a computer technician charges a flat fee of $35 to repair a computer in addition to an hourly rate of $22.50. the technician has calculated he will earn at least $215 from his next repair job. which inequality can be used to determine the number of hours, h, that the technician will work on his next job?

a
22.5h+35≥215 , with a solution of h≥8

b
22.5h+35> 215 , with a solution of h> 8

c
35h+22.5≥215 , with a solution of h≥5.5

d
35h+22.5> 215 , with a solution of h> 5.5

In a test for esp (extrasensory perception), the experimenter looks at cards that are hidden from the subject. each card contains either a star, a circle, a wave, a cross or a square.(five shapes) as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. when the esp study described above discovers a subject whose performance appears to be better than guessing, the study continues at greater length. the experimenter looks at many cards bearing one of five shapes (star, square, circle, wave, and cross) in an order determined by random numbers. the subject cannot see the experimenter as he looks at each card in turn, in order to avoid any possible nonverbal clues. the answers of a subject who does not have esp should be independent observations, each with probability 1/5 of success. we record 1000 attempts. which of the following assumptions must be met in order to solve this problem? it's reasonable to assume normality 0.8(1000), 0.2(1000)%30 approximately normal 0.8(1000), 0.2(1000)% 10 approximately normal srs it is reasonable to assume the total number of cards is over 10,000 it is reasonable to assume the total number of cards is over 1000
