Find the nth term of 3,12,27,48,75

Volgvan

Answer:

3n^2

Step-by-step explanation:

3, 12, 27, 48, 75

List the differences between terms:-

9, 15, 21, 27

Now find the second differences:-

6, 6, 6

The sequence in the question is quadratic and the first coefficient ( that of n^2) = 6/2 = 3. The first term in the nth term formula is 3n^2.

Now we write out the original sequence and the 3n^2 values as follows:-

3 12 27 48 75

They are the same so the formula for the nth term is 3n^2.

Answer:

The value of the test statistic is 59.75.

Step-by-step explanation:

The test statistic for the population standard deviation is:

$\chi^2 = \frac{n-1}{\sigma_0^2}s^2$

In which n is the sample size, $\sigma_0$ is the value tested and s is the sample standard deviation.

A sample of 45 bottles of soft drink showed a variance of 1.1 in their contents.

This means that $n = 45, s^2 = 1.1$

The process engineer wants to determine whether or not the standard deviation of the population is significantly different from 0.9 ounces.

0.9 is the value tested, so $\sigma_0 = 0.9, \sigma_0^2 = 0.81$

What is the value of the test statistic

$\chi^2 = \frac{n-1}{\sigma_0^2}s^2$

$\chi^2 = \frac{44}{0.81}1.1 = 59.75$

The value of the test statistic is 59.75.
