Answer:
(x-7)² + (y+1)² = 4² or (x-7)² + (y+1)² =16
Step-by-step explanation:
1) coordinates of the center
x0=(x1+x2)/2=(7+7)/2=7
y0=(y1+y1)/2=(3-5)/2 = -1
(7, -1) - coordinates of the center
2) radius of the circle
length of the diameter =√((x2-x1)²+(y2-y1)²)=√((7-7)²+(-5-3)²)=√(8)²= 8
r = length of the radius = length of the diameter / 2 = 8/2 = 4
3) the equation of the circle
(x-x0)² + (y-y0)²= r²
(x-7)² + (y+1)² = 4²=16
<span>3 coins are tossed and 3 six sided dice are rolled.what is the probability of getting 3 heads and an even number on a dice
-----
P(3 heads) = 1/8
P(even #) = 1/2
======
P(3 heads AND even #) = (1/8)(1/2) = 1/16

Answer:
Dark matter is just matter whose particles do not absorb reflect or emit light and can't be seen directly. We know of its existence because of its effects on objects that we c a n see. It's density formula is 2.241×10⁻²⁷ kg/m³
Step-by-step explanation:
Im not so sure about Q2 but 3 and 4 are correct for sure.
