Patrice and her husband are going on a 6-mile hike. So far they have hiked 3 miles. How much farther do Patrice and her husband have left to hike?
3

3 miles

Step-by-step explanation:

6 total miles

3 miles done

6 (total) = 3 (done) + x (unknown)

x = 6 - 3

x = 3

3 miles left to hike

if x decreases by 4 then y increases by 10

step-by-step explanation:

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
