Answer:

$6x^5-5x^4+6x^3-x^2+12x+-31$

Step-by-step explanation:

The question is to simplify (add) the expression shown below:

$(-5x^4+6x^3-43)+(6x^5-x^2+12x+12)$

We can get rid of the parenthesis and add like terms:

$(-5x^4+6x^3-43)+(6x^5-x^2+12x+12)\\=-5x^4+6x^3-43+6x^5-x^2+12x+12\\=6x^5-5x^4+6x^3-x^2+12x+12-43\\=6x^5-5x^4+6x^3-x^2+12x+-31$

standard form means to keep the terms in descending order of powers, which is already shown.

A random sample of 121 bottles of cologne showed an average content of 4 ounces. It is known that the standard deviation of the

pychu [463]

Answer:

Standard error of the mean parameter the average content of colognes

S.E = 0.02 ounces

Step-by-step explanation:

Explanation:-

Size of random sample 'n' = 121 bottles

mean of the sample $x^{-} = 4$ ounces

Standard deviation of Population

σ = 0.22

Standard error of the mean parameter the average content of colognes

$S.E = \frac{S.D}{\sqrt{n} }$

$S.E = \frac{S.D}{\sqrt{n} } = \frac{0.22}{\sqrt{121} }$

S.E = 0.02

Final answer:-

Standard error of the mean parameter the average content of colognes

S.E = 0.02 ounces
