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).

Answer:
First, second, third, and fourth are functions
Step-by-step explanation:
Each input in the first, second, third, and fourth only have one output. In the fifth one 3.3 and 6.6 are seen twice as the x-value, so this is incorrect.
(answered this on your other question, but I will put it here too!)
Cada entrada en la primera, segunda, tercera y cuarta tiene solo una salida. En el quinto, 3.3 y 6.6 se ven dos veces como el valor de x, por lo que esto es incorrecto.

what are the x and y intercepts for the line: 4x-24=10 leave your answers in coordinate point form ( , ) ( , )
Answer:
(2.5, 0) and (0, - 5)Step-by-step explanation:
The line is:
4x - 2y = 10The x- intercept is the value of x, when y = 0:
4x - 2*0 = 104x = 10x = 2.5The y- intercept is the value of y, when x = 0:
4*0 - 2y = 10- 2y = 10y = - 5x intercept
4x-10=04x=10x=10/4x=5/2(2.5,0)
y intercept

Answer:
b. Complementary gas masks
Step-by-step explanation:
Adjacent means that the two angles are right next to each other and touching. The two angels in the photo are touching. Supplementary means that the two angels can for together to make a 180 degree line. The two angels in the photo make a 180 degree line. Complementary means that the two angels make a 90 degree angel. Since the two angels already make a 180 degree angels then, they cannot make a 90 degree angel. The question is asking for what it is not so, complements would be the answer.

The pizza costs $9.75 each you buy 3 pizzas and eat 1/5. How much pizza did you eat? how much pizza is left over? helpp
Answer:
1/5 pizzas; 2 4/5 pizzas
Step-by-step explanation:
the cost is unneeded information
if you bought 3 pizzas but only ate 1/5 of a pizza you subtract them
3 - 1/5 is 2 4/5 or 2.8
you ate 1/5 of the pizzas and have 2 4/5 left
Step-by-step explanation:
You bought 3 pizzas.
You ate 1/5. It can be as 1/5 of one pizza or 1/5 of all pizzas.
The first case:
3 - 1/5 = 2 4/5 pizzas leftThe second case:
3 - 1/5*3 = 3 - 3/5 = 2 2/5 pizzas leftEmilio’s paycheck was $305.25, and he makes $9.25 per hour. How many hours did Emilio work
Find point slope form with 1/4 passing through (-7,-5)
Answer:
y+5 = 1/4(x+7)
Step-by-step explanation:
Point slope form is
(y-y1) = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y- -5 = 1/4(x - -7)
y+5 = 1/4(x+7)
Hello There!
Point-Slope:
y-y₁=m(x-x₁)
y-(-5)=1/4(x-(-7)
y+5=1/4(x+7)
y=1/4x+1.75+5
y=1.4x+6.75

The correct answer of 500 divided by 1.25 is 2.5 how ?
Answer:
400
not 2.5
Step-by-step explanation:
500 / 1.25
= ( 500 / 1.25 ) x ( 100 / 100 )
= ( 500 x 100 ) / ( 1.25 x 100 )

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.

Answer:
3.75
Step-by-step explanation:
Angle 2 and angle 3 are supplementary angles, so we can add them together and put it equal to 180°
Equation:
30x + 14 + 10x + 16 = 180
Combine like terms:
40x + 30 = 180
Subtract 30 from both sides:
40x = 150
Divide both sides by 40:
3.75
Check:
Take the orginal equation:
30x + 14 + 10x + 16 = 180
Plug in for x:
30(3.75) + 14 + 10(3.75) + 16 = 180
Solve:
112.5 + 14 + 37.5 + 16 = 180
180 = 180 ✅

A prime number is a number that is only divisible by 1 and itself.
13 is only divisible by 1 and itself.
37 is only divisible by 1 and itself.
47 is only divisible by 1 and itself.

(a) Write the point–slope form of a function that has a slope of 3- 5 and passes through the point (6,1).
(b) Algebraically manipulate your answer in part a to produce the slope– intercept form of the function that has a slope of 3 - 5 and passes through the point (6,1).
The question illustrates linear equation
The equation in point slope form is: [tex]\mathbf{ y - 1 = \frac 35 (x - 6)}[/tex]The equation in slope intercept form is: [tex]\mathbf{ y = \frac 35x - \frac{13}5}[/tex]The given parameters are:
[tex]\mathbf{m = \frac 35}[/tex] --- the slope
[tex]\mathbf{(x_1,y_1) = (6,1)}[/tex] -- the point it passes through
(a) The equation in point slope form
This is represented as:
[tex]\mathbf{ y - y_1 = m(x - x_1)}[/tex]
Substitute known values
[tex]\mathbf{ y - 1 = \frac 35 (x - 6)}[/tex]
So, the equation in point slope form is: [tex]\mathbf{ y - 1 = \frac 35 (x - 6)}[/tex]
(a) The equation in slope intercept form
In (a), we have:
[tex]\mathbf{ y - 1 = \frac 35 (x - 6)}[/tex]
Open brackets
[tex]\mathbf{ y - 1 = \frac 35x - \frac{18}5}[/tex]
Add 1 to both sides
[tex]\mathbf{ y = \frac 35x - \frac{18}5 + 1}[/tex]
Take LCM
[tex]\mathbf{ y = \frac 35x + \frac{-18 + 5}5}[/tex]
[tex]\mathbf{ y = \frac 35x + \frac{-13}5}[/tex]
[tex]\mathbf{ y = \frac 35x - \frac{13}5}[/tex]
Hence, the equation in slope intercept form is: [tex]\mathbf{ y = \frac 35x - \frac{13}5}[/tex]
