there are 30 students in a class. of those, 15 take history, 18 take geography, and 5 take neither of
these subjects. how many students
take both subjects?
.
Answer:
n(U)=30
n(H)=15
n(G)=18
n(H ∪ G)'=5
n(H ∪ G)=n(U)-n(H ∪ G)'
=30-5=25
So ,n(H ∩ G)=n(H)+n(G)-n(H ∪ G)
=15+18-25=8
Therefore, 8 students take both subjects.
A set is a mathematical model for a collection of diverse things. The total number of students who who take both History and Geography is 8.
What is a set?A set is a mathematical model for a collection of diverse things; it comprises elements or members, which can be any mathematical object: numbers, symbols, points in space, lines, other geometrical structures, variables, or even other sets.
Given that there are 30 students in a class. of those, 15 take history, 18 take geography, and 5 take neither of these subjects. Therefore, we can write the following values,
Total students, n(S)=30Students who take History, n(H)=15Students who take Geography, n(G)=18Students who take neither of the subject, n(H' ∪ G') =5Now, the number of students who take at least one of the two subject can be written as,
Students who choose at least one subject
= Total students - Students who take neither of the subject
n(H ∪ G) = n(U) - n(H ∪ G)'
n(H ∪ G) = 30 - 5
=25
Further, the total number of students who who take both the subjects can be written as,
Students who take both the subjects = Students who take History + Students who take Geography - Students who choose at least one subject
n(H ∩ G) = n(H) + n(G) - n(H ∪ G)
n(H ∩ G) = 15 + 18 - 25
n(H ∩ G) = 8
Hence, the total number of students who who take both History and Geography is 8.

Which statements about this system of equations are true? Check all that apply. Negative x + 6 y = 16. 8 x minus 6 y = negative 2. The x-variable will be eliminated when adding the system of equations. The y-variable will be eliminated when adding the system of equations. The sum of the system of equations is Negative 8 x = 14. X = 2 y = 3 There is only one solution to the system of equations.
Answer:
The y-variable will be eliminated when adding the system of equations.
There is only one solution to the system of equations.
Step-by-step explanation:
-x + 6y = 16 (1)
8x - 6y = -2 (2)
Add the equations to eliminate y
-x + 8x = 16 +(-2)
7x = 16 -2
7x = 14
x = 14/7
x = 2
Substitute x = 2 into (1)
-x + 6y = 16 (1)
-2 + 6y = 16
6y = 16 + 2
6y = 18
y = 18/6
y = 3
(x, y) = (2, 3)

Part A Anna took a taxi home from the airport. The taxi fare was \$ 2.1$2.1 per mile, she gave the driver a tip of \$ 5$5, and Anna paid a total of \$ 49.10$49.10. Write an equation to determine the distance in miles \left(x\right)(x) between the airport and Anna's home. Answer: Part B Find the distance between the airport and Anna's home. Answer: miles.
Answer:
44.10 = 2.1x
x = 21 miles
Step-by-step explanation:
Cost per mile = $2.1
Driver tip = $5
Total amount paid = $49.10
Let
x = number of miles
Write an equation to determine the distance in miles \left(x\right)(x) between the airport and Anna's home.
Total cost of miles = Total amount paid - Driver tip
= $49.10 - $5
= $44.10
Equation to determine distance in miles
Total cost of miles = cost per mile * number of miles
44.10 = 2.1x
Find the distance between the airport and Anna's home
44.10 = 2.1x
Divide both sides by 2.1
44.10 / 2.1 = 2.1x / 2.1
21 = x
x = 21 miles

What is the convergent of a series?
A series is convergent if the series of its partial sums approaches a limit; that really is, when the values are added one after the other in the order defined by the numbers, the partial sums get closer and closer to a certain number.
The sequence can be defined as the systematic way of representing the data that follows a certain rule of arithmetic.
It is given that:
The sequence:
3/4, 4/5, 5/6, 6/7, . . .
AS we know, the convergent sequence occurs when, as n approaches infinity, you arrive at a final and constant term through a number of terms.
Divergent sequences are those in which the terms never stabilize; instead, they constantly increase or decrease as n approaches infinity, approaching either infinity or -infinity.
The nth term of the sequence
a(n) = 2+n/3+n
Applying divergence test:
The sequence diverges
Thus, the sequence 3/4, 4/5, 5/6, 6/7, . . . is diverges option (A) The sequence diverges is correct.

Answer:
Step-by-step explanation:
Volume of a pyramid = [tex]\frac{1}{3}(\text{Area of the rectangular base})(\text{Height})[/tex]
Area of the rectangular base = Length × Width
= 8 × 6
= 48 mm²
Volume of the pyramid = 192 mm³
192 = [tex]\frac{1}{3}(48)h[/tex]
h = [tex]\frac{192}{16}[/tex]
h = 12 mm
Therefore, all the pyramids having height less than 12 mm will be fitted inside the given pyramid.

Use a calculator to find the value of these data. Round the value to three
decimal places.
A-0.953
B. -1.909
C. 0.909
D. 0.953
The value of coefficient of correlation coefficient is -0.953 which is a negative correlation between x and y option (A) is correct.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
We have given data in the table.
As we know, the formula for the correlation is given by:
[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]
After plugging the value, we will get the value of r:
r = -0.953
Thus, the value of coefficient of correlation coefficient is -0.953 which is a negative correlation between x and y option (A) is correct.
