Answer:
Step-by-step explanation:
First write 0.16 is a fraction. Start by dividing 16 by 100.
Now adding the 17 to that fraction that is equivalent to 0.16:
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:
x- intercept is at .
y- intercept is at .
Step-by-step explanation:
The x-intercept occurs when y=0.
Thus, substitute y= 0 into the equation to find the x- intercept.
-3x +6y= 11
When y= 0,
-3x +6(0)= 11
-3x= 11
x= 11 ÷ (-3)
The y-intercept occurs at x= 0.
When x= 0,
-3(0) +6y= 11
6y= 11
y= 11÷ 6
