Answer:
Representative.
Step-by-step explanation:
In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
A representative sample has characteristics similar to those of the entire population and, therefore, can be used to draw a conclusion about the (general) population. Thus, it is considered typically to be a subset of population and can be used to accurately make conclusions and reflect the characteristics of the larger sample (population).
9c+1=10 i do not know the answer to this problem
Answer: To figure out the answer, you have to find c, c equals 0 because adding anything from 9 + 1 equaling 0 will get you above the answer, 10. so, 9c + 1 = 10, now lets change the equation to 9c(0) + 1 = 10, c equaling zero would make the most sense because if c equals 0 then you will get 10, the answer.

Which of there polynomials could have (x-2) as a factor?
a(x) = 6x² - 7x - 5
b(x) = 3x² + 15x - 42
c(x) = 2x³ + 13x² + 16x + 5
d(x) = 3x³ - 2x² - 15x + 14
e(x) = 8x⁴ - 41x³ - 18x² + 101x + 70
f(x) = x⁴ + 5x³ - 27x² - 101x - 70
Answer:
x-2 is a factor of following polynomials:
b(x) = 3x² + 15x - 42d(x) = 3x³ - 2x² - 15x + 14 e(x) = 8x⁴ - 41x³ - 18x² + 101x + 70Step-by-step explanation:
In order to check that which polynomials might have x-2 as a factor, we will put
x-2 = 0 => x = 2 in each polynomial, if the value of polynomial on 2 is zero then x-2 is a factor otherwise not.
So,
a(x) = 6x² - 7x - 5
Putting x = 2
[tex]a(2) = 6(2)^2-7(2)-5\\= 6(4)-14-5\\=24-14-5\\=24-19\\=5 \neq 0[/tex]
b(x) = 3x² + 15x - 42
[tex]b(2) = 3(2)^2 + 15(2) - 42\\=3(4)+30-42\\=12+30-42\\=42-42 = 0[/tex]
c(x) = 2x³ + 13x² + 16x + 5
[tex]c(2) = 2(2)^3 + 13(2)^2 + 16(2) + 5\\=2(8)+13(4)+32+5\\=16+52+32+5\\=105 \neq 0[/tex]
d(x) = 3x³ - 2x² - 15x + 14
[tex]d(2) = 3(2)^3 - 2(2)^2 - 15(2) + 14\\= 3(8)-2(4)-30+14\\=24-8-30+14\\=38-38 = 0[/tex]
e(x) = 8x⁴ - 41x³ - 18x² + 101x + 70
[tex]e(2) = 8(2)^4 - 41(2)^3 - 18(2)^2 + 101(2) + 70\\= 8(16)-41(8)-18(4)+202+70\\=128-328-72+202+70\\=0[/tex]
[tex]f(2) = (2)^4 + 5(2)^3 - 27(2)^2 - 101(2) - 70\\=16+5(8)-27(4)-202-70\\=16+40-108-202-70\\=-324 \neq 0[/tex]
Hence,
x-2 is a factor of following polynomials:
b(x) = 3x² + 15x - 42d(x) = 3x³ - 2x² - 15x + 14 e(x) = 8x⁴ - 41x³ - 18x² + 101x + 7012 divided by 12 x 34 x 5

Elijah buys P pounds of bananas for 60 cents per pound. He pays the clerk with a twenty-dollar bill. The clerk subtracts the total cost of the bananas from the twenty dollar bill to determine the amount of change to give Elijah.
Answer: (20-0.6P)
Step-by-step explanation:
Given: Elijah buys P pounds of bananas for 60 cents per pound.
Since 1 dollar = 100 cents
Then, 60 cents = [tex]\$\dfrac{60}{100}=\$0.6[/tex]
Cost of P pounds of bananas = Cost per pound x P
= $0.6 P
He pays the clerk with a twenty-dollar bill.
Change he will get = $ 20 - Cost of P pounds of bananas
= $ (20-0.6P)
Hence, the expression of the change Elijah will get = (20-0.6P)

Answer:
15 inches.
Step-by-step explanation:
Since we know its a square, we know that the side lengths are all equal. Knowing this, we know that we could find the area by taking a side length and squaring it. So we can take the square root of 219 to find the side length:
√219 = 14.79864859 ≈ 15
Therefore, the side lengths of the sign are about 15 inches.

180 = 124 + x >> subtract 124 from both sides
56 = x

plzzz help .Which point is included in the graph of the ceiling function f(x) = [x]?
Answer: Choice C. (-3.5, -3)
========================================================
Explanation:
Draw a vertical number line. Make sure to plot the points -3 and -4 on this number line. We'll have -4 below -3. In between these values is -3.5
The ceiling function brings the point -3.5 up to -3. Think of an elevator that visits each floor of a skyscraper. Each floor being a positive or negative whole number on this number line. So when x = -3.5, this means f(x) = -3. This points to choice C being the answer.
As another example, if x = 5.7, then f(x) = 6. Yet another example would be x = 2.008 leads to f(x) = 3. We always move up to the closest integer.

What is a system of equations?A finite collection of equations for which we searched for common solutions is referred to in mathematics as a system of equations, sometimes known as a set of simultaneous equations or an equation system. Similar to single equations, a system of equations can be categorized.
A linear equation can only have one unique solution, which is a location at which the LHS and RHS of the equation are equal. There is only ever one solution to a linear equation with one variable.
y = 5x - 1
y = 3x + 7
5x - 1 = 3x + 7
2x = 8
x = 4
y = 19
Therefore, there will be one unique solution of the equation y = 5x - 1 and y = 3x + 7.

if x+y=10 and x-y=6 what is this value of x cube - y cube
Answer:
x cubed minus y cubed is equal to 504
Step-by-step explanation:
First we need to know what the values of x and y are. We can do this pretty easily, by just solving both equations for x, and equating them to each other:
With the first:
x + y = 10
x = 10 - y
And with the other
x - y = 6
x = 6 + y
Now that we have two definitions of x, we can say that the expressions are equal, and solve for y:
10 - y = 6 + y
10 - 6 = y + y
4 = 2y
y = 2
And now that we know what y is, we can find x:
x = 10 - y
x = 10 - 2
x = 8
So x is equal to eight. We can check our answer by plugging x into the other equation and seeing if we get the same value for y:
x - y = 6
8 - y = 6
-y = 6 - 8
-y = -2
y = 2
So we know we solved that correctly.
Now if we cube each number, eight cubed is equal to 512, and 2 cubed is equal to 8. If we subtract the latter from the former we get 504.
so x cubed minus y cubed is equal to 504
