Let x be the rate of the slower bicyclist and
x + 4 be the rate of the faster bicyclist
Since the bicyclists are headed towards opposite directions, the sum of the distances they covered traveling for one hour and 15 minutes should be equal to 40 km based on the given conditions above. This may be expressed as,
(x)(1.25) + (x + 4)(1.25) = 40
Calculating gives x = 14
Thus, the rate of the bicyclists are 14 km/h and 18 km/h.
Answer:
0.72 or 0.72866953788 0.7 0.72866953788
Anything to the power of 0 is one.
Therefore we have:
(1)(y^-7z)
Which simplifies to:
y^-7z
find prime factors to get the inbetween numbers for product, and choose the one that has a difference of 20, and it should be 5 and 25, both requirements are met.
Answer:
Cluster sampling
No
Step-by-step explanation:
Missing part of Question
Find:
a) Which type of sample is this?
b) Is it the correct choice ?
Solution:
- Simple random sample is the one in which every individual would have equal chance of being selected.
- Stratified random sample draws simple random sample from the independent sub-groups.
- Systematic sampling is letting every kth individual be in the sample ( k as an integer )
- Convenience sampling is used for example voluntary response or a sub-group from the population.
a)
Cluster sampling was used in our case because one of all the teams were chosen and this entire team is in this sample.
b)
No. This method has limitation of giving us a shortsighted view which lacks the overview on the use of performance-enhancing drugs, we can only use this sample to draw conclusions on the team.
