The difference between an observational study and an experiment is thatA . in an observational study, only one group is studied, and in an experiment, two groups are studied.

B . in an observational study, the researchers do not control treatment, and in an experiment, they do.

C . in an experiment, cause-and-effect is analyzed, and in an observational study, it is not.

D . in an experiment, one group is studied over a short period of time, and in an observational study, the group is studied over a longer period of time.

Answers

Answer: (b) in an observational study, the researchers do not control treatment, and in experiment, they do.

Step-by-step explanation: In an observational study, only one group is studied, but in an experiment, more than one, may be two, three, etc. are studied, so option (A) is not correct. In an observational study, researchers control treatment but in experiment they do not, and so, option (B) is also incorrect. Option (D) is not correct, because a group is studied over a longer period of time in an experiment and the group is studied over a short period of time in observational study. The only correct option is (C) because cause and effect is studied in an experiment and are not studied in an observational study.

Hence, (C) is the correct option.

Rewrite the equation so that it does not have fractions 2/3x-4=5/6

Answers

Answer:

.6x - 4 = .83

Step-by-step explanation:

Final answer:

The equation 2/3x - 4 = 5/6 can be rewritten without fractions by finding the least common multiple of the denominators and multiplying each term by it, resulting in the equation 4x - 24 = 5.

Explanation:

To rewrite the equation without fractions, the first step is to find the least common multiple (LCM) of the denominators. The denominators in this equation are 3 and 6. The LCM of 3 and 6 is 6.

So, multiply each term by 6 to eliminate the fractions:

6 * (2/3x) - 6 * 4 = 6 * (5/6)

This simplifies to: 4x - 24 = 5

At this point, the equation is without fractions and you have successfully rewritten the equation so that it does not have fractions.
