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.

Write an explicit formula for
An
, the nth
term of the sequence 36, 46, 56, ....
Answer:
[tex]a_{n}[/tex] = 10n + 26
Step-by-step explanation:
[tex]a_{n} = a_{1} + (n - 1)d[/tex]
In your problem d = 46 - 36 = 10 and [tex]a_{1} = 36[/tex]
So, [tex]a_{n}[/tex] = 36 + (n - 1)10
= 36 + 10n - 10
= 10n + 26
T = 4v + 3
(a)
(b) Make V the subject of the formula T = 4v + 3
The equation T = 4v + 3 is solved for v will be written as v = (T - 3) / 4.
What is the solution to the equation?The possible value of the variables that satisfy the equation which is known as the solution of the equation.
The equation is written below.
T = 4v + 3
The degree of the equation is one. Then the equation is given a linear equation.
Solve the equation for v, then we have
T = 4v + 3
Subtract 3 from both sides, then we have
T - 3 = 4v
Divide the equation by 4 into both sides, then we have
v = (T - 3) / 4
The equation T = 4v + 3 is solved for v will be written as v = (T - 3) / 4.

Graph the line with the given slope that passes through the given point
Slope=2;(-1,4)
Answer:
BStep-by-step explanation:
Point (-1, 4) it's point where x-coordinate is -1 and y-coordinate is 4
Graph in B is the only one passing through (-1, 4)
The equation of the line is y = 2x + 6. The graph is represented by B.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that the slope of the line is 2 and the point through which it is passing is (-1,4).
The equation of the line will be calculated as,
y = mx + c
y = 2x + c
4 = -2 + c
c = 6
The equation will be written as,
y =2x + 6
The graph of the line is attached with the answer below.

Angle sum property of triangle states that the sum of interior angles of a triangle is 180°
We need to prove angle sum property.
What is angle sum property?
The sum of interior angles of a triangle is 180 degrees
Consider a ∆ABC, as shown in the figure below. To prove the above property of triangles, draw a line PQ parallel to the side BC of the given triangle
Since PQ is a straight line, it can be concluded that:
∠PAB + ∠BAC + ∠QAC = 180° ………(1)
Since PQ||BC and AB, AC are transversals,
Therefore, ∠QAC = ∠ACB (a pair of alternate angle)
Also, ∠PAB = ∠CBA (a pair of alternate angle)
Substituting the value of ∠QAC and ∠PAB in equation (1),
∠ACB + ∠BAC + ∠CBA= 180°
Thus, the sum of the interior angles of a triangle is 180°.

tim bought all of the 2 3 over 4 lb packages for a party
How many pounds of meat fid tim buy?
Answer: he bought 1 and 1/2 pounds of meat. (also could be written as 1.5 pounds)
Step-by-step explanation:
We know that Tim bought all of the two 3/4 lb packages for a party.
Then he bought 2 packages. Such that each package has 3/4 lb meat.
Then the total amount of meat that Tim has is equal to 2 times the amount of meat in each package, this is:
Total meat = 2*(3/4 lb) = (6/4 lb)
and we can write 6 = 4 + 2
then:
Total meat = 6/4 lb = (4 + 2)/4 lb = (4/4 + 2/4) lb = (1 + 1/2) lb
So he bought 1 and 1/2 pounds of meat. (also could be written as 1.5 pounds)

A,E, and D are collinear. BCDE is a parallelogram. Find m
Answer:
B. 29º
Step-by-step explanation:
Given that BCDE is a parallelogram, then [tex]BE \parallel CD[/tex] and A, E and D are collinear. Then, angle E inside triangle ABE and angle D inside parallelogram BCDE have the same measure. That is:
[tex]\angle D = \angle E = 51^{\circ}[/tex] (1)
In addition, the sum of internal angles in triangles equals 180º, which implies that:
[tex]\angle A + \angle B + \angle E = 180^{\circ}[/tex] (2)
If we know that [tex]\angle B = 100^{\circ}[/tex] and [tex]\angle E = 51^{\circ}[/tex], then [tex]\angle A[/tex] is:
[tex]\angle A = 180^{\circ}-\angle B - \angle E[/tex]
[tex]\angle A = 180^{\circ}-100^{\circ}-51^{\circ}[/tex]
[tex]\angle A = 29^{\circ}[/tex]
Hence, correct answer is B.
Answer:
The answer would be be 29 degrees

B
Using the concept of rational numbers, it is found that the best method Toby could use is a multiplication of fractions, as the product of two fractions(two rational numbers) is always a fraction(rational number).
-------------
A rational number, no matter if an integer, a finite decimal or a repeating decimal can always be represented by a fraction.The product of two fractions will always result in a fraction, as the numerator of the multiplication is the multiplication of the numerator of the factors, and same for the denominator.Thus, since the product of two fractions is always a fraction, the product of two rational numbers is always a rational number.A similar problem is given at https://brainly.com/question/10814303

How do I find these equations using substitution y=-3x+5 and 5x-4y=-3 ?
Answer:
x=1
Step-by-step explanation:
you would change it to 5x-4(-3x+5)=-3, because you put the info for the first equation into the second equation.
5x-4(-3x+5)=-3
5x+12x-20=-3
17x-20=-3
17x=17
x=1
Answer:
(1,2)
Step-by-step explanation:
1) To solve using substitution, first isolate one of the variables in one of the equations. However, the y in y = -3x + 5 has already been isolated, so we don't need this step. Instead, take that value of y and substitute it for the y in the other equation, 5x - 4y = -3. So, substitute -3x + 5 for the y in 5x - 4y = -3 and solve:
[tex]5x-4(-3x+5)= -3\\5x+12x-20=-3\\17x-20=-3\\17x = 17\\x = 1[/tex]
2) So, x = 1. Now, take that value of x and substitute back into any of the equations to find the y value. (I chose to substitute it into y = -3x + 5, but either choice is fine). So, substitute 1 for the x in y = -3x + 5 and solve:
[tex]y = -3(1)+5\\y = -3+5\\y = 2[/tex]
So, y = 2. Thus, by knowing both x and y values, the solution would be (1,2).
