The table below shows a set of data. data x y 6 71 7 68 7.5 69 7.5 65 8 63 8.25 62 8.25 64 9 60 9.5 61 which of the following points, if added to the table, would be an outlier? (7, 73) (7.5, 70) (8, 35) (8.5, 66)

The outlier would be:

                        (8,35)

We are given a data set as:

      x         y

      6        71

      7        68

     7.5      69

     7.5      65

        8      63

     8.25    62

     8.25    64

         9      60

       9.5     61

Clearly when we add the points given in options to our data we see that the points (7, 73) (7.5, 70) (8.5, 66) are closely related to the data set except (8,35).

Since, the value y=35 is much low as compared to the other data points.

Hence, it will stand out in the plot as compared to other points.

       Hence, the point which is an outlier is:

                     (8,35)

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
