Median and IQR are the appropriate measure for the center and spread of the given data set. (Option B and C)
<u>Step-by-step explanation:</u>
Usually the center and spread can be measured by various means, Among them Median and Inter Quartile Range are the best known appropriate methods.
Median:
Median is the better measure of a center, since it is the middle value and it is not affected by any outliers and it is also better than the mean value to measure the center.
Inter Quartile Range (IQR):
Inter Quartile Range (IQR) is better to measure the spread, since the outliers mislead and the utmost items will show maximum standard deviation.
So to measure Spread and center, we can use the following,
- spread - IQR
- center - median
Since the maximum exponent of x is 3, there should be three roots.
Unless you have a root squared and multiplyed by a different root, you will only have two roots since two are the same.
Also, if all three roots are the same, you only have one root.
We can form a system of equations:
x*y=90
and
x=2y+3.
Solving gives dimensions of 15 feet by 6 feet.
