Suppose your teacher accidentally gives you a multiple-choice calculus test, instead of an Algebra 2 test. There are 40 true-false questions, and you and your classmates answer the questions randomly. The probability of getting an answer correct is 1/2 . You can use 1/2 as the population proportion.
Develop a simulation for answering the 40 questions. Record your results.
Answer:
Step-by-step explanation: You may have a chance of getting 20 questions correct while another 20 wrong. So if you have 1/2 the probability with your class it would be around 20 correct and 20 wrong.
Determine whether \triangle X Y Z is an acute, right, or obtuse triangle for the given vertices. Explain.
X(-7,-3), Y(-2,-5), Z(-4,-1)
The triangle having vertices X(-7,-3), Y(-2,-5), Z(-4,-1) is obtuse.
According to the Pythagorean Inequality Theorem, a triangle whose sides measure a, b, and c where c is the largest, the triangle can be characterized as:
acute if [tex]a^{2} + b^{2} < c^{2}[/tex]
obtuse if [tex]a^{2} + b^{2} > c^{2}[/tex]
right if [tex]a^{2} + b^{2} = c^{2}[/tex]
XY = [tex]\sqrt{(-2 + 7)^{2} + (-5 + 3)^{2} }[/tex]
∴ XY = 5.38
YZ = [tex]\sqrt{(-4 + 2)^{2} + (-1 + 5)^{2} }[/tex]
∴YZ = 4.47
ZX = [tex]\sqrt{(-4 + 7)^{2} + (-1 + 3)^{2} }[/tex]
∴ ZX = 3.60
∴The longest side is XY = 5.38.
Hence, a = YZ, b = ZX and c = XY;
Consider [tex]a^{2} + b^{2}[/tex] :
= [tex]4.47^{2} + 3.60^{2}[/tex]
= 32.94.
Now consider [tex]c^{2}[/tex]:
= [tex]5.38^{2}[/tex]
= 28.94.
Thus, [tex]a^{2} + b^{2} > c^{2}[/tex]
Hence, the triangle is obtuse.

What is the length of HN?
Enter your answer in the box.
Answer:
AH
Step-by-step explanation:
the two lines that are vertical on both lines show that they are both congruent (the same length)
Draw a line segment with endpoints M and R. Now draw a parallel line segment that is the same length as MR¯¯¯¯¯¯¯¯¯ with the endpoints M′ and R′ in the same order.
Which answer correctly describes the transformation from MR¯¯¯¯¯¯¯¯¯ to M′R′¯¯¯¯¯¯¯¯¯¯¯¯?
The required transformation would be in the variable because the slope of parallel lines is always the same.
A line can be defined by the shortest distance between two points is called as a line.
Here,
Line MR is drawn with the endpoints M and R, and another line M'R' is drawn which is parallel to line MR. There is a property of parallel lines that the slope of the parallel lines is always equal. , So the slope of lines are equal there must be a change in variable x and y which describes the translation of the line M'R'.
Thus, the required transformation would be in the variable because the slope of parallel lines is always the same.

In this question,
Paige is choosing between 10 books at the library.
We need to find the probability that she chooses 3 particular books to check out from the 10 initial books.

Mrs. Fields teaches synthetic geometry.
What is synthetic geometry?
The study of geometry without the use of coordinates or equations is known as synthetic geometry, sometimes known as axiomatic geometry or even pure geometry. To make inferences and find solutions, it uses the axiomatic approach and the instruments that are immediately associated to it, namely the compass and straightedge.
Mrs. Fields uses a compass, straightedge, pencil and protractor to teach geometry. And all these are used to either draw or measure and no formulas are needed anywhere, so it is synthetic geometry.

Find x and the measure of each side.
Δ M N P is isosceles with MN ≅ NP. MN is two less than five times x, N P is seven more than two times x , and P M is two more than three times x .
The value of x is 3 and the measure of each side of isosceles ΔMNP is:
MN = 13
NP = 13
PM = 11
We know that, in an isosceles triangle, any two sides of the triangle are equal and the angle opposite to these sides are equal in measure.
In this question, we have been given an isosceles ΔMNP with MN ≅ NP .
Also we have been given some statements about the sides of isosceles ΔMNP.
MN is two less than five times x.
We write above statement as mathematical expression.
MN = 5x - 2
NP is seven more than two times x.
We write above statement as mathematical expression.
NP = 7 + 2x
And PM is two more than three times x.
We write above statement as mathematical expression.
PM = 2 + 3x
As MN = NP
⇒ 5x - 2 = 7 + 2x
⇒ 5x - 2x = 7 + 2
⇒ 3x = 9
⇒ x = 3
So, the value of x is 3.
Now we find the measure of each side of triangle JKL
MN = 5x - 2
MN = 5(3) - 2
MN = 15 - 2
MN = 13
Now the side NP
NP = 7 + 2x
NP = 7 + 2(3)
NP = 13
And side PM would be,
PM = 2 + 3x
PM = 2 + 3(3)
PM = 11
Therefore, the value of x is 3 and the measure of each side of isosceles ΔMNP is:
MN = 13
NP = 13
PM = 11

If the labor force of 165 million people is growing by 1.2 percent this year, how many new jobs have to be created each month to keep unemployment from increasing?
0.165 million jobs must be created monthly to keep unemployment from increasing.
What is the labor force?The combined employed and unemployed population makes up the labor force. The labor force as a percentage of the civilian noninstitutional population is the labor force participation rate.The number of employed persons plus the number of jobless people seeking work is known as the labor force. 1 The unemployed who are not looking for work are not included in the labor pool. For instance, stay-at-home mothers, retirees, and students are not employed.An economy's labor force is calculated as the sum of employed and jobless citizens. As a result, the labor force can be calculated using the formula: labor force = employed population + unemployed population.All employees are included in the labor force, including persons looking for work who are unemployed and the companies who pay their workers. A job seeker would not be regarded as an employee even if she were included in the labor force.How many new jobs have to be created each month to keep unemployment from increasing?
The population of the labor force = is 165 million
Percentage increase of labor force in a year = 1.2 % of 165 million
Percentage increase in the labor force in a month 1.2 %/12=0.1 %= of 155 million
Jobs required to be created each month = population increase each month
165 million *0.1/100=0.165 million
0.165 million jobs must be created monthly to keep unemployment from increasing.

P (pointer landing on neither red nor yellow)
The probability of spinner pointer landing on neither red nor yellow=1/3 .
As given,
Total colors in the spinner is equal to 6
Each color is 2 times
Total number of colored region=6
Number of each red and yellow region=2
Probability
=(Total number of favourable outcomes) / (Total number of outcomes )
Probability of pointer landing on red or yellow is
P(R or Y)=2/6 +2/6
⇒P(R or Y) =2/3
Probability of pointer landing on neither red nor yellow
P( R or Y)' =1-P(R or Y)

1 A map has a scale factor of 1 : 24 000
The distance between two towns is 3.6 km.
How far will this be on the map?
The two towns will be 15 centimeters apart on the map.
Here, we are given that a map has a scale factor of 1:24 000.
This means that if the distance between two points on the map is say 1 meter then in reality, these two points will be 24,000 meters apart.
Now, we are given that two towns are 3.6 kilometers apart
That is in reality, they are 3.6 km away
Let them be x kilometers away on the map
The ratio of the distances on map and in real life must be equal to 1/24,000
⇒ x/3.6 = 1/24,000
x = 3.6/24,000
x = 0.00015 kilometers
or x = 15 centimeters
Thus, the two towns will be 15 centimeters apart on the map.
