Answer: 0.29 (29%)
Step-by-step explanation:
women who gave birth at a certain hospital last year:
over 30 years old - 0.48
unmarried - 0.46
over 30 or unmarried (or both) - 0.65
what is the probability that a woman who gave birth at the hospital was both unmarried and over 30 ?
We know that
P(A and B) = P(A) + P(B) - P(A or B)
P(+30 and unmarried) = P(+30) + P(unmarried) - P(+30 or unmarried)
P(+30 and unmarried) = 0.48 + 0.46 - 0.65 = 0.29
Standard form of a circle is (x-h)²+(y-k)²=r², (h, k) being the center, r the radius.
In this case, (x-h)²+(y-k)²=16
the circles pass through (1,1), that is x=1, y=1
Plug x=1,y=1 in the equation: (1-h)²+(1-k)²=16
if h=1, k is either -3 or 5
so the equation is (x-1)²+(y+3)²=16 or (x-1)²+(y-5)²=16
You can also set k=1, h=-3 or 5
Note: there are many other possibilities.
If you solve a linear equation in one variable, "x=0" tells you that substituting 0 for x makes the equation true.
