You plot the points and use the distance formula to find the length of the lines between the points. Distance formula: d= $\sqrt{(}x_{2} -x_{1} )^2 + (}y_{2} -y_{1} )^2\\$

Then use the pythagorean theorem with the sides, (C^2=A^2+B^2, c=longest side) if the equation works then it is a right triangle.

Is an imaginary "line" from the Earth to the Moon a line, a ray, or a segment? and WHY?

sesenic [268]

Answer:

Segment

Step-by-step explanation:

It is a segment because it has two endpoints (the Earth and Moon). If it was a ray, it would go on forever in one direction. It doesn't, so the imaginary line is a segment.

The first image is a segment, the second is a ray.

Hope this helps. :)

A test consists of 100 multiple choice questions, each with five possible answers, only one of which is correct. Find the mean a

TEA [102]

Answer: Mean = 20 and standard deviation = 4

Step-by-step explanation:

Let x represents the success of getting the correct answer.

Here, the total number of trials(n) = 100

The probability of getting the correct answer, p = 1/5

Thus, the mean of the number of correct answer,

$\mu_x= np$

$\mu_x= 100\times 1/5$

$\mu_x= 20$

Now, the standard deviation, $\sigma_x= \sqrt{n\times p\times (1-p)}$

$\sigma_x= \sqrt{100\times 1/5\times 4/5}$

$\sigma_x= \sqrt{16}$

$\sigma_x= 4$

Thus, First option is correct.
