<h3>
Answer: D) 63</h3>
======================================================
Work Shown:
The notation B U C means "set B or set C". The U refers to set union. A set union is where you combine two sets and toss out any duplicates. In terms of a venn diagram, we will add up any number that is either in set B, set C, or both sets at the same time.
So we just add up the numbers: {6, 19, 5, 8, 3, 22} to get
6+19+5+8+3+22 = 63
There are 63 items in either set B, set C or both.
-----------------
Alternative route:
n(B) = number of items in set B
n(B) = 6+19+5+8 ... add up the numbers in circle B
n(B) = 38
n(C) = number of items in set C
n(C) = 3+5+8+22
n(C) = 38
n(B and C) = number of items in both set B and set C
n(B and C) = 5+8
n(B and C) = 13
n(B U C) = n(B) + n(C) - n(B and C)
n(B U C) = 38 + 38 - 13
n(B U C) = 63

Answer:
[130-5(13)] (13) = $845 max revenue.
Step-by-step explanation:
If the number of books sold = 130-5p then revenue will be (130-5p)p = -5p^2+130p
the maximum can be found by graphing or by the fact that the max will be -b/2a = -130/-10 = 13 dollars/book
[130-5(13)] (13) = $845 max revenue.
Answer:
No
Step-by-step explanation:
17/10 is not proportional to 12/5. Proportional relationships are relationships between two variables where their ratios are equivalent. 17/10 as a ratio is 17:10 and 12/5 as a ratio would be 12:5. A proportional relationship for 12/5 would be 24/10.
Hope this helps :)
