Answer: SIMPLIFY TERMS === 32X^3-12X^2+51X=35

Step-by-step explanation:

(4x2+x+7)(8x−5)

Expand (4x2+x+7)(8x−5)

by multiplying each term in the first expression by each term in the second expression.

4x2(8x)+4x2⋅−5+(x(8x)+x⋅−5)+(7(8x)+7⋅−5)

Simplify terms.

➷Multiply everything together

(4x2+x+7)(8x−5)

=(4x2+x+7)(8x+−5)

=(4x2)(8x)+(4x2)(−5)+(x)(8x)+(x)(−5)+(7)(8x)+(7)(−5)

=32x3−20x2+8x2−5x+56x−35

=32x3−12x2+51x−35

Final answer:

32x3−12x2+51x−35

A defunct website listed the "average" annual income for Florida as $35,031. What is the role of the term average in statisti

ahrayia [7]

Answer:

For this case the average is an statistic unbiased for the population parameter $\mu$

And the average is calculated with the following formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

Where n represent the sample size

N represent the population size, and X the observations for this case the annual income.

This statistic is an unbiased estimator of the population mean since $E(\bar X) = \mu$

After calculate the average they got:

$\bar X= 35031$

And we can use the term "sample mean" instead of the average, and is a measure of central tendency for the data
