After spending $43 on groceries and $19 on a book, mrs groom had $16 left how much did mrs. groom have to begin with?

Ok so you add 43 plus 19 and then you get the answer of 62 dollars answer 62$

Mrs Groom had $78 because if you add up 43 and 19 you get 62, and add 16 to that, you get 78. Which means she had $78 to begin with.

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.
