A sample is said to be representative if the selection made form have population is free of bias. Evaluating the selection criteria listed above :
Sample 1 will not likely be representative as students who do not belong to either a sorority or fraternity are automatically exempted from the selection. Sample 2 will not likely be representative because not all students play a varsity sport, hence students who do not play a varsity sport won't have a chance of being selected. Sample 3 is a convenience sampling technique, they often exhibit sampling bias hence, sample 3 is not representative of the population. Sample 4 will not likely be representative as students taking other courses aside humanities have no chance of being selected.Therefore, all the sampling methods are not representative of the population of first year student.

Answer:
D
Step-by-step explanation:
The graph G(x) is moved to the left by 1.
So it would be G(x) = (x+1)^2
The equation of the blue graph is,
⇒ g (x) = (x + 1)²
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;

The restriction of the domain of the function will be y = (x - 2)², x ≥ 2. Then the correct option is B.
What is a function?A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.
Let the point (h, k) be the vertex of the parabola and a be the leading coefficient.
Then the equation of the parabola will be given as,
y = a(x - h)² + k
Then the parabolic function is given below.
y = (x - 2)²
The restriction of the domain will result in the inverse being a function given as,
x - 2 ≥ 0
x ≥ 2
The restriction of the domain of the function will be y = (x - 2)², x ≥ 2. Then the correct option is B.

we have to find the measure in degrees (pi)/4.
now, we know that,
Measure of an Angle in Degrees = 180°
Measure of an Angle in Radians is:
180° × (π/180°) = π = 3.14 Rad
so, we have,
π/4
= π/4 × (180°/π)
=180 /4
=45°
Hence, the measure in degrees (pi)/4 is 45°.

Area and perimeter for this rectangle
Answer:
perimeter = (8x + 3mm + 5mm) ×2
area = (8x + 3mm) × 5mm
Answer:
Perimeter: 48mm
Area: 95mm
Step-by-step explanation:
Perimeter=2(l+w)
2((8x+3)+5)
-8x=2(3+5)
-8x=2(8)
-8x=16
x=2
2((8(2)+3)+5)= 48
So the perimeter is 48mm
Area=wl
l=19mm
w=5mm
19*5=95mm
So the area is 95mm

for z-
135
98
82
90
Answer:
y = 27°z = 98°Step-by-step explanation:
The interior angle marked 5y is the supplement of the adjacent exterior angle marked 45°.
5y + 45° = 180°
5y = 135° . . . . . . . . subtract 45
y = 27° . . . . . . . . divide by 5
__
The sum of the interior angles of a pentagon is (5-2)(180°) = 540°.
90° +5y +z +82° +135° = 540°
Using y=27°, we can subtract 442° from both sides to get ...
z = 98°
_____
Additional comment
You might recognize that the downward-sloping diagonal sides of the figure are parallel, so z and 82° are consecutive interior angles, hence supplementary. This fact means you don't have to be concerned with the other three angles in the figure to find the value of z: 180° -82° = 98°.
