PLEASE HURRY I WILL MARK AS BRAINLIST 6) Mark made a trip to his friend's house and
back. On the trip there he traveled 28
km/h and on the return trip he went 70
km/h. How long did the trip there take if
the return trip took two hours?
A) 7 hours B) 3 hours
C) 8 hours D) 5 hours

D

Step-by-step explanation:

70 divided by 28 = 2.5

2.5 x 2 hours = 5 hours.

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.
