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:
There are 16 no-bake cookies.
Step-by-step explanation:
1 : 1 : 3
x : x : 48
x = 48 / 3
x = 16
Answer:
Step-by-step explanation:
3/4x = 6 Multiply both sides by 4/3
4/3 * 3/4 x = 6*4/3 Combine
x = 6 * 4/3
x = 6 * 4/3
x = 24/3
x = 8
Answer:
Whatever option has a slope of 3/4 and isn't y = 3/4x + 2
Step-by-step explanation:
This means that it has to have a slope of 3/4 (written as 3/4x + b). This is because parallel lines have the same slope; rearranging the first equation gets us y = 3/4x + 2. So, our slope for a parallel line has to be 3/4.

Multiple each term in the brackets by 4a
4a (8a - 4a + 1)
4a (4a + 1)
