we are given

$8x^4+7x^3+5x^2+8$

we know that this is polynomial

When number of terms >3 ....then we call that as "polynomial"

We can see that

number of terms =4

so, this is "polynomial of 4 terms"........Answer

Answer:

This is a polynomial.

Step-by-step explanation:

A monomial is a constant, a variable or the product of constants and variables.

A binomial is the sum or difference of two monomials.

A trinomial is the sum or difference of three monomials.

Anything more than three terms makes it a polynomial.

This has 4 terms; thus it is a polynomial.

ANTONII [103]

Answer:

$32.9-2.365\frac{4.9}{\sqrt{8}}=28.80$

$32.9+2.365\frac{4.9}{\sqrt{8}}=37.00$

Step-by-step explanation:

Information given

$\bar X=32.9$ represent the sample mean for the sample

$\mu$ population mean (variable of interest)

s=4.9 represent the sample standard deviation

n=8 represent the sample size

Confidence interval

The confidence interval for the mean is given by the following formula:

$\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}$ (1)

the degrees of freedom are given by:

$df=n-1=8-1=7$

Since the Confidence is 0.95 or 95%, the value of $\alpha=0.05$ and $\alpha/2 =0.025$ , and the critical value for this cae would be $t_{\alpha/2}=2.365$

Now we have everything in order to replace into formula (1):

$32.9-2.365\frac{4.9}{\sqrt{8}}=28.80$

$32.9+2.365\frac{4.9}{\sqrt{8}}=37.00$
