The correct answer is B. Stratified sampling is used since the field is divided into subplots and a random sample is taken from each subplot.
Explanation:
Sampling refers to the process followed by researchers to select a group of individuals from a larger group; considering in most studies it is not possible to analyze all the population. In the case of stratified sampling, this involves dividing the general population into smaller groups, which are known as strata; after this, the researcher selects a specific number of individuals from each strata. This method guarantees the sample is selected randomly, and therefore the study is not biased. Stratified sampling was the method used in the example described because, in this, the general population (46-acre field) was divided into subplots that represent the strata. Also, after this, the researcher selected one random sample.
Answer:
x>=35
Step-by-step explanation:
-4(x+10)>= -7x + 65
-4x-40>= -7x+65
-4x+7x>=65+40
3x>=105
x>=105/3
x>=35
<em>1 x 42</em>
<em>2 x 21</em>
<em>3 x 14</em>
<em>6 x 7</em>
Step-by-step explanation:
We need to find factors of 42.
Factors: <em>Two numbers when multiplied if give you the required number then those 2 numbers are factors o that number.</em>
So, Factors of 42 are:
<em>1 x 42</em>
<em>2 x 21</em>
<em>3 x 14</em>
<em>6 x 7</em>
Only these numbers when multiplied will give 42.
So, All these numbers are factors of 42

Answer:
yes
Step-by-step explanation:
because its true
The answer would be <span>6.5.12
A triangle couldn't be made if the total sum of the two shortest side is less than the longest side. In this case, the two shortest side would be 5 and 6. The longest side would be 12.
If you try to add the two lowest side, the result would be 5+6=11. That means even if you make the triangle with 179.99 degrees that the 5 and 6 look like a straight line, the longest side it can achieve is 11.</span>
