Suppose that a fashion company determines that the cost, in dollars, of producing x cellphone cases is given by C(x)equalsnegative 0.05 x squared plus 55 x. Find StartFraction Upper C (251 )minus Upper C (250 )Over 251 minus 250 EndFraction , and interpret the significance of this result to the company. StartFraction Upper C (251 )minus Upper C (250 )Over 251 minus 250 EndFraction equals nothing (Simplify your answer.) Interpret the significance of this result to the company. Choose the correct answer below. A. It represents the additional cost to produce one more item after making 250 items. B. It represents the additional cost to produce one item after the fixed costs have been paid. C. It represents the average cost per item to produce 250 items. D. It represents the average cost of producing 251 items.

Which statement best describes the polynomial

In a sample of 2023 u.s. adults, 373 said franklin roosevelt was the best president since world war ii. two u.s. adults are selected at random from the population of all u.s. adults without replacement. assuming the sample is representative of all u.s. adults, complete parts (a) through (d). (a) find the probability that both adults say franklin roosevelt was the best president since world war ii. the probability that both adults say franklin roosevelt was the best president since world war ii is (round to three decimal places as needed.) (b) find the probability that neither adult says franklin roosevelt was the best president since world war ii. the probability that neither adult says franklin roosevelt was the best president since world war ii is (round to three decimal places as needed.) (c) find the probability that at least one of the two adults says franklin roosevelt was the best president since world war ii. the probability that at least one of the two adults says franklin roosevelt was the best president since world war ii is (round to three decimal places as needed.) (d) which of the events can be considered unusual? explain. select all that apply. the event in part left parenthesis a right parenthesis is unusual because its probability is less than or equal to 0.05. the event in part (b) is unusual because its probability is less than or equal to 0.05. none of these events are unusual. the event in part (c) is unusual because its probability is less than or equal to 0.05.
