Answer:
x+1
Step-by-step explanation:
Your answer is 560cm^2.
We get this answer first by dividing 96 by 2, because the perimeter is made up of 2 lots of both sides. This gives us 48cm.
Then we find out how long each side is by adding together 5 and 7 to give us 12, and dividing 48 by 12 to give us 4. This is how big each of the 'parts' of the ratio are. Then, we just multiply 4 by 5 to get 20, and 4 by 7 to get 28.
This tells us that 20 and 28 are the side lengths, so we just need to multiply them together to get the area of the rectangle, which gives us 560cm^2.
I hope this helps! Let me know if you have any questions :)
Answer:
0.0000269
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
=
Answer:
Maximum of 14 Hours
Step-by-step explanation:
1500 + h(250) ≤ 5000
1500 + 250h ≤ 5000
250h ≤ 5000 - 1500
250h ≤ 3500
250h/250 ≤ 3500/250
h ≤ 14
