Answer:
10. 48 degrees 11. Use explanation below. 12. 25 degrees 13.Use explanation below. 14. 63 degrees 15. Use explanation below. 16. 130.5 17. A. 48 degrees B. 90 degrees and C. 42 degrees 18. Explain
Step-by-step explanation:
10. All triangles angles add up to 180 degrees, so 100+32=132 and 180-132=48
11. Use the explanation above.
12. Using the rule above 88+57=145 and 180-145= 25
13. Use explanation above.
14. Add the two answers from 10 and 12. 48+25= 63
15. Use explanation above.
16. Using the triangle 180 degrees rule add 90 degrees (Angle a is a right angle which is always 90 degrees) to 40.5 degrees. 40.5 + 90= 130.5
17. You have angle A (48) angle B is a right angle aka 90 degrees and using the rule 90+ 48= 138 and 180-138= 42
18. I think you can explain it now (I hope)
Plug in x with -1

A negative number in parenthesis times an exponent is always positive.

Answer:
b. observational study
Explanation:
Observational studies are <em>commonly used in order to know the effects of a treatment or drug. </em>This study recruits people (the population of interest) to participate and these people are then interviewed and observed on a face-to-face visit. This allows clinical investigation regarding the safety of the new medication, including its <u>side effects and adverse effects.</u> So, this allows the researcher to know the symptoms of the new drug including whether it can reduce migraine to people.
The study also allows the employment of different designs, thereby paving way to a better patient care.
This is a reduction because the scale factor is in between 0 and 1.
