Answer:
3003.
Step-by-step explanation:
This is the number of combinations of 5 books from 15 = 15C5
= 15! / 10! 5!
= 15*14*13*12*11 / 5*4*3*2*1
= 3*7*13*11
= 3003.
Answer:
The coefficient of variation for <em>A</em> is 24.6%.
The coefficient of variation for <em>B</em> is 33.7%.
Step-by-step explanation:
The coefficient of variation (<em>CV</em>) is well defined as the ratio of the standard deviation to the mean. It exhibits the degree of variation in association to the mean of the population.
The formula to compute the coefficient of variation is,
Consider the data set <em>A.</em>
Compute the mean of the data set <em>A </em>as follows:
Compute the standard deviation of the data set <em>A </em>as follows:
Compute the coefficient of variation for <em>A</em> as follows:
The coefficient of variation for <em>A</em> is 24.6%.
Consider the data set <em>B.</em>
Compute the mean of the data set <em>B </em>as follows:
Compute the standard deviation of the data set <em>B </em>as follows:
Compute the coefficient of variation for <em>B</em> as follows:
The coefficient of variation for <em>B</em> is 33.7%.
Answer:
There are approximately 1145 vehicles are stuck in the traffic jam. It is very close to option C.
Step-by-step explanation:
To determine:
Estimate how many vehicles are stuck in the traffic jam.
Information Fetching and Solution Steps:
- On a residential single lane road there was a wreck that backed up traffic for 4 miles.
- 70% of the traffic consists of cars and 30% of the traffic consists of trucks.
- The average distance between vehicles is 3 feet.
- The average length of a car is 13.5 feet.
- The average length of a truck is 20 feet.
- There are 5280 feet in 1 mile
Let 'n' be the total number of vehicles stuck in the traffic jam.
So, the equation becomes
Estimating to get the integer vehicle number and rounding it to the nearest integer.
vehicles
Therefore, there are approximately 1145 vehicles are stuck in the traffic jam, which is very close to option C.
