Applying statistical concepts, it is found that the values are:
p = -11.37q = 81When a constant is added to each data in a variable:
The mean is incremented by this constant.The variance remains constant.When a constant is multiplied to each data in a variable:
The mean is multiplied by this constant.The variance is multiplied by the square of this constantHence, mean of 12, added with p and multiplied with q, for a mean of 51:
[tex](12 + p)q = 51[/tex]
Variance of 84, after the operations, 756:
[tex]84\sqrt{q} =756[/tex]
[tex]\sqrt{q} = \frac{756}{84}[/tex]
[tex]\sqrt{q} = 9[/tex]
[tex](\sqrt{q})^2 = 9^2[/tex]
[tex]q = 81[/tex]
For p:
[tex](12 + p)q = 51[/tex]
[tex](12 + p)81 = 51[/tex]
[tex]12 + p = \frac{51}{81}[/tex]
[tex]12 + p = 0.63[/tex]

Find the m∠NMO. Show your work in the scratchpad.
An isosceles triangle is one which has two equal sides and angles. Therefore, the measure of <NMO required in the given question is [tex]20^{o}[/tex].
An isosceles triangle is a type of triangle which has two equal sides, thus angles.
So that comparing the triangles in the given question, we have:
i. ΔNMQ, ΔMPQ, ΔOPM, and ΔNMO are all isosceles triangles.
Thus;
<MQN = <MNQ = [tex]60^{o}[/tex] (isosceles triangle base angle property)
So that;
<QMN = [tex]180^{o}[/tex] - (<MQN + <MNQ)
= [tex]180^{o}[/tex] - [tex]120^{o}[/tex]
<QMN = [tex]60^{o}[/tex]
ii. In triangle MOP, we have;
<MPO = <MOP = [tex]80^{o}[/tex] (base angle property of isosceles triangle)
Then,
<PMO = [tex]180^{o}[/tex] - ([tex]80^{o}[/tex] +
= [tex]180^{o}[/tex] - [tex]160^{o}[/tex])
<PMO = [tex]20^{o}[/tex]
But,
<QMP + <NMO = ([tex]60^{o}[/tex] - [tex]20^{o}[/tex])
= [tex]40^{o}[/tex]
Since <QMP = <NMO, then;
m<NMO = [tex]\frac{40^{o} }{2}[/tex]
= [tex]20^{o}[/tex]
Thus, the measure of <NMO is [tex]20^{o}[/tex].

4 Zahara rides with her dad to her grandmother's house. They travel 159 miles
in 3 hours. Her uncle, Jorge, drives there separately from his home.
a. At what speed does Zahara's dad drive, in miles per hour?
Based on the distance they covered in the time they did, we can infer that Zahara's dad was driving at 53 miles per hour.
To find the speed, the following formula is used:
= Distance / Time
They travelled 159 miles in 3 hours.
Distance = 159 miles
Time = 3 hours
The speed must be:
= 159/3
= 53 miles per hour
In conclusion, he was going at 53 miles per hour.

What is the value of x in the equation:
−416x=−115
What is the equation of the line that has a slope of -4 and passes through (2, -3)
Answer:
y+3 = -4(x-2)
Step-by-step explanation:
We can use point slope form since we are given a point on the line and a slope,
Point slope form is
(y-y1) = m(x-x1) where m is the slope and (x1,y1) is a point on the line
(y- -3) = -4(x-2)
y+3 = -4(x-2)

Answer: 21
Step-by-step explanation:
To find the missing number you set the two equations as a proportion:
[tex]\frac{7}{9} = \frac{x}{27}[/tex]
To solve for x we cross multiply:
27 × 7 = 189
9 × x = 9x
Set up an equation:
9x = 189
Divide both sides by 9:

We want to write an function that relates the number of blocks south of school that she is to the number of minutes that she has been walking.
The function is: y = (1 block/minute)*x + 8 blocks
A general linear function is:
y = a*x + b
where a is the slope and b is the y-intercept.
First, we do know that she lives 8 blocks south of her school, so the y-intercept of the linear function will be 8 blocks (the point where she starts).
Now we know that her friend lives farther south, so she moves south, at a velocity of 1 block per minute.
Then the linear function is:
y = (1 block/minute)*x + 8 blocks
