Answer:
B and C
Step-by-step explanation:
Minimum and Maximum points occur when the gradient of the function is equal to 0. Graphically this looks like a bend such that the function dips from decreasing to increasing (the gradient goes form being negative to positive) and vice versa.
A minimum point occurs where all the nearby values are higher than that of the point in question.
A maximum point occurs where all the nearby points are lower than the point in question.
By looking at the graph, there is a maximum point around (4.5, 1.5) which is consistent with B but not A (since A talks about a minimum point)
By looking at the graph, there is a minimum point around (0.5, 1.5) which is consistent with C.
I've highlighted areas of interest below so hopefully that's helpful :>
I would say the answer is 7, since 21 divided by 3 is 7 and there are 1/3 as many of them
Answer:
x = 2
Step-by-step explanation:
Answer:
It is a random sample
The second sample is more representative of a population
The second sample gives better representation because it is larger
Step-by-step explanation:
According to the given statement we have been given two statements and we have to determine how often people in a community listen to the local radio station each month.
If you notice the second sample it is a random sample because people who visited the store had equal probability of being chosen.
The second sample is more representative of a population because it is a larger sample than the first sample and the sample are taken from the only local grocery store.
The second sample gives better representation because it is larger ...
