Answer:
Normal (12, 0.20)
Step-by-step explanation:
Given that a population of cats has a population mean of
Also given that the distribution of weights of these cats is fairly symmetrical.
Since sample size is large and a random sample of 100 cats are drawn from this population, we find that
the mean of the sample would follow a normal distribution with mean =population mean and std deviation = population std dev/sqrt n
i.e. Sampling distribution of X would be normal with
mean = 12 pounds
and std deviation =
Answer:
3*2n=6n
3*4=12
And that gets you to the 6n-12
And adding I will Mark you brainliest is a good way to get your answers (though you probably won’t get so much if you keep saying it but never do)
The answer is C
Answer:

Using pythagoras theorem
Answer:
4,374
Explanation:
Given the sequence: 2, 6, 18, ...
If we study the pattern we observe that:
This is a geometric sequence with:
• The first term, a=2
,
• Common Ratio, r=3
The nth term of a geometric sequence is obtained using the formula:
Therefore, the 8th term will be:
The 8th term of the sequence is 4,374.
