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:
$63.92
Step-by-step explanation:
The answer to your question is 2345
Okay so for number one you use PEMDAS so you can either divide 144 by 12 first or multiply 5 and 6 or divide 6 by 3.
Normally, I do multiplicarion first so the first step would be to multiply 5 and 6 with is 30 so the new equation is 144/12+30/3 okay and then do the divisions.
So the new equation would be 12+10 and which equals 22
And for number two since you have a variable you can't use PEMDAS so just distribute the 11 but only to the ones in the parentheses.
So the new equation turns out to be 11x-33+5=0
Okay then, since you need to figure out what x is, you move over -33 and 5 by adding 33 and subtracting 5 which gives you 11x=33-5
And then just solve 11x=28 and x is a decimal number. (x=2.55)
398.24
76 x 524/ 100
= 398.24
Hope this helps :) have a great day/ night!!!!!!
