Given that MTW = CAD, which segments are corresponding parts of the congruent triangles?
Answer: MW = CD
Explanation: It would be this way because if you wrote the triangles out, MW would be in the same place as CD, making them corresponding.
The following segments are corresponding parts of the congruent triangles.
segment MT ≅ segment CA
segment TW ≅ segment AD
segment MW ≅ segment CD
What are congruent triangles?Two triangles are said to be congruent if pairs of their corresponding sides and their corresponding angles are equal. They are of the same shape and size.
Given that
Triangle MTW = Triangle CAD
If two triangles are congruent then the corresponding sides and corresponding angles are congruent.
∴ segment MT ≅ segment CA
{corresponding parts of the congruent triangles}
segment TW ≅ segment AD
{corresponding parts of the congruent triangles}
segment MW ≅ segment CD
{corresponding parts of the congruent triangles}

A research organization reported that 41 percent of adults who were asked to describe their day responded that they were having a good day rather than a typical day or a bad day. To investigate whether the percent would be different for high school students, 600 high school students were randomly selected. When asked to describe their day, 245 students reported that they were having a good day rather than a typical day or a bad day. Do the data provide convincing statistical evidence that the proportion of all high school students who would respond that they were having a good day is different from 0.41 ?
A) No, because the p value is less than any reasonable significance level
B) No, because the pvalue is greater than any reasonable significance level
C) Yes, because the p-value is less than any reasonable significance level
D) Yes, because the pvalue is greater than any reasonable significance level
E) Yes, because the expected value of the number of students who will report having a good day is 246, not 245.
Answer:
B) No, because the p-value is greater than any reasonable significance level
Step-by-step explanation:
H-null: p = 0.41
H-alt: p =/= 0.41
1 proportion Z test
On a calculator: stat + tests + 5
p: .41
x: 245
n: 600
prop: =/= p
This gives a p-value = .934
(standard significance level is .05, so this p-value is much larger)
fail to reject H-null
If the p-value is much larger than 0.41 then the null hypothesis is rejected. Then the correct option is B.
What are null hypotheses and alternative hypotheses?In null hypotheses, there is no relationship between the two phenomenons under the assumption or it is not associated with the group. And in alternative hypotheses, there is a relationship between the two chosen unknowns.

Null hypotheses
p = 0.41
Alternative hypotheses
p ≠ 0.41

Looking out from a balcony, the angle of elevation to the top of the next building is
approximately 22 degrees. The angle of depression to the bottom of the building is
approximately 29 degrees. If the building is 200 feet away, how tall is it?
Answer:
191.67 feets
Step-by-step explanation:
From. The attached picture :
Height x can be obtained using trigonometry :
Tan 22 = x / 200
0.4040262 = x / 200
x = 0.4040262 * 200
x = 80.805245 feets
For height, y :
Tan 29 = x / 200
0.5543090 = x / 200
y = 0.5543090 * 200
y = 110.86181 feets
Building height = x + y
Building height = 80.805245 + 110.86181 = 191.67 feets

Graph the linear equation q(x)=-3x+1
The linear function q(x) = -3x + 1 is graphed and attached
How to graph the linear functionThe graph of the linear function is a straight line graph and the table of values used in making the plot is calculated as follows
For x = -20, q(x) = -3 * -20 + 1 = 61
For x = -10, q(x) = -3 * -10 + 1 = 31
For x = 0, q(x) = -3 * 0 + 1 = 1
For x = 10, q(x) = -3 * 10 + 1 = -29
For x = 20, q(x) = -3 * 20 + 1 = -59
Table of values
x y
-20 61
-10 31

These points are plotted in the cartesian coordinate by tracing the point of intersection of the x and y and marking it. Then the marked points are joined together to form a straight line

Answer:
This looks like a UNIFORM distribution. There is no skewed and it's not a 'normal' distribution, which would be like a hill. does that make sense?
The image is showing the uniform distribution. The correct option is D.
What is uniform distribution?The continuous uniform distribution or rectangular distribution is a family of symmetric probability distributions in probability theory and statistics. The distribution describes an experiment in which the outcome is arbitrary and falls between certain bounds.
It can be also defined as a uniform distribution is a type of probability distribution in which every possible outcome has an equal chance of occurring.
Given that the in the image there are vertical bars showing the approximate uniformity of the data.
Here, the data is varying uniformly therefore the shape is describing the uniform distribution.

the distance around a square room measures 101 feet 7 inches. Estimate the length of each side of the room
Answer:
304.75 inches
Step-by-step explanation:
Total distance = 101 feet 7 inches
Recall :
1 Feet = 12 inches
Total distance in inches = (101 * 12) + 7 = 1219 inches
Perimeter of square = 1219
Sides of a square are always equal
Number of sides = 4
Hence, length of each side = 1219 inches / 4 = 304.75 inches

Given:

To find:
The length of side c.
Solution:
According to the angle sum of property of a triangle, the sum of all interior angles of a triangle is 180 degrees.
[tex]m\angle A+m\angle B+m\angle C=180^\circ[/tex]
[tex]15^\circ+m\angle B+120^\circ=180^\circ[/tex]
[tex]m\angle B+135^\circ=180^\circ[/tex]
[tex]m\angle B=180^\circ-135^\circ[/tex]
[tex]m\angle B=45^\circ[/tex]
According to the Law of sines,
[tex]\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]
Using Law of sines, we get
[tex]\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]
[tex]\dfrac{3}{\sin 45^\circ}=\dfrac{c}{\sin 120^\circ}[/tex]
[tex]\dfrac{3}{\dfrac{1}{\sqrt{2}}}=\dfrac{c}{\dfrac{\sqrt{3}}{2}}[/tex]
[tex]3\sqrt{2}\times \dfrac{\sqrt{3}}{2}=c[/tex]

The equation of the straight line in slope - intercept form that
is perpendicular to the given line and passes through the point (0, 9) is -
y = 6x + 9.
What is the general equation of a straight line?The general equation of a straight line is -
y = mx + c
where -
{m} is the slope of the line.
{c} is the {y} - intercept.
Given is that the equation of a straight line as -
2x + 12y = - 1
Assume that the equation of the straight line in slope - intercept form as
y = mx + c
Now, the given straight line is perpendicular to the given line. So, we can write the slope as -
{m} = -1/(-1/6)
{m} = 6
For the {y} intercept, we can write -
{c} = 9
So, we can write the equation of the straight line in slope - intercept form that is perpendicular to the given line and passes through the point (0, 9) is -
y = 6x + 9
Therefore, the equation of the straight line in slope - intercept form that
is perpendicular to the given line and passes through the point (0, 9) is -
y = 6x + 9.

5x1 = 5 (5 + 0)
5x2 = 10 (5 + 5)
5x3 = 15 (5 + 5 + 5 [10 + 5])
5x4 = 20 (5 + 5 + 5 + 5 [15 (5x3) + 5)
