Determine whether the statement below is true or false. If it is true, explain why it is true. If it is false, give an example to show why it is false. The numbers 4, 9, and 12 are written separately on three pieces of paper. These slips of paper are then placed in a bowl. If you draw two slips from the bowl, one at a time, without replacement, then the sample space for this experiment consists of six elements. True. The sample space is S = {(4,4), (9,9), (12,12), (4,9), (4,12), (9,12)}. True. The sample space is S = {(4,9), (4,12), (9,4), (9,12), (12,4), (12,9)}. False. The sample space is S = {(4,4), (9,9), (12,12), (4,9), (4,12), (9,4), (9,12), (12,4), (12,9)}. False. The sample space is S = {4, 9, 12}. False. The sample space is S = {(4,9), (4,12), (9,12)}.

Use the forward finite difference method to estimate the first derivative of f(x) = 5.4x^4 -0.12 x^3 + 2x^2 – 0.5x +1.7 at x =0.25, using a step size of h =0.5 and then with a step size of 0.125. Explicitly calculate the derivative. Then calculate the absolute relative true percent error for each step size. 5 points

As part of a promotion for a new type of cracker, free trial samples are offered to shoppers in a local supermarket. The probability that a shopper will buy a packet of crackers after tasting the free sample is 0.200. Different shoppers can be regarded as independent trials. If X is the number among the next 100 shoppers who buy a packet of crackers after tasting a free sample, then X has approximately anN(20, 4) distribution.N(20, 16) distribution.N(0.2, 16) distributio
