1. ### Use a linear approximation (or differentials) to estimate the given number. (Use the linearization of 1/x. Do?

f(x) = 1/x ----> f '(x) = -1/x^2 1/99 is approximately 1/100 so close to this the gradient of the tangent is -1...approx= 1/100 + 0.0001 = 0.0101 Edit. A calculator will of course confirm that 1/99 = 0.010101010101.......

2. ### lottery probability!!!?

...to pick from and we need to pick 6.... also with a lottery order of numbers does not matter. 99!/(6!*(99-6)!) will give us our answer = 99*98*97*96*95...

3. ### I HAVE NO IDEA WHAT THESE PROBABILITY QUESTIONS MEAN?

...does not have cancer, so 1% of 99.8% = 0.998% ≈ 1% 2. prob( not L) we did in 1, 99.8%. by the way, you lose a lot of accuracy if you round off your...

5. ### where does the \$1 dissappear?

What are you doing with 49+49+1? It doesn't make sense to do that, let alone expecting it to equal 100. It should be 49 + 49 − 1 = 97. Anyway, if you don't have money, then don't buy the shirt.

8. ### is there an easier way to find the sum of these numbers without having to add them one by one?

...!! So I suggest that 1/(1*2) + 1/(2*3) + ..... + 1/(99*100) = 99/100 (See also Scott's formal proof above He...

9. ### can someone explain this math question?

the infinite series 9/10 + 9/100 + 9/1000 ..... = 0.999.... does equal 1. let S = 0.9999.......... then 10S = 9.99999.......... subtract the equations 9S = 9.00000........ S = 1

10. ### How do I complete this table?

..., then this is a really stupid question. f(x) = -0.125 at x = 2, but that does not guarantee that f(x) will be anywhere near -0.125 for close values of x = 2...
