If the endpoints of the diameter of a circle are (−10, −8) and (−6, −2), what is the standard form equation of the circle? A) (x
kolbaska11 [484]
Selections B and D both appear to be appropriate.
  B) (x+8)² + (y+5)² = 13
  D) (x+8)² + (y+5)² = 13

_____
The center is at the midpoint of the diameter, ((-10-6)/2, (-8-2)/2) = (-8, -5). For center (h, k) and radius r, the equation is
  (x -h)² +(y -k)² = r²
  (x -(-8))² +(y -(-5))² = (√13)²
  (x+8)² + (y+5)² = 13

Kyle asked a random group of students what their favorite sport was. The results are below. Boys Girls Basketball 10 8 Football
Ronch [10]

Answer:

The probability that Kyle will pick a girl who likes football is 12.5%.

Step-by-step explanation:

The data provided is as follows:

                         Boys        Girls       Total

Basketball          10             8             18

 Football           25             7             32

  Soccer             9             19             28

 Baseball           18            22            40

   Total               62           56            118

Compute the probability that Kyle will pick a girl who likes football as follows:

P(F|G)=\frac{n(G\cap F)}{n(G)}

            =\frac{7}{56}\\\\=0.125\\\\=12.5\%

Thus, the probability that Kyle will pick a girl who likes football is 12.5%.

How do you find the x and y intercepts of x^2+x-2/x^2-3x-4?
melomori [17]
First equal the equation to f(x) or y 

f(x)= (x²+x-2)÷(x²-3x-4) 

To find y-intercept, x coordinates have to be 0 

f(0)=(0²+0-2)÷(0²-3(0)-4) 
f(0)=-2/-4
f(0)=1/2 (y-intercept)

To find x-intercept, make y=0 

0=(x²+x-2)÷(x²-3x-4) 
0((x²-3x-4)=(x²+x-2) 
0=x²+x-2 
0=(x-1)(x+2) 
x-1

x-1=0 
x=1 

x+2=0 
x=-2 

The x-intercepts would be 1, -2 

Hope I helped :)
