<span>Given the two end of the diameter of the circle, we are able to compute the center of the circle as 0.5*[(-1,3)+(7,-7)]=(3,-2). The radius of the circle is 0.5*sqrt[(-1-7)^2+(3+7)^2]=sqrt(41). Therefore the equation of the circle is (x-3)^2+(y+2)^2=41.</span>
Answer:
x+y=4+8=12
$12 for one of each
or if you mean indivually (the wording confused me)
$4 for child, $8 for adult
Step-by-step explanation:
x=adult
y=child
2x+10y=56
4x+5y=52
iin order to be able to subtract values and find x and y im going to multiply 4x+5y=52 by two and get 8x+10y=104
8x+10y=104
-2x+10y=56
6x=48 divide each side by 6
x=8
plug 8 back into an equation to find cost of y
2(8)+10y=56
-16 -16
10y=40
y=4
Answer:![\frac{5}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B6%7D)
Step-by-step explanation:
breaststroke=50
backstroke=60
ratio=breaststroke:backstroke
=50:60=5:6
I think it's D. That question is a bit weird so I can't explain it to you but my educated guess would be D. I'm sorry.
Answer:
But does not touch the horizontal axis.
Step-by-step explanation:
The curve of a normal distribution extends indefinitely at the tails but does not " touch the horizontal axis."
The reason for this is that the tails of the curve suggest that a variable can take on any theoretically reasonable value, although the probability of such occurrence is considerably low.
Generally, a normal distribution curve is considered to be asymptotic to the horizontal axis.
