Lets take this problem as 25/8 - 15/8. This is both the fractions in improper form. Subtract 25 and 15 and divide the answer by 8 so 10 divided by 8 which is equal to 1 1/4
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
hope this helps :)
Answer:
the answer is c because as you can see the shape is now on the other side of the side and is clockwised over
Answer:
convert the expression for N into logs
evaluate those logs using a log table
thus determine log N
calculate antilog of log N
Thus,

Answer:
1. Placebos are used to randomly assign participants to treatment or control ?
False.
2. Using a random chance procedure to assign subjects to treatment or control reduces bias ?
True.
3. A well-designed placebo allows an experiment to be conducted blind. ?
False.
4. In an observational study, the investigators assign the subjects to treatment or control. ?
False.
5. In a blind experiment, the subjects do not know whether they are in the treatment group or control group. ?
True.
6. Placebos are used so that even the people who do not receive a treatment can benefit from the study. ?
True.
7. A placebo is used in all controlled experiments. ?
True.
8. Controlled experiments can be randomized or nonrandomized.
True.
Step-by-step explanation:
To enable the results from the control group to be compared to the results of a treatment group, placebos are administered to the control group while the treatment or independent group receives the real treatment. Randomization is the process for assigning participants to treatment or control groups, not placebos. The reason for using a random chance procedure to assign subjects to treatment or control groups is to reduce bias.
