Find the midpoint and distance between each pair of points, with easy explanation and work !! will give brainliest.
rewona [7]
If we have 2 coordinates say: (x1,y1) and (x2,y2)

Then the formula for the midpoint is:

((x1+x2)/2,(y1+y2)/2)

And the formula for the distance is:

Sqrt((x2-x1)^2+(y2-y1)^2)

So here we have (-1,-4) and (-7,4)

The midpoint is:

((-1+-7)/2,(-4+4)/2) = (-8/2,0/2) = (-4,0)

The distance is:

Sqrt((-7- -1)^2+(4- -4)^2)
= sqrt((-6^2)+(8^2))
=sqrt(36+64)
=sqrt(100)

In a survey of 248 people, 156 are married, 70 are self-employed, and 25 percent of those who are married are self-employed. If
MatroZZZ [7]

Answer:

The probability of selecting a  person which is  self-employed but not married equals 1/8.

Step-by-step explanation:

Here, the given survey says:

Total number of people surveyed = 248

Number of people married = 156

The number of people are self employed = 70

Now, 25% of people who are married are SELF EMPLOYED.

Now, calculating 25% of 156 , we get:

\frac{25}{100} \times 156 = 39

⇒ out of total 156 married people, 39 are self employed.

So, number of  self employed people but  not married

= Self employed people - Self employed people PLUS  married

=  70  -  39   =  31.

So, the probability that the person selected will be self-employed but not married = \frac{\textrm{The total number of people self-employed but not married}}{\textrm{Total Number of people}} =  \frac{31}{248}  = \frac{1}{8}

Hence The probability of selecting a  person which is  self-employed but not married equals 1/8.
