12.1 arithmetic sequences algebra 2 volume 2 answers
1 answer:
An example of 12.1 arithmetic sequences algebra 2 question is Find the sum of the arithmetic series given as 1,2,3…..99,100.
<h3>What is Arithmetic sequences?</h3>An arithmetic sequence is known to be a group or sequence of numbers that is said to be the difference that exist between any two successive members of the sequence and it is a constant.
To find the sequence, one was given a total of 100 values:
So n=100.
first value = 1
Last = 100.
=100/2 (1+100)= 5050
Therefore the answer is 5050

There are different variations in population size. The best reason why the simulation of the sampling distribution is not approximately normal is that The sample size was not sufficiently large.
<h3>What takes place if a sample size is not big enough? </h3>- When a sample size taken by a person or a researcher is not big or inadequate for the alpha level and also analyses that one have chosen to do, it will limit the study statistical power.
Due to the above, the ability to know a statistical effect in one's sample if the effect are present in the population is greatly reduces.
