The interquartile range (IQR) is 15.
To find the IQR, you must:
1) Find the median
2) Split the data set in two at the median.
3) Find the medians from both the groups you made in Step 2
4) Label the smaller one Quartile 1 and the larger one Quartile 3 (Hint: The median is Quartile 2)
5) Subtract: Quartile 3 - Quartile 1
Answer:
0.125 is the answer
Step-by-step explanation:
Log6(5-2a/3a)=1
6^1=(5-2a/3a)
6(3a)=5-2a
18a=5-2a
20a=5
a=1/4
Answer:

Step-by-step explanation:
Slope can be represented as rise over run (change y-values over change in x-values). Since the y-value is changing by -2 every time the x-value is changing by 2, the slope of the line must be
.
In slope-intercept form
,
represents the slope of the line,
represents the y-intercept, and
represent the coordinates of any point the line passes through.
To find
, substitute
and any point the line passes through.
Using (1, 0) from the table:

Thus, the equation of this line is
