Find x so the distance between (x, 2) and (1, 4) is square root 13

distance = sqrt( (x1-x2)^2+(y1-y2)^2)

sqrt(13) = sqrt ((x-1)^2+(4-2)^2)

square each side

13 =  ((x-1)^2+(4-2)^2)

13 = ((x-1)^2+(2)^2)

13 = (x-1)^2+4

subtract 4 from each side

9 = (x-1)^2

take the square root of each side  (remember plus and minus)

sqrt(9) - sqrt((x-1)^2)

3 = x-1                                 -3 = x-1

add 1 to each side

4 =x                                     -2 =x

Answer x= -2, 4

The formula of a distance between two points:

We have the points (x, 2) and (1,4) and the distance d = √13.

Substitute:

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

pretty sure 750 each month!
