The value of x is 45 degree and value of y is 49 degree.We can find by using supplementary and corresponding angles.
What is supplementary angle with example?Supplementary angles are those angles that sum up to 180 degrees. To find the angle which is supplementary to another angle subtract the given angle from 180 degrees. For example if one angle is 60 degrees then another angle is 180 – 60 = 120 degrees.
What is a corresponding angle example?Corresponding angles are the angles that are formed when two parallel lines are intersected by the transversal. The opening and shutting of a lunchbox, solving a Rubik's cube, and never-ending parallel railway tracks are a few everyday examples of corresponding angles.
Now we find
according to supplementary angles
3x+45=180
3x=180-45
x=45
According to corresponding angles
y-4=45
y=45+4
y=49

What is the length of AB?
Round to one decimal place.
Answers
Answer:
5.4
Step-by-step explanation:
"The 'Angle Bisector' Theorem says that an angle bisector of a triangle will divide the opposite side into two segments that are proportional to the other two sides of the triangle."
thus,
DB/AB = DC/AC
2.8/AB = 3/5.8
multiply both sides by AB to make it a numerator
2.8 = 3*AB/5.8
multiply both sides by 5.8/3 to isolate AB
2.8 * 5.8/3 = AB = 5.413 ≈ 5.4
Therefore , the solution of the given problem of triangle comes out to be
AB length = 5.4 units.
Defining a triangleIn a plane, any three points can be joined to form triangles, which have three sides and three angles. They were among the first geometrical forms to be investigated. Because each polygon, regardless of its number of sides (four, five, six, or n), may be divided into a triangle, they are especially significant.
Here,
According to the "Angle Bisector Theorem," a triangle's opposing side will be divided into two segments that are proportional to the other two sides.
thus,
DC/AC = DB/AB.
2.8/AB = 3/5.8
By multiplying both sides by AB, the numerator is created.
2.8 = 3*AB/5.8
To distinguish AB, multiply both sides by 5.8/3.
2.8 * 5.8/3 = AB = 5.413 ≈ 5.4
Therefore , the solution of the given problem of triangle comes out to be
AB length = 5.4 units.

What range of values is not a possible scale factor (k)?
A) k 1
D) all are possible
Answers
A range of values which is not a possible for scale factor (k): k = 0
We know that the scale factor is the number (also called the conversion factor) which is used to change the size of a figure without changing its shape.
It is used to expand or compress the size of an object.
The scale factor formula is:
Scale factor = Dimensions of the transformed shape ÷ Dimensions of the original shape
If the scale factor k > 1, the object is enlarged.
If the scale factor is 0< k <1, the object is compressed.
If the scale factor is k = 1, the shape of object remains the same.
And the scale factor cannot be zero.

use your answer in part (a) to find the two values of m for which (m-2)2 -4(m-2)+2=0
Answers
Answer:
Step-by-step explanation:
Replace m - 2 with x. Then we have x^2 - 4x + 2 = 0.
Completing the square, we get x^2 - 4x + 4 - 4 + 2 = 0, or
x^2 - 4x + 4 - 2 = 0, or
(x - 2)^2 - 2 = 0, or (x - 2)^2 = 2
Solve for x: Take the square root of both sides. Then:
x - 2 = ±√2 and x = 2 + √2 and x = 2 - √2
But x = m - 2; therefore, x = m - 2 = 2 - √2. Solving for m, we get
m = 4 - √2.
Also: m - 2 = 2 + √2 leads to m = 4 + √2.
The given equation is true for these two values of m.

Answer:
a(n) = 20*2.5^(n - 1)
Step-by-step explanation:
Note that 50 is 2.5 times 20, and that 125 is 2.5 times 50. Thus the common factor is 2.5. The formula for the nth term is
a(n) = a(1)*r^(n - 1) => a(n) = 20*2.5^(n - 1)
Using a pencil
, pair of compasses and ruler, construct a triangle with sides 7cm,5cm and 6cm.
Measure the size of the angle between the 5cm and 7cm sides to the nearest degree.
Answers
The angle between the 5cm and 7cm sides to the nearest degree should measure approximately 71 degrees.
To construct a triangle with sides 7cm, 5cm and 6cm, start by drawing a straight line of 7cm length using the ruler. Next, use the compasses to draw an arc from one end of the line, with a radius of 5cm. Then, draw another arc from the same point of the line, with a radius of 6cm. Where the arcs intersect, draw a straight line connecting them to complete the triangle.
To measure the size of the angle between the 5cm and 7cm sides, use the compasses to draw a small arc from the vertex of the angle, and measure the angle using the ruler. To ensure accuracy, divide the angle into smaller, easier-to-measure angles. Repeat the process until the angle is measured to the nearest degree. In this case, the angle between the sides of 5cm and 7cm is approximately 71 degrees.

What does y 3x 3 look like on a graph?
Answers
On a graph, y 3x 3 would be a line that is 3 units below the line y = 3x. It would have the same slope but lower y-intercept.
To graph y 3x 3, we can first graph y = 3x. To do this, we can pick any two points along the line and plot them. For example, if we choose (0,0) and (1,3), the line would look like this:
(0,0) -------------------------- (1,3)
Now, to graph y 3x 3, we want to move the line 3 units down. Therefore, the new points that we plot should be (0,-3) and (1,0). The graph should look like this:
(0,-3) -------------------------- (1,0)
This line is 3 units below the line y = 3x. It has the same slope, but a lower y-intercept.

7. The terminal side of theta, and angle in standard position, intersects the unit circle at
P(-) What is the value of csc?
Answers
Complete question is;
The terminal side of angle θ in standard position, intersects the unit circle at P(-10/26, -24/26). What is the value of csc θ?
Answer:
csc θ = -13/12
Step-by-step explanation:
We know that in a unit circle;
(x, y) = (cos θ, sin θ)
Since the the terminal sides intersects P at the coordinates P(-10/26, -24/26), we can say that;
cos θ = -10/26
sin θ = -24/26
Now we want to find csc θ.
From trigonometric ratios, csc θ = 1/sin θ
Thus;
csc θ = 1/(-24/26)
csc θ = -26/24
csc θ = -13/12

Suppose that a recent poll found that 47% of adults believe that the overall state of moral values is poor. For 350 randomly selected adults, compute the mean and standard deviation of the random variable X, the number of adults who believe that the overall state of moral values is poor. What is the mean of X and the standard deviation of X?
Answers
Answer:
The mean of X is 164.5 and the standard deviation is 9.34.
Step-by-step explanation:
For each adult, there are only two possible outcomes. Either they believe that the overall state of moral values is poor, or they do not. The probability of an adult believing this is independent of any other adult, which means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
The standard deviation of the binomial distribution is:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]
Suppose that a recent poll found that 47% of adults believe that the overall state of moral values is poor.
This means that [tex]p = 0.47[/tex]
350 randomly selected adults
This means that [tex]n = 350[/tex]
What is the mean of X and the standard deviation of X?
Mean:
[tex]E(X) = np = 350*0.47 = 164.5[/tex]
Standard deviation:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{350*0.47*0.53} = 9.34[/tex]
The mean of X is 164.5 and the standard deviation is 9.34.
Work out the size angle BCD
Answers
By using the fact that the interior angles should add up to 360°, we will see that:
C = 142°
How to find the missing angle?We know that for any polygon of N sides, the sum of the interior angles is equal to:
S = (N - 2)*180°
In this case, the polygon has 4 sides, then:
S = (4 -2)*180° = 360°
Then we can write the equation:
A + B + C + D = 360°
Replacing the known angles we get:
68° + 43° + C + 107° = 360°
And now we can solve this for C.
C = 360° - 107° - 43° - 68°
C = 142°
That is the measure of the angle BCD.

Distributions that are negatively skewed are also known as left-skewed distributions.
This is due to the number line having a significant negative tail.
Additionally, the peak is to the left of the mean.
The right tail of a right-skewed distribution is lengthy.
It's a widespread misperception that "peakness" is defined by the distribution's peak.
To put it another way, a peak that leans left indicates a left-skewed distribution.
