Answer:
a part of the population that represents the entire population
Step-by-step explanation:
A sample simply refers to a smaller group of observation usually drawn from a larger group or a collection of the total possible observation that fits a particular or specific characteristic(population). This smaller group or subset of observation is usually chosen to be representative of the larger group of population. Representative Samples are usually obtained by drawing at random from the population and are very important where using the entire population for a study seems impossible or very expensive or intensive.

Simplify, give answer in exponential form: 3^9 x 3^4
Answer:
In exponential form, the correct answer is [tex]3^{13}[/tex].
Step-by-step explanation:
When you're multiplying exponents with the same base together, you keep the base the same and add the powers of the two exponents together. In this case, [tex]3^{9} * 3^{4} = 3^{9+4} = 3^{13}[/tex].

Find a polynomial f(x) of degree 3 with real coefficients and the following zeros. -2,- 2+i.
Answer:
f(x) = x^3 + 2x^2 + x + 2
Step-by-step explanation:
If -2 + i is a zero, then -2 - i must also be a zero.
These zeros are -2, -2 + i and -2 - i, and the corresponding factors of the polynomail f(x) are (x + 2), (x + 2 - i) and (x + 2 + i).
(x + 2 - i) and (x + 2 + i) multiplied together becomes x^2 + 1.
Multiplying this result by the 3rd and last factor, (x + 2), we get
(x^2 + 1)(x + 2) = x^3 + 2x^2 + x + 2
Check, using synthetic division. What are the factors of x^3 + 2x^2 + x + 2?
-2 / 1 2 1 2
-2 -2 -2
-----------------------
1 0 -1 0 Since the remainder is zero, we know that
(x + 2) is a factor and -2 is a root.

Answer:
x=70
Step-by-step explanation:
it's 70 because 50 and 20 is proportional to x
Answer:
70
Step-by-step explanation:
The angles <FEB and <AEG are vertical angles. This means they have the same measurement. To find <FEB add the two angles <FED and <DEB together. This equals 70; therefore, x must also be equal to 70 degrees.

FalseTrueTrueFalseTrueFalse===============================================
Explanations:
If we can write a number as a ratio (or fraction) of two whole numbers, then that number is considered rational. The denominator can never be 0. In the case of 6/4, this is a rational number. Therefore, the statement "6/4 is irrational" is false. This is a true statement. We cannot write sqrt(2) as a fraction of two integers. The proof of this is fairly lengthy, but one way is to use a proof by contradiction to show that sqrt(2) = a/b is impossible. Since we cannot make sqrt(2) into a ratio of two integers, we consider it irrational.This is a true statement. Any terminating decimal is always rational. In this case, 1.3 = 13/10.This is false. Any repeating decimal can be converted to a fraction through a bit of work. It turns out that 17.979797... = 1780/99 which makes the value to be rational.Any integer is rational. We can write the integer over 1. So something like -16 is the same as -16/1, showing how it is rational. So that's why this statement is true.This statement is false because we found true statements earlier.Mary wants to make bouquets of roses. She has 32 lavender roses, 48 pink roses and 64 white roses. She wants each bouquet to have the same number of flowers of each color. What is the maximum number of bouquets she can make? Choose only ONE best answer. А 8 B 16 C 24 D 32 E 192
Answer:

Write an equation to represent the cost at each studio (2 points)
Solve the system (2 points)
Write the solution as a point (x, y) (2 points)
Answer:
Cost A = 125 + 50t
Cost B = 200 + 25t
Step-by-step explanation:
Answer:
Cost A = 125 + 50t
Cost B = 200 + 25t

mr.rai sells a watch set for rs2,035 at 10% profit . how much money has he paid to buy the watch also find profit amount
Answer:
paid to buy = 1850
profit = 10%
Step-by-step explanation:
2035 = 110%
1% ~ = 18.5
100% = 1850
2035 - 1850 = 185
185 / 1850 * 100 = 10% profit
which of the expressions have a value of 2?
Answer:
The answers are B and E
Step-by-step explanation:
The square root of 4 is 2.
The cube root of 8 is 2.
A is wrong because its value is 4.
C is wrong because its value is 4.
D is wrong because the square root of 8 isn't whole.
Answer:
E. √4
B. ³√8
Step-by-step explanation:
You can find this simply by putting it into a calculator if you have access to one. Just type √ and 4. If you don't have a calculator, you can just use the knowledge that 2 × 2 = 4, hence why it's the square root of 4 :)
You can also determine that B is correct by doing 2 to the power of 3.
2³ = 8, so you know that B is correct too.
Find the measure of angle H
Answer:
80
Step-by-step explanation:
All triangle angles add up to 180 so:
4x - 20 + 2x + 2x = 180
8x - 20 = 180
8x = 200
x = 25
<H:
4x - 20
4(25) - 20
100 - 20
80
