Answer:
132 ft²
Step-by-step explanation:
The shape is composed of a rectangle and a triangle.
Area of the shape = area of rectangle + area of triangle
Area of rectangle = L*W
L = 12 ft
W = 8 ft
Area of rectangle = 12*8 = 96 ft²
Area of triangle = ½bh
b = 8 ft
h = 21 - 12 = 9 ft
Area of triangle = ½(8*9) = 36 ft²
Area of the shape = 96 + 36 = 132 ft²
We are given that the
operation of all circuits is independent with each other, therefore we can use
the multiplication rule for independent events, which states that P (intersection
of A and B) = P(A) * P(B). In this case, we want the intersection of circuit 1 to
be working with the intersection of circuit 2 on and on until circuit 40. That
is, we want every circuit to work with each other. The given probability that
circuit 1 works is .99. The probability that circuit 2 works is still .99 since
this is independent events. And we see that the probability for each of the 40
circuit to work is .99. <span>
So P (intersection of 1 through 40) = .99 * .99 *
.99.....*.99 = (.99)^40 = .6689717586</span>
Answer:
<span>There is a 0.67 probability
(or 67%) that the product will work.</span>

Answer:
6.4 is the correct answer
Supplementary Angles = 180
180 - 32 = 148
The supplementary angle of 32 would be 148.
