This is an answer I wrote last year check it out I have it in my progress
Thanks for writing out the whole question, m=x is the correct answer. So B. Since the denominators are equal, the numerators must be too
The number of scores that are less than 72 is 12.
Solution:
In the given histogram represents the scores of golfers.
x-axis represents the scores and y-axis represents the number of scores.
Number of scores between 66 - 67 = 4
Number of scores between 68 - 69 = 2
Number of scores between 70 - 71 = 6
Number of scores between 72 - 73 = 2
Number of scores between 74 - 75 = 2
To determine the number of scores that are less than 72.
Number of scores less than 72 = 4 + 2 + 6
= 12
Hence the number of scores that are less than 72 is 12.
