Answer:
The correct option is d) convenience sample
Step-by-step explanation:
In statistics, we use different sampling techniques to gather a chunk of sample data from a very large population.
There are many sampling techniques and out of them one is convenience sampling.
Convenience Sampling:
The convenience sampling is defined as the sample data which is readily and conveniently available.
Examples:
1. Asking people questions at a place that is convenient for you.
2. Asking your friends or family members
3. A college student asking for student's opinion at the college who is surveying for his thesis.
In the given scenario, Kristen Ashford has list of 5,000 subscribers for Wind Surfing magazine. She chooses the first 100 of the 5,000 names, this is clearly a convenient sample since the sample is easily, readily and conveniently available.
If she had selected 100 names randomly then it would have been called random sampling but in this case, she simply selected the first 100 names for the sake of convenience therefore, it is a convenience sample.
Answer:
c
Step-by-step explanation:
The distance of the car from the stop sign, d , in feet, at time t , in seconds, can be found using the equation
The average rate of change of a function f(x) on [a,b] is
We need to find the average speed of the car, in feet per second, between t=2 and t=5.
At t=2,
At t=5,
The average speed of the car, in feet per second, between t=2 and t=5 is
The average speed of the car, in feet per second, between t=2 and t=5 is 7.7 feet per second.
