'Two sailboats are traveling along the same path away from a dock, beginning from different locations at the same
time. John's boat begins 30 miles from the dock and is 50
miles from the dock after 5 hours. The distance of
Roberta's boat from the dock is represented by the
function y = 5x + 25, where x represents time and y
represents the distance from the dock.
Which boat was farther from the dock at the beginning, and which traveled
more quickly?
O A. Roberta's boat was farther from the dock at the beginning, but
John's boat traveled more quickly.
B. John's boat was farther from the dock at the beginning, but
Roberta's boat traveled more quickly.
C. John's boat was farther from the dock at the beginning, and it
traveled more quickly.
D. Roberta's boat was farther from the dock at the beginning, and it
traveled more quickly.

just took the test and my answers down below!

ok so what's the question?

step-by-step explanation:

0 and 5 minutes

step-by-step explanation:

given that one morning eight buses arrive late by the number of minutes given below:

0 8 2 6 9 2 0 7 8

write these in ascending order

0   0 2 6 7 8 8 9

in the afternoon two more buses arrive at the bus stop say by x and y minutes late.

total number of buses = 10

median = average of 4th and 5th after arranging in ascending order

since 4th entry is 6, the values of x and y should be below 6

also given 0 is the mode so either x or y or both should be 0 because then only 0 gets the maximum frequency and hence mode

thus we have

0 0 0 2 6 7 8 8 9 and another unknown entry which is below 6.

since median is 3.5, we have the unknown entry to be 5 only because then only median =( 2+5)/2

thus the after noon buses were late by 0 and 5 minutes.
