During an experiment, readings for blood pressure in a person’s body were found to be constant. however, when measured by a different blood pressure cuff, the readings differed by 15 points for each reading. this difference indicates that the results are

Most likely means that the results are inconclusive or that the second blood pressure cuff is faulty.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

carbon atoms, hydrogen, oxygen, and nitrogen.
