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.

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).

Step-by-step explanation:

In this question, I see an outlier. Most of the time you may want to solve the inequality, but check how the answers are phrased in relation to the inequality. The equation shows a > symbol.

Answer A states, "save at least $72." If the inequality used a greater than or equal to sign this could work, yet it uses a > symbol. I would go with B & C, if you haven't chosen already.

Answer:

2 x  − 6

Explanation:

"Six less than.." means "Subtract 6 from".

Do not confuse this with "Six less..." which means "Subtract from 6".

Confusing, I know.

We know that "Double a number" means  

2 x , where  x  is your mystery number.

Therefore, we have:

2 x  −  6 , which translates to "6 less than 2x" or "6 less than twice a number"

Given:

Coordinates of point N = (-2,-6)

Point N is reflected over the y-axis to create point N ′.

Point N' is then reflected over the x-axis to create point N''.

To find:

The ordered pair that describes the location of N''.

Solution:

The coordinates of point N are (-2,-6). Point N is reflected over the y-axis to create point N ′.

[tex](x,y)\to (-x,y)[/tex]

[tex]N(-2,-6)\to N'(2,-6)[/tex]

Point N' is then reflected over the x-axis to create point N''.

[tex](x,y)\to (x,-y)[/tex]

[tex]N'(2,-6)\to N''(2,6)[/tex]

Therefore, the ordered pair for point N'' is (2,6).

Answer:

(-6,2)

Answer:

y = x - 2

Step-by-step explanation:

Find the slope using rise over run

(y2 - y1) / (x2 - x1)

Plug in the points:

(y2 - y1) / (x2 - x1)

(-5 - 4) / (-3 - 6)

-9 / -9

= 1

Using y = mx + b, plug in the slope and a point to solve for b:

y = mx + b

4 = 1(6) + b

4 = 6 + b

-2 = b

Plug in the slope and b to y = mx + b

y = 1x - 2

y = x - 2

So, the equation of the line is y = x - 2

This question is so hard

Any number times one equals itself, and any number multiplied by two equals itself plus itself, so 1*2=2 and 1*2=1+1. The transitive property of equality states that if x=y and y=z then x=z. Since both 1+1 and 2 are equal to 1*2, they must be equal to each other, so 1+1=2.

                                                  The answer is 2

Answer:

180° (in place of blank)

Step-by-step explanation:

GIVEN :-

PROCEDURE :-

∠C & ∠D are linear pair. (∵ They lie on same line)

⇒ ∠C + ∠D = 180°

⇒ ∠C = 180° - 127°

In a triangle , sum of its all interior angles equals to 180° (which is also known as "Angle Sum Property). So,

∠A + ∠B + ∠C = 180°

⇒ 75° + ∠B + (180° - 127°) = 180°

⇒ ∠B = 180° - 75° - (180° - 127°)

Answer:

180%

Step-by-step explanation:

m is in minutes so convert it in hours = 60m hrs

Speed is in metres per second, convert it in kilometers per hour= 18x/5

Now we’ve time and speed, put it in the formula

Distance = speed x time

= 18x/5 x 60m

= 216mx meters

Answer:

22 units

Step-by-step explanation:

The perimeter is all the sides of any polygon added up.

A rectangle has 4 sides, but we only need two sides to solve this because a rectangle has symmetry

There are two ways

Method 1:

x+2 + x-1 + x+2 + x-1   OR   2(x+2) + 2(x-1)

simplify: 2x + 4 + 2x - 2

              4x +2

Plug 5 into x: 4(5) + 2

Answer: 22

Method 2:

plug in x to get the sides: 7 and 4

now add: 7 + 7 + 4 + 4   OR   2(7) + 2(4)

simplify: 14 + 8

Answer: 22

The perimeter of the rectangle when x = 5 is 22 units.

Its the sum of length of the sides used to made the given figure.

The perimeter is all the sides of any polygon added up.

WE know that rectangle has 4 sides, but we only need two sides to solve because a rectangle has symmetry

Given that A rectangle has side lengths x + 2 and x - 1.

Then plug in x to get the sides: 7 and 4

Now add:

7 + 7 + 4 + 4  

OR  

2(7) + 2(4)

Then simplify:

14 + 8

22

Hence, the perimeter of the rectangle when x = 5 is 22.
