Here are the city gas mileages for 13
1 answer:
The third quartile is 23
Step-by-step explanation:
To find the third quartile of set of data do that:
- Arrange the data from smallest to largest
- Find the median of the data (middle number)
- The 3rd quartile (Q3) is the median of the upper data, (the upper data is the data after the median of the data)
∵ The city gas mileages for 13 different midsized cars in 2008
are 16, 15, 22, 21, 24, 19, 20, 20, 21, 27, 18, 21, 48
- Arrange the data from smallest to largest
∴ 15, 16, 18, 19, 20, 20, 21, 21, 21, 22, 24, 27, 48
∵ The set has 13 numbers
∴ The middle numbers is the 7th
∵ The 7th number is 21
∴ The median of the set is 21
∵ The upper data is the data after the median
∴ The numbers of the upper data are 21, 21, 22, 24, 27, 48
∵ The upper data has 6 numbers
- The median is the average of the middle two numbers
∴ The middle numbers are 22 and 24
∵ Their average = = 23
∴ The median of the upper data is 23
- The median of the upper data is the third quartile
∴ Q3 = 23
The third quartile is 23

Answer:
She can visit the cities in 192 ways
Step-by-step explanation:
If Sally starts from city A and after going to 4 cities she returns to home,
then that can be in 4! = 24 ways. (permutation of 4 distinct objects)
If between the time she visits cities, she comes home once,
then cities can be visited in,
= 72 ways. (permutation of 4 distinct objects and choosing 1 gap among the 3 )
If between the time she visits cities, she comes home twice,
then cities can be visited in,
=72 ways. (permutation of 4 distinct objects and finding 2 gaps among the 3)
If between the time she visits cities, she comes home thrice,
then cities can be visited in,
= 24 ways. (permutation of 4 distinct objects and choosing 3 gaps among the 3)
Now, she can't come home more than thrice in between the time she visits cities (since there are 4 cities to visit only)
So, the number of ways she can visit cities = (24+ 72 + 72 + 24)
= 192
Answer :
M = 135
Step by Step Explanation :
See the photo attached :) it’s kinda hard to explain in words but you cancel out the 36.50 by subtracting it on both sides, and then the equation becomes 13.50 = 0.10m. Since we have to get the m by itself, you cancel out the 0.10 by subtracting on both sides, and it leaves you with 135 = m
