<em>The expected value of n is 1.152</em>
The question states that ratio of 2n+2 and 2n-2 = 99:7. This means that
2n+2:2n-2 = 99:7, this also means that
= ![\frac{99}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B99%7D%7B7%7D)
If that is so, we can cross multiply so that
99 * (2n - 2) = 7 * (2n + 2), on expanding the bracket, we have
198n - 198 = 14n + 14
198n - 14n = 14 + 198
184n = 212, dividing both sides by 184, we have
n = 212/184
n = 1.152
<u><em>Therefore, the value of n is 1.152</em></u>
