Answer:
39 read all three news papers,72 Exactly two Papers & 52 reads Guardian Alone
Step-by-step explanation:
We have given, A survey of 290 newspaper readers.
Who read the Daily times A=181
Who read the Guardian times B=142
Who read the punch C=117
Who read Daily Times and the Guardian A\cap B= 75
Who read Daily Times and the punch A\cap C=60
Who read Guardian and punch B\cap C=54
To find :
How many readers read All three papers, Exactly two of the papers The Guardian alone?
Solution :
Readers read all three papers is
Total survey is given by,
Total =
290 =
290 =
290-251=
So, number of readers who read all three papers is 39.
Exactly two of the papers = 36 + 21 + 15 = 72
Guardian Alone = 52
Answer:
The width of the area model is equal to
Step-by-step explanation:
<u><em>The complete question is</em></u>
Todor was trying to factor 10x^2-5x+15 he found the greatest common factor of these terms was 5 what is the width
we know that
The area of a rectangular model is given by the formula
----> equation A
where
L is the length
W is the width
we have
Factor the expression
substitute the value of the Area in the equation A
In this problem
The greatest common factor of these terms is the length (L=5 units)
so
we can say that the width is equal to (2x^2-x+3)
therefore
The width of the area model is equal to
