After a hurricane, a disaster area is divided into 200 equal grids. Thirty of the grids are selected, and every occupied household in the grid is interviewed to help focus relief efforts on what residents require the most. The sampling technique used is:_____.
A) Stratified Sampling.
B) Cluster Sampling.
C) Systematic Sampling.
D) Simple Random Sampling.
Answer:
B) Cluster Sampling.
Step-by-step explanation:
Cluster sampling refers to a methodology for probability sampling, in which researchers split the populace into several study groups or one can say clusters. And after this investigators pick random groups for collecting and analyzing data, using a systematic random or simple random sampling technique, depending on the research subject. As per the question, instead of 200 grids selected a cluster of 30 grids for the research and therefore it is a classic of cluster sampling.

Find the slope of the line shown
Answer: m= -1/2
Step-by-step explanation:
m is the gradient of a line. and the formula for gradient is (y2-y1)/(x2-x1)
first, find a point on the line, (-2,1) and that is equal to (x1,y1)
then find another point on the line, (2,-1) and that is equal to (x2,y2)
then substitute your points into the formula above and that is equal to
(-1-1)/(2-(-2))
= -2/4
= -1/2

Identify which equation represents a line perpendicular to the given equation 2x+5y=25
Answer:
y = 5/2x + 5
y = 5/2x - 9.5
Step-by-step explanation:
We need to solve for the y in the expresion of 2x + 5y = 25
[tex]2x + 5y = 25\\y = (25 - 2x)/5 \\y = 5 - 2/5x[/tex]
now we re-arrenge the factors in the form y = ax + b
y = -2/5x + 5
we reverse "a"
y = 5/2 + a
And now, we use a point in the other formula to solve for a:
original line:
y = 5 - 2/5x
X = 0 then Y = 5
now we solve for the general equation of the perpendicular equation:
[tex]y - y_1 = m ( x - x_1)[/tex]
[tex]y - 5 = 5/2 (x - 0)\\y = 5/2x + 5[/tex]
If we use a different point we get a different formula:
original line:
y = 5 - 2/5x
X = 5 then Y = 3
[tex]y - 3 = \frac{5}{2}(x - 5)\\y - 3 = \frac{5}{2}x -12.5 \\y = \frac{5}{2}x - 9.5[/tex]

Here is a picture of you don’t understand the question ⬆️
Answer:
Um its 2.83
Step-by-step explanation:
This is a 5th grade quesion
The value of each digit in a number is known as the place value. The 5 in 350. The value of √8 rounded off to the nearest hundredth is 2.83.
What is the place value of a digit in a number?The value of each digit in a number is known as the place value. The 5 in 350, for example, represents 5 tens, or 50, whereas the 5 in 5,006 represents 5 thousand, or 5,000. It is critical that children that while a digit can be the same, its value is determined by its position in the number.
Identification of the place value of a digit in a number:
The place values on the left of the decimal point start as ones, tens, hundreds, and so on.The place value on the right of the decimal point starts from the point and goes to the right as tenths, hundredths and so on.The tens mean multiply by 10.The tenth means the tenth part of that digit which is that digit divided by 10.Given √8 whose approximate values to its nearest hundredth can be written as,
The value of √8 = 2.8284271247
Round 2.8284271247 to its nearest hundredth.
We have,
2.8(2)84271247
2 is in the hundredth place.
We will round 284 to its nearest hundredth.
It will round to either 200 or 300.
Since it is 284 is more than 250 we will round to 300.
Therefore, 2.8300 is our answer.
Thus, the value of √8 rounded off to the nearest hundredth is 2.83.
