8500:78=
100times 7800 that it is less than 8500
So 8500-7800=700
Again you think how many 78 are in 700 it is enough you guess
8 times 78 is 624
Good job
700-624=76 that it is less than 78
So, 100+8=108
And reminder is 76
8500= 108.78+76
Step-by-step explanation:
write what you know
the flat fee doesnt chamge no matter how much he uses his data
the charge for every gigabyte does change
Ex: if he uses 3 gigabytes of data in one month, that's
5 + 5 + 5 = $5 x 3 = $15
So taking this into consideration youd write the following
$41.50 + $5x = $52.50 (since this is what we want to equal)
then solve for x

Step-by-step explanation:
Given that a researcher is looking for 10 people to participate to a medical study on diabetes.
Suppose the researcher has to find his 10 participants, out of 25, then he has to get 9 participants in 24 trials, and the last one in 25th trial
Out of 24 trials, 9 participants selecting is binomial with p =0.1 because there are only two outcomes and each trial is independent of the other.
Hence Prob for selecting 9 from 24 = Prob for 9 successes in 24 trials
=P(X=9)
= ...i
the probability that the researcher will have to call 25 candidates in order to find his 10 participants
= i * prob for 25th trial success
=
