You have read 4 of the books shown. Which choice shows 2 ways of writing the fraction of these books that you read?
Using proportions, two ways of writing the fraction of these books that you read is:
4/12 and 1/3.
What is a proportion?A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using basic arithmetic operations, especially multiplication or division.
One example of application of proportions is for relative frequencies, as a relative frequency is given by the number of successes in the sample divided by the sample size.
In the context of this problem, it is found that:
The number of successes on the sample is of 4, as you have read 4 books.The sample size is of 12, as there is a total of 12 books.Hence the relative frequency is:
4/12.
12 is divisible by 4, hence the fraction can be simplified as follows:
1/3.
Missing informationThe number of books is missing, and is of 12. (researching the problem on a search engine).

and we have the coordinates of end points ,
that is x₁[tex]=[/tex] -1 , y₁=2 and x₂=5 , y₂ = 8 and the ratio m=2 and n=1 .
Substituting the above values in the section formula ,
which states that the coordinate of point C will be

Let g be a group with normal subgroups m and n. furthermore, assume n is a subste of m. use the first isomorphic theorem to prove that (g/n)/(m/n) is isomorphic to g/m.
The proof of (g/n)/(g/m) isomorphic to g/m from the first isomorphism theorem is as shown below.
Let a group g with normal subgroups m and n. Furthermore, n is a subset of m.
Proof: We have to prove (g/n)/(m/n) ≅ g/m (1)
g/m and g/n are valid because m and n are normal in g. As normality satisfies the intermediate subgroup condition, n is normal in m. because normality is image-closed m/n is a normal subgroup in g/n. Under the quotient map by n, the normal subgroup m of g is sent to a normal subgroup m/n of g/n. Thus the L.H.S of the statement to prove makes sense.
To describe the isomorphism from the left side to the right side
φ: g/n \to g/m
ψ(gn) = gm
So, a coset of n is taken by the map and it gives the corresponding coset of m. This is well-defined, because if h∈ n, thus h∈ m, hence (gh)m = g(hm) = gm.
The map is a homomorphism. So we observe that it maps the identity element to the identity element, keeps group multiplication preserved, and also preserves the inverse map.
Also, the map is surjective because any coset gm is present as the image of gn under ψ.
Lastly, we need to find the kernel of the map which is given by the set of gn such that gm = m. This is those cosets of n that are in m, and this is the same as the coset space m/n. Thus the kernel of the map is exactly g/m. Thus, the surjective homomorphism ψ: g/n → g/m has kernel m/n. And now by the first isomorphism theorem
(g/n)/(m/n)≅g/m where ≅ shows isomorphism

Write the equation of the line that passes through the given points.
1,2.5) and (0,-1.5)
Answer:
y = 4x - 1.5
Step-by-step explanation:
We need to find the slope (m) and the y-intercept (b), if we are writing this in the slop intercept form of a line.
y =mx + b
The slope is the change in y over the change in x.
The two points give us the y's ad x's
The y's are: -1.5 and 2.5
The x's are: 0 and 1
[tex]\frac{-1.5 - 2.5}{0-1}[/tex] = [tex]\frac{-4}{-1}[/tex] = 4 A negative divided by a negative is a positive.
We have the slope. The slope is the point (0,b). We are given that point.

The coordinates of the rotated triangle will be (2, - 2) , (3, -8) , (7, 0)
What is translation of graph?Function translation takes a function (and its graph) and, by adding and subtraction, moves the graph around the plane without changing its shape.
Given is a triangle coordinate on x - y plane.
The rule (x, y) → (- x, - y) represents the rotation of a figure by 180 °.
Now, initially the coordinates of the triangle are -
(-2, 2) , (-3, 8) , (-7, 0)
After transforming the graph by the rotation of 180°, the new coordinates will be -
(2, - 2) , (3, -8) , (7, 0)
Plot the coordinates on the graph and you will get the rotated image.
Therefore, the coordinates of the rotated triangle will be (2, - 2) , (3, -8) , (7, 0).

the 10th and 15 term of an AP are - 5 and - 7 1/2 respectively what is the sum of the first 20 terms ? I really need the answer pls A 60 B -105 C -52 1/2 D -20
Answer:
B
Step-by-step explanation:
before finding the sum we require to find first term and common difference.
the nth term of an AP is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
given a₁₀ = - 5 and a₁₅ = - 7 [tex]\frac{1}{2}[/tex] = - 7.5 then
a₁ + 9d = - 5 → (1)
a₁ + 14d = - 7.5 → (2)
subtract (1) from (2) term by term to eliminate a₁
0 + 5d = - 2.5
5d = - 2.5 ( divide both sides by 5 )
d = - 0.5
substitute d = - 0.5 into (1) and solve for a₁
a₁ + 9(- 0.5) = - 5
a₁ - 4.5 = - 5 ( add 4.5 to both sides )
a₁ = - 0.5
the sum to n terms of an AP is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
here a₁ = - 0.5 and d = - 0.5 , then
S₂₀ = [tex]\frac{20}{2}[/tex] [ (2 × - 0.5) + (19 × - 0.5) ]
= 10 (- 1 -9.5)
= 10 × - 10.5
= - 105
What is the value of this expression
Plug in the values in the right positions. And simplify.
[tex] = \frac{1}{2} (12 \times \frac{1}{4} ) - \frac{1}{2} \\ = \frac{1}{2} (3) - \frac{1}{2} \\ = \frac{3}{2} - \frac{1}{2} \\ = \frac{2}{2} \\ = 1[/tex]

Define Trigonometric functions
A right-angled triangle's angle can be related to side length ratios using real-world trigonometric functions.
We know the formula of sin(A - B) = sinAcosB - cosAsinB
And the given expression is
sin (π/12)cos(7π/12) -cos(π/12)sin(7π/12)
Which is in the form of given formula of sin(A - B)
where, A = π/12 and B = 7π/12
put A and B values in sin(A - B),
sin(π/12 - 7π/12) = sin (π/12)cos(7π/12) -cos(π/12)sin(7π/12)
sin(-6π/12) = sin (π/12)cos(7π/12) -cos(π/12)sin(7π/12)
sin(-π/2) = sin (π/12)cos(7π/12) -cos(π/12)sin(7π/12)
Hence, sin (π/12)cos(7π/12) -cos(π/12)sin(7π/12) is equivalent to sin(-π/2).

The average number of miles driven on a full tank of gas before its low fuel light comes on is ( μ )= 320
It follows the standard deviation of ( δ ) = 30
For the normal distribution,

Bobby photographs a bird. If the bird, that measures 3.4 inches in the photo, is actually 3.75 feet tall, approximately how long is its boak if it measures 0.4 inches in the
photo?
We need to know about scaling of measurements to solve the problem. The length of the bird's beak is 5.29 inches.
In the given question we know that the height of the bird in the photo is 3.4 inches and the real height of the bird is 3.75 feet. We know that the length of the beak in the photo is 0.4 inches, we need to find out the real length of the beak. We need to find by how much the measurement of the bird is scaled down to fit in the photo. We need to convert feet to inches first to get the scaling factor, we can then divide the length of the beak given by the scaling factor.
3.75 feet= 3.75x12 =45 inches
scaling factor= 3.4/45=0.0756
real length of beak=0.4/0.0756=5.29 inches
