Answer:
A population is defined as the data set which consists of all members of a specified group and the sample contains a part or a subset of a population.
For example : all the students of a school are population. But out of all, how many students play sports is a sample.
Hence, the answer is - A population is the complete group under study. A sample is the sub-collection of members of the population from which data are actually collected.
Answer:
There is no question stated. If one assume the question is "Does the probability of picking the same color pen change after the first try?," the answer is "No."
Step-by-step explanation:
When the pen is replaced, the probability reverts back to the original value:
There are 7 pens:
5 Blue
2 Red
The probability of picking a red or blue pen on the first try is:
Red = 2/7
Blue = 5/7
When the pen is replaced, the probabilities return to the original values.
If I understand your question correctly then it's simple all you have to do is use the numbers in the place of the b and c so the question would be what is 8-7 which equals 1
Answer:
The First one: f(-2) a. 9
good luck!
