Use the payoff matrix to determine the best strategy.A computer manufacturer must decide whether or not to market a new product. The new product may or may not be better than the old product. If they market the new product and it is better than the old product, their sales should increase. If they market the new product and it is not better, they will lose money to competitors. If they do not market the new product, they will lose to competitors if it is actually better and will lose just the research costs if it is not better. The manufacturer estimates that the payoff matrix is as follows: New Product BetterNot Better src="https://sciemce.com/media/4/ppg__tttt0625191052__f1q53g2.jpg" style="vertical-align: -15.0px;" />The manufacturer believes that the probability that the new product is better is 0.1. What is the best strategy?
A. Wait and see what the competitors do
B. Do not market the new product
C. Market the new product
Write a formula for the general term (the nth term) of the arithmetic sequence. Then use the formula for an to find a20, the 20th term of the sequence.an = an-1 + 10, a1 = 13
A. an = 10n + 3, a20 = 203 B. an = 10n + 23, a20 = 223 C. an = 3n + 10, a20 = 70 D. an = 13n - 3, a20 = 257
