Answer:
Megan travelled at 9mph for 6 hours and 7mph for 3 hours
Step-by-step explanation:
Speed = distance / time
Speed*time = distance
Assuming that Megan travelled x hours at 9mph
(9*x) + (7*(9-x)) = 75
x = 6 hours
So Megan travelled at 9mph for 6 hours and 7mph for 3 hours
Answer:
A
Step-by-step explanation:
The teacher will use 3 rolls only to have perfect measurements.
1 yard = 3 feet
4 large bulletin boards are there each needing 9 yards of border.
That means 4 large bulletin boards in total need
9×4 yards of border
= 36 yards of border
= 108 feet of border
Also, there is a small bulletin board that only needs 12 feet border
Hence, in total there is a need for
108 + 12 = 120 feet border.
The border is sold in 40-foot rolls.
Hence, there is a need for 120/40 rolls
i.e. 3 rolls
Hence, the teacher will use 3 rolls only.

The correct option is fourth option
Explanations:
From the data, re-arranging in ascending order, the median of the data is 58.
The upper quartile is 62, while the lower quartile is 54
From the options, only the 4th options represent a box plot of median 58, upper quartile of 62 and lower quartile of 54. This makes it the correct option
