We have the operation:
(2n² + 1)/3
2n (n/3) + 1/3
Since we are to use the condition that 3 does not divide n, we have:
n/3 = q +r/3
n = 3q + r
where q is the quotient and r is the remainder and not divisible by 3 or equal to 0
both q and r are whole numbers
Substituting,
2(3q + r) (q + r/3) + 1/3
6q² + 4qr + 2r²/3 + 1/3
6q² + 4qr + (2r² + 1)/3
The term:
(2r² + 1)/3
will only be a whole number if r is not divisible by 3 or equal to 0, which means that
(2n² + 1)/3
is a whole number if and only if
n/3 is not a whole number
I gotchu! there is no association shown between the two in this sample because the given information only shows the correlation between fur color and environmental and NOT gender.
hope you do amazing have a wonderful night
