A teacher grades 27 tests in 3 hours Find the constant of variation
Answer:
9Step-by-step explanation:
Step one:
given
Let the number of tests graded be g = 27
time taken t = 3 hours
Required
The constant relating the time and the number of tests
Step two:
"The constant of variation is the number that relates two variables that are directly proportional or inversely proportional to one another."
so that the direct variation is
g∝kt
g=t/k
k= g/t
k=27/3
k=9
Answer:
9
Step-by-step explanation:
Since you know that there are 27 tests every three hours then you can divide 27 by 3 to get the constant variation or "test per hour". So then, 27 divided by 3 is 9.
1. If the original price of an item was 75 cents and the new price is 81 cents, 1 pc
what is the percent change? (MAKE SURE YOU TYPE % AT THE END OF
YOUR ANSWER) *
Your answer
Answer:
8%
Step-by-step explanation:
Original Price = 75 cents New Price = 81 cents, % increase = ?
% increase = 81 - 75/75 × 100%
% increase = 6/75 × 100%
% increase = 8% ( Ans)
For a discrete random variable that takes a value of 8 with probability .75 and a value of -4 with probability of .25, what is the expected value and what is the variance
Answer:
5.20
Step-by-step explanation:
X : ______ 8 ____ - 4
P(X) : ___ 0.75 __ 0.25
The expected mean E(x) :
E(x) = ΣX / n
n = sample size = 2
E(x) = (8*0.75) + (-4*0.25)
E(x) = 6 - 1
E(x) = 5
The standard deviation : sqrt(Var(x))
Var(x) = Σx²p(x) - E(x)²
Var(x) = (8^2 * 0.75) + (-4^2 * 0.25)) - 5^2
Var(x) = ((64 * 0.75) + (16* 0.25)) - 25
Var(x) = (48 + 4) - 25
Var(X) = 27
Standard deviation = sqrt(27)
Standard deviation (x) = 5.1961524
Standard deviation = 5.20

12 – n = 23 help I don't get it
Answer:
n = -11
Step-by-step explanation:
Assuming you need to solve for n:
12 - n = 23 (Given)
-n = 11 (Subtract 12 on both sides)
n = -11 (Divide -1 on both sides)
Answer:
n = -11
Step-by-step explanation:
Since 2 negatives create a positive, 12 - -11 would turn into 12 + 11 = 23

The vertex of this parabola is at (-2, 1). Which of the following could be its
equation?
Answer:
A. [tex]x = 4\cdot (y-1)^{2}-2[/tex]
Step-by-step explanation:
From the image attached below statement we understand that a parabola with a horizontal axis of symmetry and whose vertex is centered at [tex]V(x,y) = (h,k)[/tex] is defined by the following expression:
[tex]x-h = C\cdot (y-k)^{2}[/tex] (1)
Where [tex]C[/tex] is the parabola factor, when [tex]C > 0[/tex], the parabola is oriented in the +x direction, otherwise is oriented in the -x direction. Hence, we may conclude that equation of the parabola is of the form:
[tex]x+2 = C\cdot (y-1)^{2}[/tex]
[tex]x = C\cdot (y-1)^{2}-2[/tex], where [tex]C > 0[/tex]
The correct answer is A.
Answer:
A

Which point is coplanar with C, F, and G in the diagram below?
1. H
2.E
3.B
4.D
Step-by-step explanation:
The only face of the cube that has all the points C, F and G is the face CFGD on the right facing outwards.
Hence point D must be coplanar as it is on the same face.
Point D is coplanar with C, F, and G in the diagram of rectangular prism option (4) D is correct.
What is a rectangular prism?It is defined as the six-faced shape, a type of hexahedron in geometry.
It is a three-dimensional shape. It is also called a cuboid.
It is given that:
The rectangular prism is given in the picture.
The rectangular prism is a three-dimensional figure.
As we know, geometry can be defined as the branch of mathematics that is concerned with the size, shape, and orientation of two-dimensional figures.
The cuboid can be defined as a six-faced shape, a type of hexahedron in geometry. It is a three-dimensional shape.
Thus, point D is coplanar with C, F, and G in the diagram of rectangular prism option (4) D is correct.

Determine the coordinates of the intersection of the diagonals of square ABCD with verticals A(-4,6), B(5,6) C(4,-2), and D(-5,-2)
Given:
Vertices of a square are A(-4,6), B(5,6) C(4,-2), and D(-5,-2).
To find:
The intersection of the diagonals of square ABCD.
Solution:
We know that diagonals of a square always bisect each other. It means intersection of the diagonals of square is the midpoint of diagonals.
In the square ABCD, AC and BD are two diagonals. So, intersection of the diagonals is the midpoint of both AC and BD.
We can find midpoint of either AC or BD because both will result the same.
Midpoint of A(-4,6) and C(4,-2) is
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{-4+4}{2},\dfrac{6+(-2)}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{0}{2},\dfrac{6-2}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{0}{2},\dfrac{4}{2}\right)[/tex]
[tex]Midpoint=\left(0,2\right)[/tex]
Therefore, the intersection of the diagonals of square ABCD is (0,2).
Find f(-2) if f(x) = x + x + 7. f(-2) =
Answer:
f(-2) = 9
Step-by-step explanation:
Given that,
f(x) = x² + x + 7
We need to find the value of f(-2).
Put x = -2 in the given function.
f(-2) = (-2)² + (-2) + 7
= 4-2+7
= 9
Hence, the value of f(-2) is equal to 9.

A standard train ticket in a certain city costs $1.50 per ride. People who use the train also have the option of purchasing a frequent rider pass for $17.25 per month. With the pass, a ticket costs only $0.75 per ride. How many train rides a month make the frequent rider pass a better deal than standard train tickets?
Just off the bat 17$is 12 rides and then 17.25 +0.75 is 18 so 13 rides
The number of dimes in Kiara's collection is 13 more than 5 times the
number of quarters in her collection. Kiara has 78 dimes in her
collection. Which equation could be used to find the number of
quarters in Kiara's collection?
78 = 13C + 5
78 = 13C-5
78 = 5C + 13
78 = 5C -13
Answer:
The number of dimes in Kiara's collection is 13 more than 5 times the
number of quarters in her collection. Kiara has 78 dimes in her
collection.
3) 78 = 5C+13is the right answer.
