Eth wants to know the average value of a card in a standard 52-card deck. She sets the value of aces to 1, jacks, queens, and kings to 10, and all other cards to their face value. She picks a single card from the deck, records its value, and shuffles the deck before picking again. She does 5 trials on Monday, 10 trials on Tuesday, and so on, until her final set of 25 trials on Friday. Knowing that the actual average value of a card is 6.5, what can you conclude from this table?

answer: #1 ads up by 8 and i don't know #2

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.
