Answer:
The probability that a randomly chosen Ford truck runs out of gas before it has gone 325 miles is 0.0062.
Step-by-step explanation:
Let <em>X</em> = the number of miles Ford trucks can go on one tank of gas.
The random variable <em>X</em> is normally distributed with mean, <em>μ</em> = 350 miles and standard deviation, <em>σ</em> = 10 miles.
If the Ford truck runs out of gas before it has gone 325 miles it implies that the truck has traveled less than 325 miles.
Compute the value of P (X < 325) as follows:

Thus, the probability that a randomly chosen Ford truck runs out of gas before it has gone 325 miles is 0.0062.
Answer:
It is VERY important to use the attached formula.
Years = ln (Total / Principal) / rate
Years = ln (6,000 / 2,000) / rate
Years = ln (3) / rate
Years = 1.0986122887 / .015
Years = 73.24 years
This takes a LONG time because the interest rate is extremely low.
