As the number of surveys conducted increases, the average of the sample means approaches the population mean.
Step-by-step explanation:
Plato
The average of the sample mean from the given data values in the table is gotten as; 14.98
How to find the average of mean?
When finding the average, we need to sum up all the given data and then divide by the total number of data.
The given data values are; 15.09, 14.45, 14.91, 15.09, 14.91, 15.82, 14.36, 15.55, 14.36, 15.27.
The sum of these given data is;
15.09 + 14.45 + 14.91 + 15.09 + 14.91 + 15.82 + 14.36 + 15.55 + 14.36 + 15.27 = 149.81
Thus;
Average of sample mean = 149.81/10
Average = 14.98

Answer: y = -2x + 6
Slope-intercept form: y = mx + b, where m = slope and b = y-int
m = -2
(-1, 8) --> -1 = x₁, 8 = y₁
Based on the slope and given point, use oint-slope form, y - y₁ = m(x - x₁), to find the slope-intercept equation:
y - 8 = -2[x -(-1)]
y - 8 = -2(x + 1)
y - 8 = -2x - 2
y = -2x + 6
The sun causes changes to things on Earth. Think of an object you have observed before and after it was left out in the sun. Describe how it changed.
Answers
Answer: well i have put things like leather and it shrunk while it was out in the sun
Step-by-step explanation:
We want to study how the Sun affects things on Earth, I will give you two examples.
First, we know that the Sun radiates electromagnetic energy.
So if you left something in the Sun, its temperature will increase (as it receives the radiation) but more things can happen.
The first example can be a plant, that if it was inside at first, and then you put it in the sun for a while, you will for sure see a change in the plant contexture. This happens because the Sun gives energy to the plant (or the plant utilizes the radiation that comes from the Sun as energy).
Another example (and another phenomenon) can be a black shirt that is left in the Sun for several hours. The radiation (UV radiation particularly) affects the dye in the shirt by a process called photodegradation. Thus, the color of the shirt fades away.
So these are just two different examples of how the Sun affects things on Earth.

A tire on a vehicle has a diameter of 30in. As it moves down the
road it makes 50 full revolution. What is the approximate distance
it traveled?
Answers
Answer:
94.25 in

In one revolution, the tire moves a distance equal to its circumference. If the diameter is 30 in, the radius is half of that, 15 in. Circumference is 2 pi times the radius:

Although being a military defeat, the Tet Offensive was a stunning propaganda win for communists. In fact, it is frequently regarded for changing the tide of the war in their favour.
As Viet Cong rebels invaded rural areas previously held by the South Vietnamese government, the South Vietnamese began to lose authority.
Despite tremendous deaths, North Vietnam secured a strategic triumph with the Tet Offensive, which represented a watershed moment in the Vietnam War and the start of the protracted, agonising American withdrawal from the region.

A regular polygon is a shape with sides that all have equal lengths and angles that all have equal measures. If each exterior angle of a certain regular polygon measures 24o, what is the interior angle sum for this polygon?
Answers
Answer:
2340
Step-by-step explanation:
360/24 =15whichis number of sides
180(15-2)=2340
Answer:
Exterior Angle of 24º means Interior Angle of 156º
Interior Angle = 180 -Exterior Angle
Number of sides = 360 / (180 - ONE Interior Angle)
Number of sides = 360 / (180 - 156º)
Number of sides = 360 / 24
Number of Sides = 15

I like dogs but this question is a hard one.
Answers
Answer:
Work below
Step-by-step explanation:
49 total dogs.
36 more small dogs.
13 big dogs.
lol just realized today's school has sh*t wording and this question can be taken TWO ways. 36 more as in, 36 more dogs in total or 36 more small dogs than large dogs adding the amount of large dogs with this. this gives us 49.
the only way to get the x value (large dogs) and add this on top of the 36 (small dogs) and get 49 is to do 6.5 + 42.5 (36 + 6.5) this gives us 49.
Thanks guy in the comments for giving the second response, after some thinking i realized that i could also read it that way.
F** k today's hw and their wording
Answer:
6.5 Large Dogs
42.5 Small Dogs
Step-by-step explanation:
You simply do not have enough love for dogs to solve the question.
Luckily I have an extremely high affection for dogs so I can help.
S = amount of small dogs
L = amount of large dogs
S + L = 49
S = 36 + L
plug the second equation into the correct variable of the first equation so:
(36+L) + L = 49
36 +2L = 49
2L = 49-36
L = 6.5 *this doesn't make sense*
S = 42.5 *this also doesn't make sense*

Step-by-step explanation:
X 0 1 2 3 4
P(X) 0.1 0.2 0.4 0.2 0,1
a) Find the probability of 1 tire with low air pressure P (1) :
From probability distribution table Given :
P(1) = 0.2
b) Find the probability of more than 2 tires having low air pressure P (more than 2) =
P(x > 2) = p(3) + p(4)
P(x > 2) = 0.2 + 0.1 = 0.3
c) P (all 4 tires)
From the table :
P(x = 4) = 0.1
d) Compute the expected number of tires with low air pressure.
E(X) = Σx * p(x)
E(x) = (0*0.1) + (1*0.2) + (2*0.4) + (3*0.2) + (4*0.1) = 2
