Best ResponseYou've already chosen the best response.1hold on  i got it now

Best ResponseYou've already chosen the best response.1for the first one Add up all the numbers and divide by 7 to get the mean for the median arrange them in ascending order. The median will be the middle value ( in this case the 4th value)

Best ResponseYou've already chosen the best response.0then I dont know what you mean by saying 4th for median

Best ResponseYou've already chosen the best response.1yes 0 i mean the 4th number in the list 3 4 6 7 9 9 11

Best ResponseYou've already chosen the best response.0oh so it would be mean= 7 and median = 7

welshfella

Best ResponseYou've already chosen the best response.1the middle number = 7 that is the median

welshfella

Best ResponseYou've already chosen the best response.1so here the mean and the median are equal

Best ResponseYou've already chosen the best response.0cool, power OS the welsh minds

Best ResponseYou've already chosen the best response.0now the second question is gonna be over our heads

welshfella

Best ResponseYou've already chosen the best response.1yea well we need to keep the median and the mean equal to 7 This will give us a total of 8 numbers and the only way to make the mean and median equal is to add another 7

Best ResponseYou've already chosen the best response.0Alright so you think you'd add another 7, gotcha

Best ResponseYou've already chosen the best response.1if there is an total of numbers the median is the mean of the 'middle two'.

Best ResponseYou've already chosen the best response.1* an even total' i meant to say

Best ResponseYou've already chosen the best response.1if you add up the 8 numbers it gives 56 so mean = 56/8 = 7

Best ResponseYou've already chosen the best response.0that makes sense ^

Best ResponseYou've already chosen the best response.1for the third one If we add an extra number at the end it makes the median 8  because the middle 2 values will now be 7 and 9  do you see that?

HowardWolowitz

Best ResponseYou've already chosen the best response.0so you saying add a 8

HowardWolowitz

Best ResponseYou've already chosen the best response.0and that would even it out

Best ResponseYou've already chosen the best response.0ok, that makes it senseible

Best ResponseYou've already chosen the best response.1So the number I've marked X must be high enough to make the mean greater than 8 what number to you think we can make X/

welshfella

Best ResponseYou've already chosen the best response.1we'll have b numbers and total / 8 must be greater than 8

HowardWolowitz

Best ResponseYou've already chosen the best response.0so it could be any number greater then 8 but not 9

welshfella

Best ResponseYou've already chosen the best response.1no  the total will b 49 + X right ?

HowardWolowitz
 one year ago
Best ResponseYou've already chosen the best response.0no I thought 49 + 7

HowardWolowitz

Best ResponseYou've already chosen the best response.0nvm I was thinking division

welshfella

Best ResponseYou've already chosen the best response.1no X is an other number

welshfella

Best ResponseYou've already chosen the best response.1what we must do is solve the inequlaity X + 49  > 8 8 x + 49 > 64

welshfella

Best ResponseYou've already chosen the best response.1(x + 49)/ 8 is the new mean and this has to be > 8

welshfella

Best ResponseYou've already chosen the best response.1right so a valid number would be 16

HowardWolowitz

Best ResponseYou've already chosen the best response.0hmmm, interesting cause I would of never of gotten bymyself... power of the welsh minds

welshfella

Best ResponseYou've already chosen the best response.1yes 16 is the number to be added
