This problem describes two points in a route of 4 hours. He went through 68 miles after the first two hours, and 132 miles after 4 hours of driving. We need to calculate the average rate of change.
The average rate of change is the division between the total distance and the time it took to travel that distance, so we have:

The average rate of change is equal to 33 miles per hour.
Answer:
The required probability is 0.0155.
Step-by-step explanation:
We are given that the one-year survival rate for pancreatic cancer is 20%.
Of 12 people diagnosed with pancreatic cancer at one hospital, 6 survived one year.
The above situation can be represented through binomial distribution;

where, n = number of trials (samples) taken = 12 people
r = number of success = 6 survived
p = probability of success which in our question is probability of
one-year survival rate for pancreatic cancer, i.e; p = 20%
Let X = <u><em>Number of people survived one year</em></u>
So, X ~ Binom(n = 12 , p = 0.20)
Now, the probability that 6 survived one year is given by = P(X = 6)
P(X = 6) =
=
= <u>0.0155</u>
Answer:
584.03
Step-by-step explanation:
Given that principal amount = 500.20 dollars
Interest rate = 3 7/8% p.a.= 3100/8(12) per month
Period = 4 years = 4(12) = 48 months.
A= P(1+r/n)^nt
Here n = 12 t = 4 years.
Substitute to get
Future value = 
=584.03
1: x divided 7. 2: 10 + x. 3: x - 14. 4: 8x
