The graph of a straight line y=3x-6 cuts the x-axis and y-axis at points A and B respectively. a) find the coordinates of points A and B
b) find the length of AB
c) M is the midpoint of AB. Find the coordinates of M

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

question 1: step-by-step explanation:

1/4 of 84 = 84÷4= 21

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.
