Determine the equation of the line with slope 3/4 passing through the point 4,0

Vitek1552 [10]

Answer:

$y = \frac{3}{4}x - 3$

Step-by-step explanation:

If it has a slope of 3/4, then it will look like this:

$y = \frac{3}{4}x + b$

If it passes through (4, 0), than y = 0 when x = 4

$y = \frac{3}{4}(4) + b$

$y = 3 + b$

$b = -3$

Therefore, the equation is $y = \frac{3}{4}x - 3$ .

A random sample of 1000 registered voters in Flagstaff found 760 registered voters who support immigration reform. Find a 95% co

dusya [7]

Answer: $(0.7335,\ 0.7865)$

Step-by-step explanation:

Given : A random sample of 1000 registered voters in Flagstaff found 760 registered voters who support immigration reform.

sample size : n= 1000

sample proportion: $\hat{p}=\dfrac{760}{1000}=0.76$

Critical value for 95% confidence interval = $z_{\alpha/2}=1.96$

Confidence interval :

$\hat{p}\pm z_{\alpha/2}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}\\\\=0.76\pm(1.96)\sqrt{\dfrac{0.76(1-0.76)}{1000}}\\\\=0.76\pm0.0264708866493\\\\\approx0.76\pm0.0265\\\\=(0.76-0.0265,\ 0.76+0.0265)=(0.7335,\ 0.7865)$

Hence, the 95% confidence interval for the true percent of registered voters in Flagstaff who support immigration reform: $(0.7335,\ 0.7865)$

the length of a rectangular sing is 4 time its width. if the sign perimeter is 20 inches. what is the sign area ?

Hitman42 [59]

Answer:

Area = 16 in²

Step-by-step explanation:

Represent the length with L and the width with W

We have the following given parameters:

L = 4W

Perimeter = 20

Required

Determine the area.

The perimeter is calculated as thus:

Perimeter = 2(L + W)

Substitute 4W for L and 20 for Perimeter.

20 = 2(4W + W)

20 = 2 * 5W

20 = 10W

Solve for W

W = 20/10

W = 2

Recall that:

L = 4W

L = 4 * 2

L = 8

The area is then calculated as thus:

Area = L * W

Area = 8 * 2

Area = 16

Hence, the area is 16in²

Basile [38]

Answer:

9 is the answer.

Step-by-step explanation:

The Associative Property just moves the parenthesis over so nothing changes.

So 9 goes in the blank spot.
