The teacher is using a number cube to select a row of students and then surveys every student in that row, which fits the definition of cluster sampling.
What is the sampling distribution?In statistics, sampling distribution refers to the study of numerous random samples drawn from a particular population depending on a specified property. The gained data paint a clear notion of the changes in the likelihood of the outcomes determined.
Cluster sampling is a type of sampling technique in which a group or cluster of units is selected from the population and then all units within the selected clusters are included in the sample.
In this case, the teacher is using a number cube to select a row of students and then surveying every student in that row, which fits the definition of cluster sampling.
Thus, the correct answer would be an option (A).

Answer:
∠BDC=43°
Step-by-step explanation:
Since ABCD is a rectangle, ∠ADC=90
∠ADC=∠BDC+∠ADB
90=(7x+1)+(9x-7)
90=16x-6
16x=96
x=6
∠BDC=7x+1
=7(6)+1
=42+1=43

Find tan 30°
Answer:
[tex]tan(30) = \frac{A}{B}[/tex]
Step-by-step explanation:
Given
The attached triangle
Required
Find tan(30)
Let the side opposite 30 degrees be A and the side adjacent 30 degrees be B
So [using tangent identity]:
[tex]tan(\theta) = \frac{Opposite}{Adjacent}[/tex]
This gives:
[tex]tan(30) = \frac{A}{B}[/tex]
11cm by 6 cm rectangle
Answer:
Question unclear.
If the question was about the perimeter of the rectangle, it is calculated as:
= (Length * 2) + (Height * 2)
= (11 * 2) + (6 * 2)
= 22 + 12
= 34 cm
If the question was bout Area, the area is:
= Length * width
= 11 * 6
= 66 cm²
Stephen’s lunch bill is currently at $8.33. Stephen orders a fruit salad for take-out, and wants to leave $2.25 as a tip for his server. He has $10 and a $5 bill. How much change after paying for his lunch, the fruit salad, and the tip?
Answer:
$4.42
Step-by-step explanation:
by combining $8.33 and $2.25 you get a combined total of $10.58 and if you subtract that from $15 you get $4.42 as the amount of money remaining.

What is the area of 19 centimeters?
Let's break this up:
Radius: 19
Diameter: 38
Circumference: 119.4
So...
The area of a circle with radius 19 is 1134
A = πr2 = π(d
2
)2 A = C2
4π
π = 3.1415
A = area
C = circumference or perimeter
r = radius, d = diameter
SOLUTION STEPS:
Area of a circle in terms of radius:
Area = π·r2 = 3.14·192 = 1134 square cm(*)
Area of a circle in terms of diameter:
Area = π·(d
2
)2 = 3.14·(38

)2 = 3.14·(19)2 = 1134 square cm(*)
Area of a circle in terms of circumference:
Area = C2
4π
= 119.42
4π
= 14256.36
(4·3.14)
= 14256.36
12.56
= 1134 square cm(*)
(*) 1134.1149479459 cm, exactly or limited to the precision of this calculator (13 decimal places).
Note: for simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.

HELP ASAP! I’m very confused and need help! Thanks!
Answer:
Step-by-step explanation:
Ok so basically 3 is 153 degrees and every line is 180 degrees, so 180-153=27. So 3 and 2 make a line, 2 is 27 degrees and 4 and 3 make a line so that makes 4 -27 degrees. 1 is vertical to 3 and if 2 and 4 are 27 degrees and makes the lines with the other angles that equal 27 degrees then 1 is also 153 degrees.

Sorry if this is hard to understand. Good luck! :)
Find the equation for the line that passes through (4, - 8) that has slope - 2. Give your answer in
point-slope form. You do not need to simplify.
Answer:
y+8=-2(x-4)
Step-by-step explanation:
point-slope form is y-y1=m(x-x1) where m is the slope, and (x1,y1) is a point.
We are given all of that information:
slope: -2
point: (4,-8)
substitute the numbers into the equation
y--8=-2(x-4)
we can make --8 to positive 8
so:
y+8=-2(x-4)
this is the equation in point-slope form
Hope this helps!

In the diagram below, OP is circumscribed about quadrilateral ABCD. What is
the value of x?
A. 52
B. 50
C.90
D. 92
The value of x is 50 because, in a quadrilateral, the sum of the opposite angles is equal to 180 degrees. option (B) is correct.
What is quadrilateral?
It is defined as the four-sided polygon in geometry having four edges and four corners and two pairs of congruent sides.
We have:
In the diagram below, OP is circumscribed about quadrilateral ABCD.
In a quadrilateral, the sum of the opposite angles is equal to 180 degree
x + 20 + 110 = 180
x + 130 = 180
x = 50
Thus, the value of x is 50 because, in a quadrilateral, the sum of the opposite angles is equal to 180 degrees. option (B) is correct.
