Aisha organized her books for 1/6 hour and her coin collection for 3/7 hour. What is the best estimate for the total time Aisha spent organizing?

Drag and drop an answer into each box to correctly complete the sentences.

1/6 hour is closest to(0 hours, 1/2 hour, 1 hour, 1 1/2 hour, 2 hours) area. 3/7 hour is closest to(0 hours, 1/2 hour, 1 hour, 1 1/2 hour, 2 hours)area. Therefore, the best estimate for the total time Aisha spent organizing is close to(0 hours, 1/2 hour, 1 hour, 1 1/2 hour, 2 hours)area.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

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.
