683/100 would be the correct answer In mixed fraction
Answer:
68%
Step-by-step explanation:
We observe that the mean of the sample is (61+71)/2 = 66 mph which means the standard deviation of the sample is 5 because 66-5=61 and 66+5=71. The Empirical Rule states that for data observed in a normal distribution, 68% of data will fall within one standard deviation of the mean. Therefore, approximately 68% of vehicles travel between 61 miles per hour and 71 miles per hour.
Answer:
5 and 5/12 hours because you just add them up.
Step-by-step explanation:
they all have a common denominator so you don't need to worry about finding one. 1 + 2 + 1. Then you do 11/12 + 1/12 + 5/12 and add up the two bolded things that I did. Your Welcome!!
