Answer:
We can first determine it is not A or C, because these flatly do not equal the expression above.
I believe is it D, because of the commutative property.
The associative property of addition states that you can group the addends in different ways without changing the outcome. While the commutative property of addition states that you can reorder the addends without changing the outcome.
In this case, we are rearranging the addends, not groups of them.

Let U = {English, French, History, Math, Physics, Chemistry, Psychology, Drama}, A = {Math, History, Chemistry, English}, B = {Psychology, Drama, French, Chemistry, English}, and C = {Physics, History, French}. Find the following. n(B u C)
Answers
We are provided with ;
[tex]{\sf{U=\{English,\: French,\: History,\: Math,\: Physics,\: Chemistry,\: Psychology,\: Drama\}}}[/tex] [tex]{\sf{A=\{Math,\: History,\: Chemistry,\: English\}}}[/tex] [tex]{\sf{B=\{Psychology,\: Drama,\: French,\: Chemistry,\: English\}}}[/tex] [tex]{\sf{C=\{Physics,\: History,\: French\}}}[/tex]And we need no find [tex]{\bf n(B\cup C)}[/tex] . At first Let me tell you that here [tex]{\sf (B\cup C)}[/tex] represents the union of the set B and C.And [tex]{\sf n(B\cup C)}[/tex] represents the cardinal no. of the respective set or no. of elements present in the respective set.So let's find the set [tex]{\sf (B\cup C)}[/tex] first
[tex]{:\implies \quad \sf B\cup C=\{Physics,\: Drama,\: French,\: Chemistry,\: English,\: Psychology,\:History\}}[/tex]
[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{n(B\cup C)=7}}}[/tex]
Alternative Method :-As we know that ;
[tex]{\boxed{\bf n(A\cup B)=n(A)+n(B)-n(A\cap B)}}[/tex]Where [tex]{\sf (A\cap B)}[/tex] is the Intersection of A and B or the set of common elements of A and B. So now by same concept , now finding the intersection of B and C :-
[tex]{:\implies \quad \sf B\cap C=\{French\}}[/tex]
So , [tex]{\sf n(B\cap C)=1}[/tex] . Now , putting the values in the formula;
[tex]{:\implies \quad \sf n(B\cup C)=n(B)+n(C)-n(B\cap C)}[/tex]
[tex]{:\implies \quad \sf n(B\cup C)=5+3-1}[/tex]
[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{n(B\cup C)=7}}}[/tex]

please hurry .The side of Mr. Miller’s barn has a length of 27 feet and an area of 656.1 square feet. How wide is the side of Mr. Miller’s barn?
Answers
Answer:
24.3
Step-by-step explanation:
area of a rectangle =length*width
if we know at least the 2 quantities already
total area = 656.1
and one of the sides = 27
we have to divide the are by one of the sides to get the remaining side
width = area/length
656.1 divided by 27 equals 24.3

The population of a school is 800 and is increasing at a of 2% per year , 6 years
Answers
My answer is assuming that you want the final population after the 6 years since you did not tell me the question.
If it increases 2% a year then it can be expressed in a exponential function.
Result=800*(1+0.02)^6
Result≈900.93
And since there cannot be part of a student, we round down and get the answer of 900 students after the sixth year.

4. Earl still hates to wash dishes and take out the trash. He finds his own weighted coin, one that
will randomly land on heads 30% of time. He will flip a coin once for each chore and will
perform the chore if the coin lands on heads.
A.) what is the probability that Earl will get out of the doing both chores?
B.) what is the probability that Earl will have to take out the trash but will not need to wash dishes?
Answers
Answer:
49%
21%
Step-by-step explanation:
Hello!
This is a probability question.
There is a 30% chance they need to do the chore and a 70% chance they don't for every coin toss.
Let's put this into fractions. 30% = 3/10. 70% = 7/10.
Now, to calculate a compound probability, we need to multiply the probability of each of the outcomes of the events.
A)
We have two events here. One where he doesn't do the chore and the other where he also doesn't do the chore.
Both events on their own have a 70% chance of happening or 7/10. So we multiply both the numbers together to find the compound probability. 7/10 * 7/10 = 49/100. 49/100 = 49%.
B)
We follow the same guidelines here. The probability of not doing the chore is 70% or 7/10, and the probability of doing the chore is 30%, or 3/10.
Now you need to multiply both probabilities. 7/10 * 3/10 = 21/100. 21/100 = 21%.
Let me know if you have any questions.
