Answer:

- 2k - {k}^{2} + 4 {k}^{3}

Step-by-step explanation:

According to the Product-to-Power Exponential Rule, whenever you multiply terms with exponents and coefficients, you add the exponents:

-k[-4k² + k + 2]

4k³ - k² -2k

The above answer is written in reverse, but it is the exact same result.

I am joyous to assist you anytime.

ipn [44]

Answer:

The standard error of the sample mean is _17.677_ psi.

Step-by-step explanation:

<u>Explanation</u>:-

A random sample of n = 8 specimens is collected.

Given sample size is n = 8

Given mean of the population 'μ' = 2500 psi

standard deviation 'σ' = 50 psi

Let x⁻ is the mean of the observed sample

Standard error of the sample mean = \frac{S.D}{\sqrt{n} }      ...(i)

Given Population of standard error (S.D) 'σ' = 50 psi

Now substitute all values in (i)

S.E = \frac{50}{\sqrt{8} } =17.677

<u>Conclusion</u>:-

The standard error of the sample mean is _17.677psi.
