Given that 8% of the students are Swedish, this means that 100 - 8 = 92% are not Swedish.
Let S represent the event that a student is Swedish and N represent the event that a student is not a Swedish.
Then, the probability that a student chosen at random is a Swedish, P(S), = 8% = 0.08
The probability that a student chosen at random is not a Swedish, P(N), = 92% = 0.92
That the first Swedish person found was on the third trial means that the first and second trial produced a non-Swedish.
Therefore, the required probability = 0.92 x 0.92 x 0.08 = 0.068 to three decimal places.
Both of these are linear functions:
Distance A is d=2.5h and is proportional to time because the distance is just 2.5 times however many hours you have traveled.
Distance B is d= 2(h-1) + 4. This is not proportional to time but it is a linear function.
Answer:
150 pages
Step-by-step explanation:
want to read 2,000 pages
already read 1,250 pages
Number of pages left to read
= 2000-1250
= 750
Rest of the reading spread over 5 weeks
wants to read same number of pages each week
Number of pages that need to be read each week over 5 weeks
= Number of pages left to read / total number of weeks
=750 / 5
= 150
He will need to read 150 pages a week.
Answer:
I think c
Step-by-step explanation:
6 3/5 - 2 1/4 = 87/20 = 4 7/20 = 4.35
so 4 7/20 is right
hope this helps
