A balloon holds 2 cubic feet of air. The balloon is blown up larger to hold 6 cubic feet of air. What is the percent of change for the volume of air inside
the balloon?

Initially 4.2 cubic feet,

Blown to 5.6 cubic feet,

% Change =  (5.6 - 4.2) / 4.2      * 100%

                  = 1.4/4.2 *  100%

                  = 1/3 * 100%

                  = 100/3  %

                   = 33    1/3  %

I hope this helps.

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.
