Answer:
6 kilometers. This is because A,B, and C are all around 18 feet. However, 6 km = 19,685 feet and that is unrealistic.
320-70= 250
250X1/2=125
X=125
If every 10 minutes 3 buses leave then over a course of 60 minutes (1 hour ) 18 buses would leave
Answer:
21/70=x/30
Step-by-step explanation:
Noticing that it is referring to problem b, we head over to that. It states two important pieces of information. Only seventy percent of the players participated, and 21 total played. This means we can simply divide 21 by 7, and multiply by 10. This shows us that there are thirty total players because 21/7 is equal to 3, multiplied by 10 is equal to thirty. 30 minus 21 is equivalent to 9, meaning 9 players did not play. The proportion we would use for this is 21:70 equal to x:30. Cross-multiply, and we get 70x = 630. x = 9, thus proving our answer is correct.
Answer:
Option C
Step-by-step explanation:
For a better, clear and unbiased sampling, choosing randomly might not allow for a biased sampling. Choosing in an alphabetical order might not give a representative of the whole hospitals both private and public, thus invigilator the conclusion of our hypothesis test.
