Answer: D: A random sample of 1000 people from each of the 50 states
Step-by-step explanation:
So to get the best results we want to eliminate as many sources of bias that we can so lets go through the answers
A: A: A random sample of 1000 people from 10 local clothing stores. This is bias because if we choose from people shopping at a store they might like to shop more than usual
B: A random sample of 1000 people from his city. This can't possibly represent all the people in the U.S. because the sample is only from his city so we can't choose this answer
C: A random sample of people from his state. Again this doesn't represent the U.S. and also we don't have a number for the sample size
D. D: A random sample of 1000 people from each of the 50 states. This answer is good because we have a sample size, its random, and it represents the 50 states

Step-by-step explanation:
En la ciudad la temperatura en la noche fue de 2 grados sobre cero y en la madrugada llegó a 12 grados bajo cero. ¿Qué diferencia de temperaturas hubo en esas horas?
Responder:
La temperatura bajó 12 °
Explicación paso a paso:
Dado que:
Temperatura en la noche = + 2 ° (2
Temperatura de la mañana = - 12 (12 ° bajo cero).
La diferencia de temperatura entre la noche y la madrugada:
Temperatura nocturna - temperatura por la mañana temprano
2 - (-12)
2 + 12 = 14
Hay una diferencia de temperatura de 12 °. La temperatura bajó 12 ° entre la noche y la madrugada.

find the slope of the line that passes through (-6, -2) and (-7, -2)
Answer:
[tex]0[/tex]
Step-by-step explanation:
We could use the Slope Formula to find the answer, but there's an easier way of doing it. Notice that the y-coordinates of both points are the same. This means that the line that passes through these points is horizontal, which makes our answer [tex]0[/tex] because all horizontal lines have a slope of [tex]0[/tex].
All horizontal lines have a slope of [tex]0[/tex] because the value of y never changes as the value of x changes, so if we were to input any two points on a horizontal line into the Slope Formula, our numerator would be [tex]0[/tex] (because anything subtracted from itself is [tex]0[/tex]), leaving us with a result of [tex]0[/tex] regardless of the denominator since [tex]0[/tex] divided by anything is [tex]0[/tex]. Hope this helps!

Step-by-step explanation:
find the measure of VU
The measure of VU is 16 units
The given parameters are:
[tex]OV = 7x + 2[/tex]
[tex]VU = 3x + 10[/tex]
Given that, lengths OV and VU are congruent, we have:
[tex]OV =VU[/tex]
Substitute values for OV and VU
[tex]7x +2 =3x + 10[/tex]
Collect like terms
[tex]7x -3x = 10 -2[/tex]
Evaluate like terms
[tex]4x = 8[/tex]
Divide both sides by 4
[tex]x = 2[/tex]
Substitute 2 for x in [tex]VU = 3x + 10[/tex]
[tex]VU = 3 \times 2 + 10[/tex]
[tex]VU = 6 + 10[/tex]
Evaluate like terms
[tex]VU = 16[/tex]
Hence, the measure of VU is 16 units

The graph of the parent function f(x) = xº is translated to form the graph of g(x) = (x - 4) 3 - 7. The point (0, 0) on the
graph of f) corresponds to which point on the graph of g(x)?
Answer: The point (0, 0) corresponds to the point (4, -7)
Step-by-step explanation:
We have the function f(x) = x^3
And we transform this to get:
g(x) = (x - 4)^3 - 7
Here we have a vertical translation and a horizontal shift, let's define these two shifts:
Vertical shift.
If we have a function f(x), a vertical shift of N units is written as:
g(x) = f(x) + N
This will move the graph of f(x) up or down a distance of N units.
if N is positive, then the shift is upwards
if N is negative, then the shift is downwards.
Horizontal shift.
If we have a function f(x), a horizontal shift of N units is written as:
g(x) = f(x + N)
This will move the graph of f(x) to the right or left a distance of N units.
if N is positive, then the shift is to the left
if N is negative, then the shift is to the right.
Then if we start with f(x), g(x) is a translation of 7 units down and 4 units to the right.
This means that any point (x, y) that belongs to the graph of f(x), after the transformation will be (x + 4, y - 7)
Then the point (0, 0) of the original function corresponds to the point (0 + 4, 0 - 7) = (4, - 7) of the function g(x)
We can check this, we need to evaluate the function g(x) in x = 4
g(4) = (4 - 4)^3 - 7= 0 - 7 = -7
g(4) = -7
Then the point (4, -7) belongs to the graph of g(x).

Answer:
Michelle.
Step-by-step explanation:
D'Andre's Bank Account:
Remember to find the line, you need to use the formula y=mx+b. The m stands for slope while the b is the y-intercept. For D'Andre's y-intercept we can see that it's 0 and the slope is 2 (you can find it by doing rise/run). His equation is y = 2x.
To find how long it'll take him to get to $500, plug 500 into y: 500 = 2x
Divide by 2 on both sides: 250 = x
It'll take D'Andre 250 months to reach $500.
Fiona's Bank Account:
Unlike D'Andre's graph, she already has the equation, except that it isn't in the easiest form. To get it back to what it was, add 12x to the other side of the equation:
y - 12x = 100**
+ 12x = +12x
y = 12x + 100
**Just in case you didn't know, the 100 just means that's how much money she had started out with.
Plug in 500 for y: 500 = 12x +100
Subtract 100 from both sides: 400 = 12x
Divide by 12 to get x alone: 100/3 = x
It'll take Fiona about 33 months to reach $500.
Sam's Bank Account:
Sam has a table for his account, so we need to subtract some of the y coordinates to find his slope. Using 60 and 45 difference, we get 15. Looking at the table I can tell that is the slope because 15 is continually being added. To find his y - intercept, we need to look when his x coordinates was a 0. Therefore, his y-intercept is 60. His equation is y = 15x + 60
Plug in 500 for y: 500 = 15x + 60
Subtract 60 from both sides: 440 = 15x
Divide by 15 to get x by itself: 88/3 = x
It'll take Sam about 29 months to reach $500.
Michelle's Bank Account:
Last we have Michelle. Since she started with 25 dollars, that'll be her y-intercept. It also says that she is depositing 25 dollars per month, meaning 25 is her slope. Her equation should look like y = 25x + 25.
Plug in 500 for y: 500 = 25x + 25
Subtract 25 from both sides: 475 = 25x
Divide 25 from both sides to get x isolated: x = 19
It'll take Michelle 19 months to get $500.
So, in the end, Michelle will reach $500 dollars first.

Given:
The graph of a line segment.
To find:
The distance between the pair of points.
Solution:
From the given graph it is clear that the end points of the line segment are (-3,-1) and (-2,-3).
The distance between these two points is:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]d=\sqrt{(-2-(-3))^2+(-3-(-1))^2}[/tex]
[tex]d=\sqrt{(-2+3)^2+(-3+1)^2}[/tex]
[tex]d=\sqrt{(1)^2+(-2)^2}[/tex]
On further simplification, we get
[tex]d=\sqrt{1+4}[/tex]
[tex]d=\sqrt{5}[/tex]
[tex]d=2.236067[/tex]
[tex]d\approx 2.2[/tex]
Therefore, the distance between the pair of point is about 2.2 units.

Answer:
I believe that it is A, C and G
Step-by-step explanation:
for A(7×2=14)+4=18 is equivalent to (3×2=6)+5+(4×2=8)-1=18
For C it is right because with the values being the same at x value at first the second equation would have one extra but it does subtract that.
For G check c :)
