A is the correct answer. A coefficient is just a number that appears in front of a variable. Please note that a number that doesn't have a variable behind it is still a coefficient since there is technically a variable behind it with a power of 0.
Answer:
Systematic sampling
Step-by-step explanation:
An EPA contractor needing to test the concentration of a substance in ten samples out seventy samples provided form a single source at regular time intervals.
For the contractor to effectively carry out the testing he has to employ a Non-probability system of sampling which is called Systematic sampling, because in systematic sampling we can assume the population size (x ) which in this case is 70 and the sample size( n ) to be 10
He will have to select ; ( x / n )^th of the sampling frame for best results
Answer:
26+32=10v
add numbers
58=10v
10v=58
divide both sides by 10
v=5.8
There will be 6 vans needed
58/6=9.6
There will be 10 students in four vans, and 9 students in two vans.
Miguel's batting average is approximately 0.330
<u><em>Explanation</em></u>
Miguel Cabrera had 205 hits in 622 times at bat.
For finding the batting average, we need to <u>divide the number of hits by the total number of times</u> at bat and then round the result up to <u>three decimal places</u> as batting average is usually rounded to three decimal places.
So, Miguel's batting average 
≈ 0.330 (Rounded to three decimal places)
