What range of lengths covers almost all (99.7%) of this distribution?

3 standard deviations away from the mean covers 99.7% of all data.

By definition, this is how likely something is to fall in this range, with just over .1% being over 3 standard deviations away and just over .1% being under.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
