The test scores of a geometry class are given below. 90, 75, 72, 88, 85 The teacher wants to find the variance for the class population. What is the value of the numerator of the calculation of the variance? Variance: sigma squared = StartFraction (x 1 minus mu) squared (x 2 minus mu) squared ellipsis (x N minus mu) squared Over N EndFraction -160 -6 16 258.
The value of the numerator of the calculation of the variance is 258, the correct option is D.
Given
The test scores of a geometry class are given below. 90, 75, 72, 88, 85.
What is a variance?Variance is the expected value of the squared variation of a random variable from its mean value, in probability and statistics.
The mean of the test scores of a geometry class is;
[tex]\rm Mean = \dfrac{90+75+72+88+85}{5}\\\\ Mean =\dfrac{ 410}{5}\\\\Mean =82[/tex]
The variance is given by;
[tex]\rm Variance =\dfrac{(90 - 82)^2 + (75 - 82)^2 + (72 - 82)^2 + (88 - 82)^2 + (85 - 82)^2}{5}\\\\Variance = \dfrac{8^2+7^2+(-10)^2+6^2+3^2}{5}\\\\Variance=\dfrac{64+49+100+36+9}{5}\\\\Variance = \dfrac{258}{5}[/tex]
Hence, the value of the numerator of the calculation of the variance is 258.

What is the slope
So technically this is the graph I picked a random answer but I dibt get how the slope is 4 can you guys please explain
the answer I got was 4
Answer:
4
Step-by-step explanation:
We can use the y-y/x-x formula.
We need to find two points that are a whole number.
(0,10) -- 0 is the x coordinate, 10 is the y coordinate.
(20,90) -- 20 is the x coordinate, 90 is the y coordinate.
10-90 = -80
0-20 = -20
-80/-20 as a whole number is 4.
The slope is 4.

Dwayne buys a new smartphone for $719.76. He agrees to pay for it monthly, with 24 equal payments.
How much does he pay each month for the smartphone?
Answer:
$29.99
Step-by-step explanation:
24 equal payments represent 24 months (as it is paid monthly), therefore, you divide by 24 to get only 1 month of the payment
719.76/24

Answer:
Step-by-step explanation:
rise / run is another way of expressing the tangent.
So when you are told that the rise over run is 35% you mean the rise is 35% of the run.
Another way of expressing this is by saying Tan(theta) = 0.35
theta = tan-1(0.35)
theta = 19.29 degrees.
The answer is A. You can reason this out. 19 degrees is the smallest answer. If it was any larger, do you think an 18 wheeler would be able to make the grade? Likely not.
How do I solve this, it's not 10
Answer:
26.7
Step-by-step explanation:
This is the answer because 26.7/20 = (16+26.7)/32
When two triangles are similar, it means their sides are also proportional. The reason why it is not ten is because you need to add 10 to 16 to the large triangle as well, which no longer makes it proportional.
To solve, you create a formula.
(16+x)/32=x/20
Multiply both sides by 32 to get rid of the 32 in the left side.
16+x=32x/20
Multiply both sides by 20 to get rid of the 20 right side.
320+20x=32x
-20x on both sides to get all the variables on one side and all the nukbers on the other.
320=12x
Divide both sides by 12 to get x by itself
x=26.66667
Rule: subtract 2 from x to get y
Answer:
x-2=y
Step-by-step explanation:
I have written the equation for the statement.

teh face of a circular game token has an area of 10pi cm to the second power. what is the diameter of the coin token. round to the nearest hundredth of a centimeter
Answer:
6.32 cm
Step-by-step explanation:
Area of a circle = [tex]\pi r^2[/tex] (where r is the radius)
Given area = [tex]10\pi[/tex] cm²
⇒ [tex]10\pi=\pi r^2[/tex]
[tex]\implies 10=r^2[/tex]
[tex]\implies r=\sqrt{10}[/tex]
Diameter = 2r (where r is the radius)
[tex]\implies d=2r=2\sqrt{10}=6.32[/tex] cm (nearest hundredth)
Area of a circle = [tex]πr²[/tex]
Given area = [tex]10π cm²[/tex]
[tex]\bold\red{ ⇒} 10π = πr²[/tex]
[tex]\bold\red{⇒ } 10 = r²[/tex]
[tex]\bold\red{⇒ } r = \sqrt{10}[/tex]

Trisha and Yoshi are at the start of
a trail. Trisha walks 500 feet
before Yoshi starts. Trisha walks
350 feet per minute, and Yoshi
walks 430 feet per minute.
Answer:
If youre asking how long it will take for Yoshi to catch up look below
Step-by-step explanation:
Yoshi walk 80 feet per minute faster than Trisha
If Trisha walks for 5 minutes she would have walked 2250 feet
If Yoshi also walks for 5 minutes he would have walked 2150 feet
Now this is already pretty close so lets check for 7 minutes
If Trisha walks 7 minutes she would have walked 2950 feet
if Yoshi walks 7 minutes he would have walked he would have walked 3010 feet
Now this is really close but now yoshi is ahead.. so lets go down to 6.85 feet
If Yoshi walks 6.85 minutes he would have walked 2945.5 feet
this is still a LITTLE to low so lets do 6.86
If yoshi walks 6.86 minutes he would have walked 2949.8
Rounding up he would have caught up by now
so it would take Yoshi 6.86 minutes to catch up
I really really really really need help with this question
Answer:
When rotating any polygon 90 degrees, each vertice/point of the polygon should be changed from (x, y) to (y, -x). Because of this, E(-7, -4) should be E'(-4, 7), F(-2, -1) should be F'(-1, 2), and G(-5, -8) should be G'(-8, 5) after the rotation.
Step-by-step explanation:
Like I explained above, when rotating a shape 90 degrees clockwise on a plane, the points change from (x, y) to (y, -x). The student changed each point from (x, y) to (-y, x), which is a 90 degree counterclockwise rotation. That is why the student is incorrect.
I hoped this helped! Sorry, I am terrible at explaining things. :)

3x + 2y = 6y>x
y = 1.5 , x= 1
