Answer:
Step-by-step explanation:
He traveled at 60 mph a distance of 60*hours.
He traveled at 40 mph the same distance of 40(15 hrs - time hrs). The distance is the same; therefore, set them equal.
60t = 40(15-t)
60t = 600 - 40t
100t = 600
t = 6 hrs for the 60 mph day.
15-t = 9 hours for the 40 mph day.
distance = 6 h x 60 mph = 360 miles.
distance = 9 h x 40 mph = 360 miles.
Answer:
C
Step-by-step explanation:
From the box-and-whisker plot, we have
By the definition, the interquartile range is
In your case, the interquartile range is
So, the correct choice is option C.
The weight (y) will always be positive, the number of balls (x) too. So without the bucket, the function would be:
y = 1.6x
Now we have to add the weight of the bucket which is 2lb, or the same 32oz.
So the function results:
y = 1.6x + 32 (oz.)
If there is 1 ball, the weight is 1.6+32 = 33.6 oz. If there are no balls, the weight is 0 + 32 = 32 oz.
It is very important that all terms in the equation are in the same units, oz. in this case. Otherwise, if you do not translate lb. to oz. the resulting equation will be wrong.
If you need the equation expressed in lb., you only need to multiply the equation by 1lb/16oz:
y = = 0.1x + 2 (lb.)
