c) There is a 10.32% probability that exactly five owners would say having good financing ready is the most important advice.
d) The expected number of owners who would say having a good plan is the most important advice is 2.28
Step-by-step explanation:
Questions a), b), c) are all solved as binomial distribution problems.
Question d) is a simple calculation.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which C_{n,x} is the number of different combinatios of x objects from a set of n elements, given by the following formula.
And is the probability of X happening.
For these problems
12 business owners were contacted, so .
a. What is the probability that none of the owners would say preparing for long hours and hard work is the most important advice?
20% of all small-business owners say the most important advice for starting a business is to prepare for long hours and hard work, so .
That is P(X=0) when .
There is a 6.88% probability that none of the owners would say preparing for long hours and hard work is the most important advice.
b. What is the probability that six or more owners would say preparing for long hours and hard work is the most important advice?
20% of all small-business owners say the most important advice for starting a business is to prepare for long hours and hard work, so .
This is:
So:
There is a 1.93% probability that six or more owners would say preparing for long hours and hard work is the most important advice.
c. What is the probability that exactly five owners would say having good financing ready is the most important advice?
Twenty-five percent say the most important advice is to have good financing ready, so
There is a 10.32% probability that exactly five owners would say having good financing ready is the most important advice.
d. What is the expected number of owners who would say having a good plan is the most important advice?
Nineteen percent say having a good plan is the most important advice, so that is
The expected number of owners who would say having a good plan is the most important advice is 2.28
Answer:
The equation to determine the total length in kilometers is
The total length in kilometers of Josh’s hike is 38 km.
Step-by-step explanation:
Given:
Let the total length in kilometers of Josh’s hike be h.
Now Given that He has now hiked a total of 17 km and is 2 km short of being 1/2 of the way done with his hike.
It means that to reach half of the length of total length Josh needs 2 more km to add in his hiking which is done which is of 17 km.
Framing the above sentence in equation form we get;
Hence, The equation to determine the total length in kilometers is
Now Solving the above equation we get;
First we will multiply 2 on both side using Multiplication property we get;
Hence, The total length in kilometers of Josh’s hike is 38 km.
