Given
Required
This is calculated using
This gives:
--- approximated
Solving (b):
Given
i)
Required
This is calculated as:
--- Complement rule

So:

ii)

This is calculated as:



iii)

This is calculated as:


iv)

This is calculated as:


Solving (c):

This is calculated as:




Express as percentage

The calculated probability (1.18%) is way less than the advocate's claim.
Hence, we do not believe the claim.
c(x) = 4x - 2
d(x) = x^2 + 5x
4x - 2(x^2 + 5x)
<em><u>Using FOIL, distribute each term appropriately. </u></em>
4x^3 + 20x^2 - 2x^2 - 10x
<em><u>Combine like terms.</u></em>
4x^3 + 18x^2 - 10x is the simplified polynomials achieved when c(x) and d(x) are multiplied.
Answer:
Jay did.
Step-by-step explanation:
Jay ate 2/3 of a pizza, while Darrell ate 2/4
2/3 is greater, like 6/9, but, 2/4 is only half, like 4.5/9
Answer:
The slope is -1/2 or -0.5
