Class of 40 students, 20 took Mathematics, 18 took Statistics, 16 took English, 7 took Mathematics and Statistics, 7 took Mathematics and English, 9 took Statistics and English, 3 took all the three.How many students arn't taking any courses?
Answer:
6
Step-by-step explanation:
Typically these kinds of problems are solved using Venn Diagram.
Let’s solve it differently.
Here, we add the individual subject students and subtract the dual subject students and then add the triple subject students that would give us the count of all the students. If that’s more than number of students then there’s something wrong with the given data. If that’s exactly equal to number of students then all the students have taken some course(s) or the other. If that’s less than number of students then subtracting this from number of students would give us the count of students having not taken any course(s).
Thus, the count of students having taken some courses or the other is:
20+18+16–7–7–9+3 = 57–23
= 34
Subtracting it from 40 gives us 6, which is the count of students not taking any course(s).

Solve the following question:
Answer:
x = 2, x = 8
Step-by-step explanation:
reminder that f'(x) = [tex]m_{tangent}[/tex]
Differentiate f(x) term by term using the power rule
[tex]\frac{d}{dx}[/tex] (a[tex]x^{n}[/tex] ) = na[tex]x^{n-1}[/tex]
f(x) = [tex]\frac{1}{3}[/tex] x³ - 5x² + 2x + 10
f'(x) = x² - 10x + 2
Equating f'(x) to - 14
x² - 10x + 2 = - 14 ( add 14 to both sides )
x² - 10x + 16 = 0 ← in standard form
(x - 2)(x - 8) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2
x - 8 = 0 ⇒ x = 8
[tex]1+2x=4x+9[/tex]
Answer:
x= -4
Step-by-step explanation:
=> 1+2x= 4x+9
=> 1-9=4x-2x
=> -8 = 2x
=> x = -8/2
=> x= -4
hope it's helpful to you ☺️
Answer:
x = -4
Step-by-step explanation:
1+2x=4x+9
1-9=4x-2x
> -8 = 2x
=> -8/2 = x
=> -4 = x

The graph of a rational function can have a vertical asymptote, a horizontal asymptote and a slant asymptote. True or false
9514 1404 393
Answer:
True (or False--see comment)
Step-by-step explanation:
No restrictions were placed on the nature of the rational function, so it is possible to create one that has all three kinds of asymptotes.
The attached graph shows that, along with the rational function whose graph it is. The function's asymptotes are ...
horizontal asymptote: y = 0vertical asymptote: x = -4slant asymptote: y = x -4_____
Additional comment
Our example function makes use of an exponential function. While that can be represented as a polynomial of infinite degree, it would usually not be considered a polynomial. Most authors define a rational function to be the ratio of polynomials.
A ratio of polynomials of finite degree cannot have all three kinds of asymptotes. It can have a vertical asymptote with either a horizontal or slant asymptote, but cannot have both a horizontal and a slant asymptote. The asymptote function is the quotient from the division of the numerator polynomial by the denominator polynomial. Any remainder from that division will necessarily tend to zero as the independent variable gets large.

According to the question;
Miss Kimble earns $42,000 per year.Her state tax rate is 3%In essence, we need to determine how much Miss Kimble pays in state tax.
Therefore,
State tax paid = 3% of $42,000
State tax paid = 0.03 × $42,000
State tax paid = $1,260

Let f(x)=x^2+4
Write a function g whose graph is a reflection in the y-axis of the graph of f.
Answer:
[tex]g(x)=x^2+4[/tex]
Step-by-step explanation:
Hi there!
Given:
[tex]f(x)=x^2+4[/tex]
Let g be a function whose graph is a reflection in the y-axis of the graph of f.
What we need to know:
To reflect a function f in the y-axis, we would need to multiply x by -1:
[tex]g(x)=f(-x)[/tex]
Apply and solve:
[tex]g(x)=(-x)^2+4\\g(x)=x^2+4[/tex]

Number of Tickets
4.
5
Money Spent (5)
80
Answer:
$100
Step-by-step explanation:
4 tickets cost $80.
We divide $80 by 4 to find the cost of 1 ticket.
$80/4 = $20
1 ticket costs $20.
Now we multiply $20 by 5 to find the cost of 5 tickets.
5 * $20 = $100
Answer: $100

If Ann is traveling at 120 km/hr, what
distance does she travel in 10 minutes?
Answer:
20 km
Step-by-step explanation:
120 km an hour = 120 km in 60 minutes
120 = 60
x = 10
120/60 = 2
10*2 = 20
Answer:
20 km.
Step-by-step explanation:
120 km per hour.
An hour is 60 minutes.
To get from 60 to 10, divide 6.
Likewise, to find the distance travelled in 10 minutes, divide 120 by 6.
[tex]\frac{120}{6}= 20[/tex]
Therefore, Ann travels 20 km in 10 minutes.
