Answer:
It is the MEAN
Step-by-step explanation:
Mean, median and mode given in the question are all used to measure central tendency of a given data. From the sets of data given, and from the values of the mean, median and mode (8.8, 8.85 and 8.9 respectively) it can be summarized that these values points the center of the sets of data trying to estimate the average.
MEAN is the statistic that reflects a typical score because when we look at the data (8.2, 8.7, 8.8, 8.8, 8.9, 8.9, 8.9, 9.2), it easily gives us the average score. Since mean = addition of the data value / the number of the data, it gives us Kathleen average score since it takes all the judges scores into consideration giving us the typical score. Unlike mode that only use most occured data meaning it doen't use all the data and as such may not show the true average of the scores. Also, mode is not consistent when it comes to small number of data especially if no score occur most or we have more than one mode. It is not median because of the small number of scores (data).

Hello!!! Princess Sakura here ^^
Step-by-step explanation:
Since those two angles are corresponding that means they are equal to each other so we write an equation like this...
[tex]7x+9=8x+2[/tex]
Now we solve for x...
[tex]7x+9=8x+2\\9=x+2\\x=7[/tex]
And that's it x will equal 7.

What is a density curve?
The density curve is a way of representation of numerical distribution data in graphical manner, where the outcomes are continues. The density curve can not be below the x-axis or horizontal line of the graph.
In a density curve,
The mean of a density curve is indicated by μ (mu).The standard deviation of a density curve is indicated by Sx.The density curve can only be above x-axis and not below it.Thus, the statements which are true about density curves is the mean of a density curve is indicated by u and the standard deviation of a density curve is indicated by Sx.

Is ABC = def if so name the postulate that applies
The triangles do not meet the criteria of any postulate, therefore, they might not be congruent.
What are Congruent Triangles?There are criteria that can be used to show that two triangles are congruent to each other. They are:
ASA postulate: This says that two triangles are congruent if they have two pairs of congruent angles and one pair of included congruent sides.SAS postulate: This says that two triangles are congruent is they have two pairs of congruent sides and one pair of included congruent angles.HL postulate: If both triangles have equal hypotenuses and a pair of congruent corresponding legs, then they are congruent triangles based on this postulate.SSS postulate: both triangles are congruent if they have three pairs of congruent sides.However, two triangles can have three pairs of congruent angles and may not necessary be congruent triangles.
The triangles in the image below shows that the two triangles have three pairs of corresponding congruent angles. This information is not enough to prove they are congruent.

Step-by-step explanation:
Answer:
y = 2x + 3
Step-by-step explanation:
Parallel lines must have the same slope, in the given equation, the slope is 2, so the slope for the parallel line must also be 2, so that eliminates answer choices B and D.
Now to choose between answer choices A or C, you can just plot the given point (-3, -3) into each equation and see which one fits. Answer A seems to be the correct answer.

sorry if it’s blurry but it says Find the midpoint of the segment with endpoints (6,7) and (6,-5)
The x coordinates, 6 and 6, add to 6+6 = 12. Then we cut this in half getting 12/2 = 6.
The x coordinate of the midpoint is 6.
The y coordinates, 7 and -5, add to 7+(-5) = 2. Which cuts in half to get 2/2 = 1.
The y coordinate of the midpoint is 1.
Put together, the midpoint is located at (6,1)

Answer:
x=−3 and y=−1
Step-by-step explanation:
Substitute y=4x+11y=4x+11 into 2x-5y=-12x−5y=−1
-18x-55=-1−18x−55=−1
Solve for x in -18x-55=-1−18x−55=−1.
x=-3
Substitute x=-3x=−3 into y=4x+11y=4x+11.
y=-1
Answer:
28

2x-5(4x+11)=-1
2x-20x+55=-1
-22x+55=-1
-22x+55-55=-1-55
-22x/-22=-56/-22

What is the slope of the line that passes through the points (-5,0) and (7,8)?
Write your answer in simplest form.
Answer:
Step-by-step explanation:
Use the slope formula:
[tex]m = \frac{y2 -y1}{x2 - x1}[/tex]
where m = slope
(-5, 0) -> means x1 = -5. y1 = 0
(7, 8) -> means x2 = 7 , y2 = 8
Substitute these values into the slope formula above and you get:
[tex]m = \frac{y2 -y1}{x2 - x1} = \frac{8-0}{7- (-5)} = \frac{8}{7+5} = \frac{8}{12} = \frac{2}{3}[/tex]
The slope of the line that passes through the points (-5,0) and (7,8) is 2/3
The formula for calculating the slope of a line is expressed as:
[tex]m = \frac{y_2-y_1}{x_2-x_1} \\m=\frac{8-0}{7-(-5)} \\m=\frac{8}{7+5}\\m=\frac{8}12} \\m= \frac{2}{3}\\[/tex]
Hence the slope of the line that passes through the points (-5,0) and (7,8) is 2/3

Paul is making a ball-toss game for his club booth at the fair. He wants to make the circumference of the holes at least 3 inches greater but not more than 4 inches greater than the circumference of the ball. One person suggests that Paul can make the diameter of the hole 1 inch greater than that of the ball. Another suggests the diameter should be 2inches greater. Which suggestion should Paul choose? Explain
Answer:
Paul can make the diameter of the hole 1 inch greater than that of the ballStep-by-step explanation:
we are going to assume a diameter of the hole has 6in
the radius of the ball is 3in
we looking at a range of the hole greater by (3<4)
we know that the circumference of a circle is given as
the circumference of the ball is
C=2πr
C=2*3.142*3
C=18.85in
The circumference of the hole is ( 1 inch greater )
C=2πr
say the diameter is 6in plus 1in = 7in
the radius =3.5in
C=2*3.142*3.5
C=21.99
compare with the ball the difference is 21.99-18.85
=3.14 which is in the range
The circumference of the hole is ( 2inches greater. )
C=2πr
say the diameter is 6in plus 2in = 8in
the radius =4in
C=2*3.142*4
C=25.13in
compare with the ball the difference is 25.13-18.85
=6.28 which is out of the range
