What is the Venn diagram?A Venn diagram is a diagram that helps us visualize the logical relationship between sets and their elements and helps us solve examples based on these sets. A Venn diagram typically uses intersecting and non-intersecting circles (although other closed figures like squares may be used) to denote the relationship between sets.
Let Math=M, Science=S and English=E
n(M)+n(S)+n(E)=1/2 (n(M∩S)+n(S∩E)+n(E∩M)
Let the number of students who study only one subject be x.
Let the number of students who study only two subjects be x/2.
n(M∩S∩E)=20
n(M∩S)+n(S∩E)+n(E∩M)=80
∪=x/2+80
∪=x+ x/2+20
Now, x/2+80 = x+ x/2+20
⇒ x=60
So, ∪=x/2+80 =110
Therefore, the total number of students in the survey is 110 students.

For 15 points.Explain, in your own words, the steps necessary to solve a system of equations
using the substitution method.
First, what is an equation?
➳ A mathematical statement which shows that two algebraic expressions are equal is called and equation.
Or, LHS = RHS
Example:- 3x - 5 = x + 8
An equation is said to be a linear equation if it contains only one variable (literal) with highest power 1.
_______________________
Solving an equation:-
To solve the equation x + 5 = 7 means to find the value of an unknown algebraic quantity used in the equation.
Example:-
To solve the equation x + 5 = 7 means to find the value of x.To solve the equation 3y + 2 = 9 means to find the value of y.To solve the equation [tex]\sf \dfrac{2a}{3} + 4 = 10[/tex] means to find the value of a ⠀⠀⠀⠀⠀⠀and so on!⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
★ Rules for solving an equation by the substitution method:-
Rule ❶
If x = 2, the value of the expression 3x + 2 = 3 × 2 + 2 = 6 + 2 = 8
Rule ❷
If x = 0, the value of the expression 3x + 2 = 3 × 0 + 2 = 0 + 2 = 2
Rule ❸
If x = -2, the value of the expression 3x + 2 = 3 × -2 + 2 = -6 + 2 = -4
Now consider the algebraic expression 5x - 2y
This expression consists of variables x and y.
Now if :-
x = 3 and y = 2, 5x - 2y = 5 × 3 2 × 2 = 15 - 4 = 11x = 8 and y = 5, 5x - 2y = 5 × 8 - 2 × 5 = 40 - 10 = 30⠀⠀⠀⠀⠀⠀⠀⠀
The process of finding the value of an algebraic expression by substituting the given value of its variable is called substitution.⠀⠀

Callie posted a cute cat video on a popular website. On the first day after she posted the video, the video had 5 views. On the second day, it had 15 views. On the third day, it had 45 views, and on the fourth day, it had 135 views.
A. How many views would you expect the video to have after 5 days? Explain how you found your answer.
B. Which type of reasoning did you use to solve this problem, deductive or inductive? (2 points)
Answer:
(A) 5th day: 405 views
(B) inductive
Step-by-step explanation:
Each day the views get multiplied by 3.
Answer:
A. I would expect the video to have 405 views after day 5. There is a pattern of the number being multiplied by 3.
B. Deductive reasoning
Step-by-step explanation:
(This is really going to explain BOTH questions at the same time)
Looking that the problem, the number of views keep going up. There is a multiplier behind this, we just don't know WHAT multiplier it would be. To find that out, divide 1 value by the one before it. I'll do 135 divided by 45 as an example. That would equal three. Now we know the multiplier is 3. So, now we need to multiply 135 by 3 to get 405 views after five days.
(This is really summarizing B, whilst answering A.)

An oblique cylinder has a radius of 16 meters and a volume of 5,120(pi) cubic meters. Use Cavalieri’s Principle to solve for the height of the solid.
20 meters
25 meters
50 meters
250 meters
Answer: 20 meters
Step-by-step explanation:
We are told that an oblique cylinder has a radius of 16 meters and a volume of 5,120 pi cubic meters. We will use volume of oblique cylinder to find the height of our given cylinder. volume of a oblique cylinder= πr²hUpon substituting our given values in above formula we will get,5,120π m³ = π ( 16 m² × h )
5,120π m³ = π × 256 m² × h
Let us divide both sides of our equation by 100 pi.Therefore, height of our given oblique cylinder is 20 meters.

If you randomly select a card from a well-shuffled standard deck of 52 cards, determine the probability that the card you
select is a 6.
a) Write your answer as a reduced fraction.
b) Write your answer as a decimal, rounded to the nearest thousandth.
c) Write your answer as a percent. Round to the nearest tenth of a percent as needed.
Answer:
a. 1/13
b. 0.077
c. 7.7
Step-by-step explanation:
a. there are 4 of the 6 in a deck of cards so the probability of taking this cards from the deck of 52 cards is 4/52. Given you 1/13.
Probability is the chance of an event to occur from a total number of outcomes.
The answer in the reduced fraction is 1/13
The answer in decimal is 0.077
The answer as a percentage is 7.7 %
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
Number of cards = 52
The number of cards randomly selected = 1
The number of cards that is 6 in a deck of 52 cards:
= 4
i.e
6 of spade
6 of diamond
6 of hearts
6 of club
Now,
The probability that a randomly selected card from a deck of
52 cards is 6:
= Number of cards that is 6 / Total number of cards
= 4 /52
The answer in the reduced fraction of 4/52 is 1/13
The answer in decimal:
= 4/52
= 0.0769
Rounding to its nearest thousandth.
= 0.077
The answer as a percent:
= 4/52 x 100
= 0.0769 x 100
= 7.69 %
Rounding to the nearest tenth.
= 7.7 %
Thus,
The answer in the reduced fraction is 1/13
The answer in decimal is 0.077
The answer as a percentage is 7.7 %

Answer:
b
Step-by-step explanation:
The slope of b is 5.5 whereas the slope for the other three graphs are 5, so B is different from the rest.
A. (4, 0.8), so by rise over run, the slope is 4/0.8=5.
B. (55, 10), so 55/10=5.5.
C. (20, 4), so 20/4=5.
D. (50, 10), so 50/10=5.
Since B is the only graph with a slope of 5.5 and the other graphs have a slope of 5, the answer is B.

Aiden earned $50 in interest in six
months. If his savings account has a
rate of 5%, how much did Aiden
start with in his account?
9514 1404 393
Answer:
$2000
Step-by-step explanation:
The amount of interest is given by the formula ...
I = Prt
where P is the principal invested, r is the annual rate, and t is the number of years. Here, we want to find P when I = 50, r = 0.05, and t = 1/2.
50 = P(0.05)(1/2)
P = 50/(0.05·1/2) = 2000
Alden started with $2000 in his account.
