Answer:

43 9/10 miles

Step-by-step explanation:

2(1 3/4) + 2(20 1/5) = 2(7/4) + 2(101/5) = 14/4 + 202/5 = 7/2 + 202/5

common denominator will be 10

7(5) = 35

202(2) = 404

35/10 + 404/10 = 439/10 = 43 9/10 miles

Which one of these data sets has a mean that is different from the others?
Kamila [148]

Answer:

The top right graph.

Step-by-step explanation:

If you find the mean for all the graphs you get:

Graph 1: 7                                         Graph 2: 2

Graph 2: 7                                        Graph 4: 7

To find the mean you all all the numbers up and divide it by the number of data points for example heres the first graph:

8 + 8 +8 +8 +8 +8 +1 = 49    Add the data points

49 / 7 = 7                              Divide by the total amount of points which is seven
