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

2^4-1 so 2•2•2•2=16 and 16-1 is 15
Answer:
Step-by-step explanation:
Least to largest:
First compare the whole parts of the decimal number. The whole part with greater number will be the greatest number.
2) Then compare the decimal parts. Compare tenth place. The decimal number that has greater number in the tenth place will be greater.
3) If the number in tenth place is equal, then compare 100th place and so on
A) 15.99 ; 16 ; 16.02 ; 16.2

B) 32.32 ; 32.302 ; 32.032 ; 3.99
c) 7.666 ; 7.66 ; 7.6 ; 7.06
D) 57.68 ; 57.57 ; 57.057 ; 5.75
Answer:
Step-by-step explanation:
<u>Even function has following property:</u>
<u>It is easy to show this works with the second choice only. All the others don't work:</u>
- g(x) = (x - 1)² + 1
- g(-x) = (-x - 1)² + 1
This is not correct as x - 1 ≠ -x - 1 so as their squares, so g(x) ≠ g(-x)
The last two choices are not even similarly.
