Answer:
It increased by 25%
Step-by-step explanation:
I only know of two measures of central tendency. Those are the median and the mean.
The mean is the average value of all numbers in the data set. It is adding up all the number and dividing it by the count of the data set.
The median is found as the middle most value of the data set that is arranged in ascending value.
In this scenario, it is better to use the MEDIAN in Cindy's report to the principal to portray her students in the most favorable manner. The median may either be a C or B. The F grade will not be considered.
Hi there!
To solve this problem, let's set up a proportion: 1/30 = x/45. Now, cross-multiply to get an equation: 30x = 45. Now, divide each side by 30 to figure out how many centimeters would be used to represent 45 kilometers: x = 2/3 or 0.666 cm.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
