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
Answer:
Option 4 is the correct option.
Step-by-step explanation:
We need to solve the expression 2x(x+2)(x-3)
Multiplying the terms with each other we get,
Option 4 is the correct option.
Answer:
Step-by-step explanation:
nth term = 3n+2
a) first term = 3+2 = 5
Second term = 3(2)+2 = 8
Third term = 3(3) +2 = 11
b) tenth term = 3(10)+2 = 32
I think the answer is half of one number to the other
