Find the missing endpoint, help

Mathematics
1 answer:
vladimir2022 [97]3 years ago
6 0

Answer:

M = (13, - 6 )

Step-by-step explanation:

The coordinates of the midpoint are the average of the x and y coordinates of the endpoints.

L (- 9, 4 ) , let M = (x, y ) , then

\frac{-9+x}{2} = 2 ( multiply both sides by 2 )

- 9 + x = 4 ( add 9 to both sides )

x = 13

and

\frac{4+y}{2} = - 1 ( multiply both sides by 2 )

4 + y = - 2 ( subtract 4 from both sides )

y = - 6

Then

coordinates of M = (13, - 6 )

<h3>What is standard deviation ?</h3>

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean.

Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

According to the question,

The standard sampling error of the sample mean is σₓ ,

The sampling distribution is: N (u,σₓ/n)

Therefore,

By using the standard deviation formula:

σₓ = √∑(xi -μ)/N

Where,

∑= population standard deviation

N= the size of the population

xi= each value from the population

μ =the population mean

So ,

σₓ = \frac{20.6}{\sqrt{50} } = 2.913

Since, a = 1- 95% = 0.05

therefore Z\frac{a}{2} = (1-0.005 x 2) = 1.959964

Here, the margin of error for a 95% confidence interval for this sample is given by:

Z\frac{a}{2} * σₓ = 1.959964 x 2.913    

           = 5.7099

5.7099 is the margin of error for a 95% confidence interval for this sample.

A line has the equation y = 3x + 16 what are the coordinates of the y intercept of the line?
bearhunter [10]

Answer:

(0, 16)

Step-by-step explanation:

  • y = 3x + 16

  • Plug x = 0

  • -> y = 3*0 + 16

  • -> y = 0 + 16

  • -> y = 16

  • -> y- intercept = (0, 16)

Distributive Property Using GCF<br><br> 25 + 30
postnew [5]

Hey there! I'm happy to help!

Let's look at the factors of each of these numbers.

25

1,25

5,5

30

1,30

2,15

3,10

5,6

The greatest common factor between these is 5. Therefore, we divide 25+30 by 5 and put the 5 on the outside.

5(5+6).

This has the same value but it is just written differently.

Have a wonderful day! :D
