Answer:
Step-by-step explanation:
Given the total cost of the building expressed as;
C = 4550F + 37.5
C is the total cost
F is the length of the fence
Given
C = $352.50
Required
The length of the fence F
Substitute into the formula;
C = 4550F + 37.5
$352.50 = 4550F + 37.5
4550F = 352.50 - 36.5
4550F = 316
F = 316/4550
F = 0.0695 feet
hence 0.0695 feet of fence will cost $352.50
The property x^axb makes it x^a+b so x^5x-2 ,
Therefore x^-10 is final

Answer:
Expected number of books = 1.0
Step-by-step explanation:
Expected number of books, E(x) = ∑xp(x)
∑ = Summation
x = books
p(x) = probability of purchasing a book
E(x) = (0*0.4) + (1*0.2) + (2*0.4)
E(x) = 0 + 0.2 + 0.8 = 1.0
Answer:
400
Step-by-step explanation:
20/100 = 80/x
Cross multiply and divide
100 X 80 = 8000 / 20 = 400
