Answer:

m= 1/4

Step-by-step explanation:

1) Take two points. Let's use the first and second. Subtract one y coordinate from the other. 6 - 5 = 1

2) Do the same process with the x coordinates. 0 - -4 = 4 (0 + 4)

3) Make the answer from the y coordinates the numerator and the answer from the x coordinates the denominator, and you have your final answer: 1/4

What is the approximate circumference of the circle shown below?

Crank

Answer

Formula

$Circumference\ of\ circle = 2\pi r$

where r is the radius of a circle.

As shown in the image

Diameter of the circle = 16 .3 cm

$Radius\ of\ the\ circle = \frac{16.3}{2}$

= 8.15 cm

Put in the formula

$Circumference\ of\ circle = 2\pi\times 8.15$

$\pi = 3.14$

$Circumference\ of\ circle = 2\times 3.14\times 8.15$

= 51.2 cm (approx)

Therefore the circumference of a circle is 51.2cm (approx) .

Option (D) is correct .

Impossible question for me plz help

klio [65]

Answer:

The line x = 3 is simply a vertical line that passes through every single point where x is equal to 3.

One that is is parallel and passes through (-4, 7) will be in the same format, just with another number. The given point has an x-coordinate of -4, so the line is:

x = -4

Use the sample data and confidence level to construct the confidence interval estimate of the population proportion p. n equals

Alekssandra [29.7K]

Answer:

(0.767,0.833)

Step-by-step explanation:

The 95% confidence interval for population proportion p can be computed as

$p-z_{\frac{\alpha }{2} } \sqrt{\frac{pq}{n} }$

The z-value associated with 95% confidence level is 1.96.

whereas p=x/n

We are given that x=440 and n=550.

p=440/550=0.8

$0.8-1.96\sqrt{\frac{0.8(0.2)}{550} }$

$0.8-1.96\sqrt{\frac{0.16}{550} }$

$0.8-1.96\sqrt{0.00029 }$

$0.8-1.96(0.01706)$

$0.8-0.03343$

$0.76657$

Thus, the required confidence interval is

0.767<P<0.833 (rounded to 3 decimal places)

Hence, we are 95% confident that our true population proportion will lie in the interval (0.767,0.833)
