P( both allergic) = 0.17*0.17 = 0.0289
P(at least one is allergic) = 1 - P(neither are allergic) = 1 - 0.83^2 = 0.311
draw a perpendicular line from the directrix passing through the focus, this will be the line of symmetry.
The vertex(h, k) will be located on the line half way between the focus and directrix.
The distance from the focus to the vertex is called the focal length, call it a. The then equation is
(x - h)^2 = 4a(y - k)
the equation can be manipulated to
y = 1/4a(x - h)^2 + k
hope it helps
Answer:
The equation that can be used to find the missing number is 96 - 12n = 3 + n
Step-by-step explanation:
The difference of 8 less a number n
This is 8 - n
Multiplied by twelve
This is:
12(8 - n) = 96 - 12n
Is equal to 3 more than the number.
96 - 12n = 3 + n
The equation that can be used to find the missing number is 96 - 12n = 3 + n
(5*3)(2*3)=(15)(6)=90
7*3=21
21*3=63
