How is Pythagorean theorem and geometric mean related?
Answer:
The two triangles formed are also similar to each other. The measure of the altitude drawn from the vertex of the right angle to the hypotenuse is the geometric mean between the measures of the two segments of the hypotenuse.

Twelve less than the cube of the sum of six times a number and three.
Answer:
[tex](6 * n + 3)^{3}[/tex] - 12
Step-by-step explanation:
Twelve less than the cube of the sum of six times a number and three.
1. Change the words into numbers and math symbols.
Twelve = 12
Less than = subtract -
sum of six times a number and three = (6 * n + 3)
cube = exponent 3
2. Write the problem.
[tex](6 * n + 3)^{3}[/tex] - 12

Identify at least one confounding variable that undermines the conclusion drawn in the following fictional study:
Prof. Acosta was interested in which of two popular statistics textbooks (Statistics: It Will Change Your Life and Statistics: Bigger, Better, Stronger) was better for students. Prof. Acosta compared the two texts by assigning one text to a section of statistics taught by Prof. Agnew from 10 to 11 a.m. on Monday, Wednesday, and Friday, and the other text to a section of statistics taught by Prof. Alvarez from 7 to 10 p.m. on Wednesday evenings. At the end of the term, all students took the same comprehensive test. Students to whom Statistics: Bigger, Better, Stronger was assigned performed better on the test than did students to whom Statistics: It Will Change Your Life was assigned. Therefore, Prof. Acosta concluded that the former textbook was the better one.
Answer:
Identifying at least one confounding variable that undermines the conclusion drawn in the fictional study is:
All students took the same comprehensive test.
Step-by-step explanation:
In a study, an independent variable causes an effect on the dependent variable. But a confounding variable is the variable that influences the independent variable as well as the dependent variable. If this third variable is not controlled, it might lead the researcher to make a wrong estimate of the relationship that exists between the independent variable and the dependent variable.

Answer:
80
That's the answer
Step-by-step explanation:
No explanation
Answer: 80 meters
Step-by-step explanation:
There are two ways you could do this.
1st way (my personal way of doing it): Add 25 + 15 + 25 + 15. Then subtract that by 9 + 7 + 9 + 7 (you do this because that will find the perimeter of the open space.)
=> 25 + 15 + 25 + 15 = 80
=> 9 + 7 + 9 + 7 = 32
=> 80 - 32 = 48
2nd way: Add 25, 15, 16 and 8. (You are adding the sides that they already give you.) Then, you would find the missing sides (or the sides that don’t have a number on the .) And that would be 7 and 9. So you add the sum of those two numbers to your answer.
=> 25 + 15 + 16 + 8 = 64
=> 7 + 9 = 16
=> 64 + 16 = 80
This might be very confusing but I hope this helps :’)

Given the statement ΔQRS ≅ ΔXYZ, list all congruent parts you can conclude about the two triangles. Explain.
Answer:
Side QR is congruent to Side XY.
Side RS is congruent to Side YZ.
Side SQ is congruent to Side ZX.
Angle Q is congruent to Angle X.
Angle R is congruent to Angle Y.
Angle S is congruent to Angle Z.
Step-by-step explanation:
Side QR is congruent to Side XY because triangle QRS is congruent to triangle XYZ and each point of a triangle is in corresponding order with a point of the other triangle. For example, Q matches up with X since they both are listed first in their respective sequence.

A. 20−(4/9×3)
B. (4/9×20)−3
C. 4/9×(20−3)
D. 3−(4/9×20)
Answer:
B) (4/9 x 20)-3
A and B are complementary angles. If m_A= (2x + 10)° and m
ZB = (3x + 15)°, then find the measure of ZB
Step-by-step explanation:
<A + < B = 90° { being complementary angles)
2x + 10° + 3x + 15° = 90°
5x = 90° - 15° - 10°
5x = 65°
x = 13°
Now
<B = 3x + 15° = 3 *13° + 15° = 54°

28 is 50% of what number?
Answer:
its 56
Step-by-step explanation
50% × x = 28 or, 50 100
× x = 28
Multiplying both sides by 100 and dividing both sides by 50,
we have x = 28 ×
100
50
x = 56
If you are using a calculator, simply enter 28×100÷50, which will give you the answer.

Hello! I’m struggling with this question just if someone could help me!
Answer:
Assuming the question is about the area of the "house" it's 70.
Step-by-step explanation:
The triangle's height is 18 - 10 = 8
The area of the rectangle is 5 * 10 = 50
The area of the triangle is 5 * 8 / 2 = 20
The total area is 50 + 20 = 70

In a class where there are a total of 80 pupils, 20 are girls and the remaining
are boys. What percent of the class are boys?
Answer:
75%
Step-by-step explanation:
First find the number of boys.
80 - 20 = 60
Now find the percentage my taking the number of boys upon the total, times that by 100 which gives the percentage.
[tex]\frac{60}{80}[/tex] × 100 = 75%

Ten students from a class participated in a math quiz. The scores obtained by
them were recorded as follows.
11, 6, 7, 13, 1, 13, 16, 7, 13, 16
Mean :
Median :
Mode :
Range :
Answer:
Mean: 10.3
Median: 12
Mode: 13
Range: 15
Step-by-step explanation:
First, let's define what all these terms mean.
Mean is the average of all the numbers in a set of data. Median is the number in the middle of a range whenever the numbers are put in ascending order. If there are two numbers in the middle instead of one, then take the average of those two numbers. Mode is the number that occurs the most in the set of data. Range is the difference between the largest and the smallest number in a set of data.
To make things a little easier overall, let's just go ahead and put all our numbers in ascending order, which will be as follows: 1, 6, 7, 7, 11, 13, 13, 13, 16, 16.
To find the mean, just add up all the numbers and divide by how many there are. So we'll add 1 + 6 + 7 + 7... and so on to get a total of 103. Next, we'll divide that number by 10 since there are 10 students. This gives us a mean of 10.3.
Next, we'll find the median. To find this, just figure out which number(s) is in the center of your data. Since we have an even number of terms (10), we'll have two numbers in the middle, being 11 and 13. To find our median from here, just add 11 and 13 and then divide by 2. 11 + 13 = 24 and then 24 / 2 = 12. This means that our median is 12.
Next, we'll find the mode. The mode is the number that is seen the most in a set of numbers. In our set, we see that there are three 13s. Since 13 is the most frequently used number in our set, this makes it the mode.
Finally, we'll find the range. The range is just the largest number in the set minus the smallest number in the set. In our set, 16 is our largest number and 1 is our smallest. Just do 16 - 1 = 15 and we'll see that 15 is the range of the set. Hope this helps!

find the slope of the line that passes through the points (1,-4) and (3,-1)
Answer:
The slope is 3/2 or 1.5
Step-by-step explanation:
The slope is Rise/Run.
The difference in y-values, –1 -(-4) =3 is the rise.
the difference in x-values, 3 –1 = 2 is the run.
