so if there is an equation and it says for example: D + AB or U + ZS or something. if it has 2 lettera nzt to eachother would you multiply/add those 2 numbers togather? or make it one number. like if A is 4 and B is 5. would you multiply 4 x 5 or do 45??​

step-by-step explanation:

one set of data has more variation than the other. hope this !

inverse operation of addition

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.
