hram777 [196]
There are 9 long distance male runners and 5 long distance female runners. This makes a total of 9+5 = 14 long distance runners.

Out of this total of 14 long distance runners, there are 9 males. So the probability as a fraction is 9/14

If you need the answer in decimal form, then use a calculator to get 9/14 = 0.642857 which is approximate.

Write the equation of the sphere in standard form. x2 + y2 + z2 + 8x − 6y + 4z + 20 = 0
Nuetrik [128]

Answer:

(x+4)^2 + (y-3)^2 + (z+2)^2 - 3^2 = 0


Step-by-step explanation:

You have to find a, b, c, r so that the polynomial expands to match the given equation.

(x-a)^2 + (y-b)^2 + (z-c)^2 - r^2 =\\x^2-2ax+a^2+\\y^2-2by+b^2+\\z^2-2cz+c^2-r^2 =\\ x^2 + y^2 + z^2 + 8x - 6y + 4z + 20

(a^2+b^2+c^2-r^2-20)+\\x(-8-2a)+y(6-2b)+z(-4-2c)=0

-8-2a=0, 6-2b=0, -4-2c=0\\a=-4, b=3, c=-2

(-4)^2+3^2+(-2)^2-r^2-20 = 0

16+9+4-20=r^2

r^2=9

r=3

(x+4)^2 + (y-3)^2 + (z+2)^2 - 3^2 = 0
