Step-by-step explanation:
Given
Let:
Strawberry
Grape
The given parameter can be represented as:

Required
The question is incomplete as what is required is not stated.
Possible questions could be to determine the number of strawberries given a certain number of grapes, and vice versa
Take for instance
Calculate the number of grapes when there are 20 strawberries
We have:

This becomes

Express as fraction

Make G the subject



<em>i.e. 50 grapes</em>
<em>Apply the same method given a certain number of grapes</em>
This is impossible to answer without knowing what the sets A and B contain (and what ξ even refers to - universal set?).
However, we have
(A U B)' = A' ∩ B'
so that
(A ∩ B) U (A U B)' = (A ∩ B) U (A' ∩ B') = (A U A') ∩ (B U B')
If ξ is indeed the universal set, then both A U A' = ξ and B U B' = ξ, so we end up with ξ ∩ ξ = ξ.
Fh. = 40h + 120, fh. = $200
200 = 40h + 120
200 - 120 = 40h
80 = 40h
80/40 = h
2 = h
h = 2 hours.
48/75 = 0,64 and they want a percentage so 64%
The slope of the line is -4
