Answer:
<u>The numbers are 12 and 32.</u>
Step-by-step explanation:
x = One number
x - 20 = Another number
3x - (x - 20) = 84 (If the lesser number is subtracted from three times the greater number, the difference is 84)
Let's solve for x, this way:
3x - (x - 20) = 84
3x - x + 20 = 84
2x = 84 - 20 (Subtracting 20 at both sides)
2x = 64
x = 64/2
<u>x = 32 ⇒ x - 20 = 12</u>

Answer:
C. Uniform distribution
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that X is between values c and d, in which d is greather than y is given by:
In this problem, we have that:
Suppose the probability of a car accident taking place anywhere on a 20-mile stretch of highway is the same, which means that
Somewhere between the 5-mile and 15-mile posts of the highway:
So the correct answer is:
