Step-by-step explanation:

1. We aren't worried about the area of the base, so the area is the area of the 4 triangles.  Each triangle has an area of half the base times the height.

A = 4 (½ bh)

A = 2 bh

Given b = 6 and h (the height of the triangle, not the pyramid) = 5:

A = 2 (6) (5)

A = 60 ft²

2. This time, we want to include the area of the rectangular base, so:

A = b₁b₂ + 2 (½ b₁h₁) + 2 (½ b₂h₂)

A = b₁b₂ + b₁h₁ + b₂h₂

Given b₁ = 78 m, b₂ = 50 m, h₁ = 52 m, and h₂ = 60 m:

A = (78) (50) + (78) (52) + (50) (60)

A = 10,956 m²

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
