Answer:
Yes, Sample is good.
Step-by-step explanation:
The sample is a subset of the population, we take a sample because sometimes it is not possible to work on the whole population or it is quite costly or the time has taken so we work on sample.
Characteristics of Good Sample:
- The choice of the sample should be unbiased that means there should be an equal chance of selecting each unit.
2. It should be representative of the sample.
3. The choice of the sample should be flexible.
Since here she did not do any bias in selecting a sample. Here the choice of sample is independent and each unit has an equal chance of being selected in a sample. So, the choice of sample is quite good.
Answer:
16.7
Step-by-step explanation:
speed is constant at 17 mph
Distance covered after one hour = 17 miles
Distance between port and San Francisco = 3 miles
Speed at which distance changes 1 hour after leaving port :
r² = 17² - 3²
r² = 289 - 9
r = √280
r = 16.733
= 16.7 (nearest tenth )

Since there is no denominator or anything under a square root, which are the two limits to domain, your domain would be (-infinity, infinity), and your range would be (-infinity, infinity)
