A²-b²=(a-b)(a+b)

so if (x+8) is a factor then (x-8) is also a factor

so
(x+8)(x-8)=x²-8²=x²-64

the blank is 64

#1: Write the equation of the graphed line. NO SPACES, ALL LOWERCASE. <br> Please help

ivanzaharov [21]

Answer:

Equation of graphed line is $\mathbf{y=\frac{2}{3}x-3}$

Step-by-step explanation:

We need to write the equation of the graphed line.

The equation will be in slope intercept form $y=mx+b$ where m is slope and b is y-intercept

We need to find slope and y-intercept.

Finding slope

Slope can be found using formula: $Slope=\frac{y_2-y_1}{x_2-x_1}$

We will use points (0,-3) and (3,2)

Looking at the graph, we get $x_1=0, y_1=-3, x_2=3, y_2=-1$

Putting values in graph and finding slope

$Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-1-(-3)}{3-0} \\Slope=\frac{-1+3}{3} \\Slope=\frac{2}{3}$

So, we get slope $\mathbf{\frac{2}{3} }$

Finding y-intercept

y-intercept can be found when x is zero.

So, looking at graph, when x =0, y=-3

So, y-intercept is -3

Equation of Line

So, equation of line having slope $\mathbf{\frac{2}{3} }$ and y-intercept b = -3

$y=mx+b\\y=\frac{2}{3}x-3$

So, Equation of graphed line is $\mathbf{y=\frac{2}{3}x-3}$

A researcher conducted an Internet survey of 500 students at a particular college to estimate the average amount of money studen

bonufazy [111]

Answer:

The margin of error is $ME = 2.2962$

Step-by-step explanation:

From the question we are told that

The number of student is $n = 500$

The highest amount is $A =$ $200

The lowest amount is $B =$ $75

The sample mean is $x =$ &140

The Standard deviation of this set is mathematically evaluated as

$s = \frac{A-B}{4}$

Substituting values

$s = \frac{200-75}{4}$

$s = 31.25$

The margin of error (ME) is mathematically evaluated as

$ME = t_{n-1}__{\alpha }} * \frac{s}{\sqrt{n} }$

Where $t_{n-1}__{\alpha }}$ is the critical value for $\alpha = 0.05$ i.e the significance level

From the critical value table this is $t_{n-1}__{\alpha }} = 1.649$

$ME = 1.649 * \frac{31.25}{\sqrt{500} }$

$ME = 2.2962$
