Answer:
There are few kind of statistics: first of all - Mathematiсal statistics. This is quite a mathematical science.
Its applications widely used in many branches of science. First of all (for me) in measurement theory. When used correctly, there is no objection to this science and its methods.
The use in the so-called "social sciences", primarily in sociology, raises many questions: first and foremost - how representative is the "sample"? To what extent does the question asked by the respondent dictate the “correct” (expected) answer? And so on. Of course, this is not a statistic, but mostly a science-like hype, covering up the absence of objective methods.

2) For a negative number, x, is the absolute value of x a positive number or a negative number? Explain.
Answer:
A positive number.
Step-by-step explanation:
Absolute value means that no matter if the number is positive or negative, it will always be positive, e.g. | -4 | would be 4 or | 4 | would also be 4.

Find the perimeter and area of a rectangle of cardboard measuring 11.3 cm by 14.8 cm.
Area of rectangle = Length * Width
Length = 11.3 cmWidth = 14.8 cmArea = 11.3 cm * 14.8 cm
Area = 167.24
PerimeterPerimeter of rectangle = 2 (L + W)
Length = 11.3 cmWidth = 14.8 cmPerimeter = 2 (11.3 cm + 14.8 cm)
Perimeter = 2 (26.1 cm)
Perimeter = 52.2 cm²
Final AnswerArea of rectangle is 167.24 cm²
Perimeter of rectangle is 52.2 cm²
The length of a rectangle is 10 meters more than its width. If the perimeter of the rectangle is 80 meters, find the dimensions of the rectangle
Answer:
Step-by-step explanation:
L = w + 10
w = w
P = 2w + 2L
P = 80 m
2L + 2w = 80 Substitute for L
2(w + 10) + 2w = 80 Remove the brackets
2w + 20 + 2w = 80 Combine on the left
4w + 20 = 80 Subtract 20 from both sides
4w = 80 - 20
4w = 60 Divide by 4
w = 60/4
w = 15
L = 15 + 10 = 25
Check
2*25 + 2*15
50 + 30
80
So this checks

Suppose carpet for a 12ft by 14ft room costs $400 find the cost to carpet a room 48ft by 56ft
Answer:
[tex]\$\ 6400[/tex]
Step-by-step explanation:
1. Approach
The easiest way to solve this problem is to find the area of the first room with the dimensions of (12ft) by (14ft). Then one will divide the cost of carpeting the room by the area of the room, this will yield the price of carpeting per square foot. After finding the price of carpeting per square foot, one will find the area of the second room, with the dimensions of (48ft) by (56ft). Finally, one will multiply the price per square foot of carpeting by the area of the second room to find the price for carpeting the second room.
2. Find the area of the first room
Assume that the first room is a rectangle. the following formula can be used to find the area of a rectangle,
[tex](length)(width)=Area[/tex]
The following are the dimensions of the given room,
[tex]length = 14\\width = 12[/tex]
Substitute into the formula to find the area and simplify to solve,
[tex](length)(width)=Area[/tex]
[tex](14)(12)=Area_1[/tex]
[tex]168=Area_1[/tex]
3. Find the price of carpeting per square foot
To find the price of carpeting per square foot, divide the total price for carpeting the first room by the area of the first room.
[tex]\frac{carpeting\ price_1}{area_1}[/tex]
[tex]=\frac{400}{168}[/tex]
Simplify,
[tex]=\frac{400}{168}[/tex]
[tex]=\frac{50}{21}[/tex]
4. FInd the area of the second room
Assume that the second room is also a rectangle. Use a similar strategy to find the area of this room as used for the area of the first room.
[tex](length)(width)=Area[/tex]
[tex]length = 48\\width = 56[/tex]
Substitute and simplify to sovle,
[tex](length)(width)=Area[/tex]
[tex](48)(56)=Area_2[/tex]
[tex]2688=Area_2[/tex]
5. Find the price for carpeting the room
Multiply the area of the room by the price for carpeting per square foot to find the price for carpeting the second room.
[tex](Area_2)*(carpeting\ price)[/tex]
[tex]2688=Area_2[/tex]
[tex]\frac{50}{21}=carpeting\ price[/tex]
[tex](Area_2)*(carpeting\ price)[/tex]
[tex]=(2688)*(\frac{50}{21})[/tex]
Simplify to solve,
[tex]=(2688)*(\frac{50}{21})[/tex]
[tex]=(2688)*(\frac{50}{21})[/tex]
[tex]=6400[/tex]

lim x-> 0^+ (1+sin7x)^8/x
If you mean
[tex]\displaystyle \lim_{x\to0^+} \frac{(1+\sin(7x))^8}x[/tex]
then the limit doesn't exist, since 1 + sin(7x) approaches 1 while the denominator approaches 0.
However, if instead you mean
[tex]\displaystyle \lim_{x\to0^+}(1+\sin(7x))^{8/x}[/tex]
rewrite the limand as
[tex](1+\sin(7x))^{8/x} = \exp\left(\ln(1+\sin(7x))^{8/x}\right) \\\\ = \exp\left(\dfrac{8\ln(1+\sin(7x))}x\right) \\\\ =\exp\left(\dfrac{\ln(1+\sin(7x))}x\right)^8[/tex]
The exponential function is continuous at 0, so we can pass the limit through it:
[tex]\displaystyle\lim_{x\to0^+}\exp\left(\dfrac{\ln(1+\sin(7x))}x\right)^8 = \exp\left(\lim_{x\to0^+}\dfrac{\ln(1+\sin(7x))}x\right)^8[/tex]
The remaining limit takes the indeterminate form 0/0, since ln(1 + sin(7x)) approaches ln(1) = 0, and so does x in the denominator. Apply L'Hopital's rule:
[tex]\displaystyle\exp\left(\lim_{x\to0^+}\dfrac{7\cos(7x)}{1+\sin(7x)}\right)^8 = \exp\left(7\right)^8 = \left(e^7\right)^8 = \boxed{e^{56}}[/tex]

Answer: y = 8, x =5
Step-by-step explanation:
x+y = 13
or, x = 13-y
so
2x - y = 2
substituting x's value
2(13-y)-y = 2
or, 26-2y-y = 2
or, 26-3y=2
or, 26-2 = 3y
or, 24 = 3y
so, y = 8
now
x = 13-y
so, x = 13-8 = 5

Please help!!
Mark brainliest!!!
Formula-
If a set has “n” elements, then the number of subset of the given set is 2n and the number of proper subsets of the given subset is given by 2n-1. Consider an example, If set A has the elements, A = {a, b}, then the proper subset of the given subset are { }, {a}, and {b}
Symbol that can be used-
The symbol "⊆" means "is a subset of". The symbol "⊂" means "is a proper subset of".
