P(<100) = P((new or change) & <100) = P(new & <100) + P(change & <100)
... = P(<100 | new)*P(new) + P(<100 | change)*P(change)
... = 0.90*0.70 + 0.20*0.30
... = 0.63 + 0.06 = 0.69 . . . . probability of completing a transaction in < 100 ms

![\boxed{Width \ = \ 31\frac{19}{91} \ Ft^{2}}](https://tex.z-dn.net/?f=%5Cboxed%7BWidth%20%5C%20%3D%20%5C%2031%5Cfrac%7B19%7D%7B91%7D%20%5C%20Ft%5E%7B2%7D%7D)
[ Explanation ]
Area = 1420
Width = ![45\frac{1}{2}](https://tex.z-dn.net/?f=45%5Cfrac%7B1%7D%7B2%7D)
Area For Rectangle: Length · Width
Use division to find width:
1420 ÷ ![45\frac{1}{2}](https://tex.z-dn.net/?f=45%5Cfrac%7B1%7D%7B2%7D)
Convert mixed numbers to fractions:
1420 = ![\frac{1420}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B1420%7D%7B1%7D)
= ![\frac{91}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B91%7D%7B2%7D)
÷ ![\frac{91}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B91%7D%7B2%7D)
Use mixed multiplication:
![\frac{1420*2}{1*91}](https://tex.z-dn.net/?f=%5Cfrac%7B1420%2A2%7D%7B1%2A91%7D)
= ![\frac{2140}{91}](https://tex.z-dn.net/?f=%5Cfrac%7B2140%7D%7B91%7D)
Simplify:
= ![31\frac{19}{91}](https://tex.z-dn.net/?f=31%5Cfrac%7B19%7D%7B91%7D)
