Bases:
6*3/2= 9 in^2 each
9*2=18 in^2 for both bases

Sides:
(6+5+5)*12
16*12= 192 in^2 for all the sides

Add
192+18= 210 in^2

Final answer: 210 in^2 of tile needed

Write the following equation in Slope-Intercept form:<br>-3x + 4y = 8

myrzilka [38]

$- 3x + 4y = 8 \\ 4y = 3x + 8 \\ \frac{4y}{4} = \frac{3x + 8}{4} \\ y = \frac{3}{4}x + 2$

A certain region would like to estimate the proportion of voters who intend to participate in upcoming elections. A pilot sample

sweet [91]

Answer: 183

Step-by-step explanation:

Given : A pilot sample of 50 voters found that 33 of them intended to vote in the election.

i.e. $\hat{p}=\dfrac{33}{50}=0.66$

and the voters sampled = 50

Significance level : $\alpha=1-0.99=0.01$

Critical value : $z_{\alpha/2}=2.576$

Margin of error:E = 0.08

The formula to find the sample size is given by :-

$n=\hat{p}(1-\hat{p})(\dfrac{z_{\alpha/2}}{E})^2\\\\\Rightarrow\ n=0.66(1-0.66)(\dfrac{2.576}{0.08})^2\\\\=232.666896\approx233$

Then, the additional voters need to be sample = $233-50=183$

Hence, the region should sample 183 additional voters.

Consider the line y = - 9x + 6 . Find the equation of the line that is perpendicular to this line and passes through the point (

gregori [183]

The picture is illegible.

Slope of line y = -9x+6 is -9
Slope of any perpendicular to line is -1/9

Point-slope equation for line of slope -1/9 that passes through (3,5):
y-5 = (-1/9)(x-3)

The equation can rearranged to slope-intercept form or standard form. (Since I can’t read the picture, I don’t know what form of equation is needed.)

I need an answer for the attachment below:

kirza4 [7]

Answer:

Step-by-step explanation:

The line passes through points ( - 1 , 2 ) and ( 3 , 1 )

Let there points be A and B

A ( -1 , 2 ) -----> ( x1 , y1 )

B ( 3 , 1 ) -------> ( x2 , y2 )

Now, Let's find the gradient ( slope)

$\frac{y2 - y1}{x2 - x1}$

plug the values

$= \frac{1 - 2}{3 - ( - 1)}$

Calculate the difference

$= \frac{ - 1}{3 - ( - 1)}$

When there is a (-) in front of an expression in parentheses, change the sign of each term in the expression

$= \frac{ - 1}{3 + 1}$

Add the numbers

$= \frac{ - 1}{4}$

Use $\frac{ - a}{b} = \frac{a}{ - b} = - \frac{a}{b}$ , to rewrite the fraction

$= - \frac{1}{4}$

Hope this helps...

Best regards!!
