Which of these statement accurately describes Chebychev's Inequality? For a data set, the proportion of values in the range “average ± z SDs” is

at least 1−1z2/

That the standard deviation is greater than the mean.

For a data set, the proportion of values in the range “average ± z SDs” is never more than 1−1z2/

That the mean is always greater than twice the median of a data set.

do you have a picture of the table

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
