For the mean, add together all of the numbers together (let's call the total x) and count how many numbers there are. (let's call this number y). divide x by y, and that is your mean. for the median, put all the numbers in order, and the median is the number in the middle. if there are two numbers in the middle, add them together and divide them by 2.

Consider this system of equation. Which shows the second equation written in slope-intercept form?y = 3x - 210(x+3/5)=2yA) y=5x+

SashulF [63]

we have that

y = 3x - 2

10(x+3/5)=2y------> the second equation----->divide by 2 both sides

5(x+3/5)=y-----> y=5x+3

y=5x+3------> second equation written in slope-intercept form

so

case A) y=5x+3/10-----> is not equal to y=5x+3

case B) y=5x+3--->is equal to y=5x+3---------> is the answer

case C) y=1/5x+3/25-------> is not equal to y=5x+3

case D) y=1/2x+6-----> is not equal to y=5x+3

therefore

the answer is the option

B) y=5x+3

If (-1,4) and (3,-2) are end points of diameter of the circle, then the equation of the circle is

Volgvan

Answer:

If you've more doubts you can ask :)

Step-by-step explanation:

If the centre of a circle is (a, b) and radius r, then the equation of the circle is :

$(x - x)^2 + (y-b)^2 = r^2$

<em><u>First we will find the centre, (a , b): </u></em>

<em><u /></em> $a = \frac{3+(-1)}{2} = \frac{2}{2} = 1\\\\b = \frac{-2 + 4}{2} = \frac{2}{2} = 1$ <em><u /></em>

<em><u>Find radius:</u></em>

$Radius, r = \frac{Diameter}{2}$

Diameter is the distance between (-1, 4) and (3, -2)

$diameter = \sqrt{(x_2 - x_1)^2 +(y_2-y_1)^2} \\\\$

$= \sqrt{(3-(-1)^2 + (-2-4)^2} \\\\=\sqrt{16 + 36}\\\\=\sqrt{52}\\\\=\sqrt{4 \times 13}\\\\=2\sqrt{13} \ units$

Therefore , $r = \frac{2 \times \sqrt{13} }{2} = \sqrt{13} \ units$

<em><u>Equation of the circle is : </u></em>

$(x - 1)^2 +(y-1)^2 = 13$ <em><u></u></em>
