Answer:
The scaled surface area of a square pyramid to the original surface area.
The scaled area of a triangle to the original area.
Step-by-step explanation:
Suppose that we have a cube with sidelength M.
if we rescale this measure with a scale factor 8, we get 8*M
Now, if previously the area of one side was of order M^2, with the rescaled measure the area will be something like (8*M)^2 = 64*M^2
This means that the ratio of the surfaces/areas will be 64.
(and will be the same for a pyramid, a rectangle, etc)
Then the correct options will be the ones related to surfaces, that are:
The scaled surface area of a square pyramid to the original surface area.
The scaled area of a triangle to the original area.
<span>1. Ways to choose Lar, 1F, 2 other M} = 1 C(7,1) C(4,2) = 42
Ways to choose {Lar, 2F, 1 other M}; = 1 C(7,2) C(4,1)= 84
Ways to choose {Lar, 3F, 0 other M} = 1 C(7,3) C(4,0) = 35
Ways to choose 4 from 12 is C(12,4) = 495
P(L and at least 1F) = [42 + 84 +35] / 495 = 161/495 =.325 approx</span><span>
2. P(Larry and at least 1 F)
P(at least 1F) = 1 - P(0F) = 1 -{ [C(7,0)C(5,4)] } / C(12,4) = 5/495 = 490/495 = 98/99 = .99.
Ways to choose Larry = 1 C(1,1) = 1
P(Larry and at least 1 F) = 1(98/99) = 98/99 = .99 approx</span>
I can give you one form, maybe changing 0.924 into a fraction like this: 924/1000
