.2 = 0.4
When the decrease in velocity (the acceleration) is uniform, the average velocity is [Initial velocity - Final velocity]/2
We know tha the initial velocity is 0.96 rev / sec and the final velocity is 0,
Then, the average velocity is [0.96 / 2 ]rev /sec = 0.48 rev/sec.
Also, by defintion,
average velocity = number of rev / time,
From which, number of rev = average velocity * time
So, number of rev = 0.48 rev/sec * 2.4 min * 60sec /min = 69.12 rev
Answer: 69.12 revolutions
I think its 2 because if you divide 20,000 over 1000 you get 2. If you do that for the other values, you would also get 2.
