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:
I'll set up the problem and you can do the calculation
Step-by-step explanation:
we need to complete the squares to get the equation in the general form:
where h = the x coordinate of the center
k = the y coordinate of the center
r = the radius
so looking at
we can see that if use -1 as the constant we have
doing the same for y
we can use -2 as the constant (basically you that the s
quare of the y coefficient )
so now we have to add or subtract the constant on the RHS to see what the square of the radius is according to the general form of the equation at the top
20 +1+4=25
Take the square root and you have the radius
