Which of the following scenarios demonstrates the replication of a scientific investigation?
OA
Dr. Abraham performs the same experiment in his own laboratory on five different occasions.
OB. Dr. Burgess reads about an experiment in a scientific journal. He performs a similar investigation in his own laboratory,
but he changes some of the variables.
OC. Dr. Kim performs an experiment in her laboratory. Then, Dr. Stevens performs the same experiment in his laboratory to
verify the results
OD
Dr. Jordan visits another scientist and watches the scientist perform an experiment in her own laboratory

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
