Answer:

An experimental study because it will give the most accurate results.

Step-by-step explanation:

The observational study could also be somewhat useful, but the most accurate results will come from an experimental study. You will test the difference in DNA, blood pressure, and such. Whilst, the observational study, you only can observe the effects from the outside. The sample studies mean nothing because you can't test both sides of the complete study.

What 5 consecutive odd numbers equal 200
dimulka [17.4K]

Answer:

{36, 38, 40, 42, 44}

Step-by-step explanation:

You are implying that you are adding up 5 consecutive numbers, and should use the word "add" or the word "sum."

"The sum of 5 consecutive odd numbers is 200" leads to:

x + (x+2) + (x+4) + (x+6) + (x+8) = 200.  Note how each number is 2 more than the number preceding it.  In this way you can guarantee that all of the 5 numbers are odd.

Summing up, we get 5x + 20 = 200, or 5x = 180.

Dividing both sides by 5, we get x = 36.

Then the 5 consecutive integers are

{36, 38, 40, 42, 44}.  These add up to 200.

Unfortunately, these are consecutive EVEN numbers, not odd numbers.  

Please ensure that you have copied down this problem correctly.
