Answer:
4(m+3)=18
m+3=18/4=9/2
m=9/2-3
m=9-6/3
m=3/3=1
so,
m=1
Step-by-step explanation:
Solution: For a positively skewed distribution with a mean of m=20, the most probable value for the median is less than 20.
<u>Explanation:</u>
We know that in a symmetric distribution, the relationship between mean, median and mode is:

In case of negatively skewed distribution, the relationship between mean,median and mode is:

In case of positively skewed distribution, the relationship between mean,median and mode is:

Therefore, for a positively skewed distribution with a mean of m = 20, the median would be less than Mean. Hence the probable value of median is less than 20

-311.74
Step-by-step explanation:
Each piece is 20 inches long.
Step-by-step explanation:
The length pieces of the ribbon can be obtained by dividing the total length of ribbon by total number of pieces
Given
String length = 168 inches
Number of pieces = 6
So the length of each piece will be:

Cutting 8 inches from each piece means that the length will be reduced 8 inches

Hence,
Each piece is 20 inches long.
