A pedagogical research institute wanted to test a new method for teaching geometry by assessing whether It helps students achieve higher grades. They decided to conduct a study using A volunteering high school with a total of 750 students At the beginning of the semester, 2 out of the 4 high schools were randomly picked to use the new teaching method, while the remaining 2 schools kept teaching with traditional methods. The first pair had a total of 400 students, and the second pair had a total of 350 students. By the end of the semester, the researchers compared the average scores in the geometry section of the final exam for each pair of schools. What type of statistical study did the researchers use
Answers
Answer:
Experimental Statistical Study
Step-by-step explanation:
Of the three types of statistical study, the one used by the researcher in this question is the experimental statistical study and the reason is as follows:
From the question, a study was conducted on a total of 4 high schools; these high schools were further divided into 2 pairs.
Each pair were subjected to or experimented with different method of teachings. At the end of the semester, the average were compared.
This implies that both pairs were experimented based on different teaching methods and the result of the methods were measured in order to determine which of the methods is better.
This type of study is experimental
Answer:
Experiment ; No, because the schools could be very different, meaning the randomization won't smooth out other effects.

Angle measures 82.6° less than the measure of its supplementary angle. What is the measure of each angle
Answers
Answer:
131.3°, 48.7°
Step-by-step explanation:
Let x represent the larger angle. Then x-82.6 is the smaller one. Their sum is ...
x +(x -82.6) = 180
2x = 262.6
x = 131.3
x -82.6 = 48.7
The two angle measures are 48.7° and 131.3°.
Question 1 (1 point) Two points on a line are M(4.5) and N(-2,9). Which ratio represents the slope of the line? О а Ob CON -11-13 oc 7
Answers
Answer:
The slope of the line is [tex]-\frac{2}{3}[/tex]
Step-by-step explanation:
Slope:
When we have two points on a line, the slope is given by the change in y divided by the change in x.
Two points on a line are M(4,5) and N(-2,9).
Change in y: 9 - 5 = 4
Change in x: -2 - 4 = -6
The slope is:
[tex]m = \frac{4}{-6} = -\frac{2}{3}[/tex]
The slope of the line is [tex]-\frac{2}{3}[/tex]
Consider the function f(x)=-3x2+12x-5. What is the location of the vertex? Write your answer as an ordered pair.
Answers
Answer:
The (x,y) point of the vertex is usually labelled as:
Vertex = (h, k)
h = -b / 2a
k = ah^2 + bh + c
f(x) = -3x^2 + 12x -5
a = -3 b=12 c=-5
h = -12 / -6 therefore h = 2
k = -3*2^2 + 12*2 -5
k = -12 + 24 -5 therefore k = 7
Vertex (2, 7)

Answer:
The missing angle is 20°
Step-by-step explanation:
The square by the vertex indicates that this is a right angle. A right angle measures 90°. So what you can do is subtract the 70° from the 90°, to get 20°.

Hi there! Your answer is -1/9
Please see an explanation for a better and clear understanding to your problem.
Any questions about my answer and explanation can be asked through comments!:)
Step-by-step explanation:
[tex] \large \boxed{ m = \frac{y_2-y_1}{x_2-x_1} }[/tex]
The formula above is slope formula. We will be using this to find a slope of a line.
From the graph, there are two points which are (4,0) and (-5,1).
You can either let (4,0) = (x1, y1) or (x2, y2) but I will be letting (-5,1) =(x2, y2)
Substitute the coordinate points in.
[tex] \large{m = \frac{1 - 0}{ - 5 - 4} } \\ \large{m = \frac{1}{ - 9} } \\ \large{m = - \frac{1}{9} }[/tex]
Hence, the slope is - 1/9. If you are curious where m-term comes from, it comes from y = mx+b where m = slope and b = y-intercept.

Mr. Gow needs to build a wheelchair access ramp for the school's auditorium. The ramp must rise a total of 3 feet to get from the ground to the entrance of the building. In order to follow the state building code, the angle formed by the ramp and the ground cannot exceed 4.75°.
Mr. Gow plans from the planning department that call for the ramp to start 25 feet away from the building code?
a. Draw an appropiate diagram. Add all the measurements you can. What does Mr. Gow need to find?
b. According to the plan in part (a), what angle will the ramp make with the ground? Will the ramp be to code?
c. If Mr. Gow builds the ramp exactly to code, how long will the ramp be? In other words, at least how far from the building must the ramp start in order to∞ meet the building code? Show all work.
(NOT A MULTIPLE CHOICE)
Answers

Answer:
a. see below for diagram. Angle for the length; length for the angle
b. 6.84°; not to code
c. 36.1 ft
Step-by-step explanation:
a. The diagram is shown below. Mr. Gow needs to find the angle it makes in order to determine if it is up to code. Alternatively, Mr. Gow needs to find the required length for a ramp that meets code.
__
b. The angle the ramp makes can be found using the tangent relation.
Tan = Opposite/Adjacent
tan(angle) = 3/25
angle = arctan(3/25) ≈ 6.84°
The ramp will make a 6.84° angle with the ground. It will not meet code.
__
c. We can find the distance from the building where the ramp must start using the same trig relation.
tan(4.75°) = (3 ft)/(distance)
distance = (3 ft)/tan(4.75°) ≈ 36.1 ft
The ramp must start 36.1 feet from the building to exactly meet code.

What is an angle?In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.
here, we have,
from the given figure, we get,
The triangle is isosceles,
so 180-72= 108.
and, we know,
∠J=∠L
So,
108/2=54
Hence, The solution is, m KJL=54 degrees.
