First, you have to find the median, which is the number in the middle: 25
Then cut the data in half by the median, so your new data sets are
15,29,20
and
31,38,41
Now you find the median of both of those sets, which is 29 and 38.
The interquartile range is the difference between the numbers, so 38-29 = 9.
X=12
This is because you subtract 6 from both sides to get the x isolated.
So x=18-6
x=12 :)
Answer:
0.525
Step-by-step explanation:
\frac{x}{3.50}=\frac{15}{100}
Assuming the numbers are percents, the answer is 25%, because 5/20 is 1/4, then convert the fraction to a percentage and you get 25%.
Y=-2 should be the answer
