Answer:
Answered below.
Step-by-step explanation:
1) A double - blind study is simply an experiment in which neither the participants nor the people who carry out the experiment know who is receiving any particular treatment. This method is usually used in order to prevent a biased view in research results.
2) True because randomized simply means that subjects were assigned to the group randomly.
3) Placebo - controlled trial simply means that there was a control group that received only a placebo treatment which is mainly designed not to have real effect.
From unit conversion, it is found the following results:
6km ≈ 3.73 mi
2.5 L≈ 0.66 gal
90 lb ≈ 40.82 kg
<h3>
Unit Conversion</h3>
Units of measurement are part of our daily lives. There are different units for area, length, volume, mass, and others. Because of this, it is important to know converting them.
For solving this question you need some information as:
1 km = 0.621371 mi ( unit for length and distance)
1 L = 0.2641722 gallons (unit for volume)
1 lb = 0.453592 kg (unit for mass)
Therefore,
- If 1 km = 0.621371 mi, you will have:
1 km -------- 0.621371 mi
6 km -------- x mi
x= 6* 0.621371
x=3.73 mi
Thus, 6km ≈ 3.73 mi.
- If 1 L = 0.2641722 gallons, you will have:
- 1 L-------- 0.2647122 gal
- 2.5L -------- x gal
- x= 2.5* 0.2647122
- x=0.66 gal
- Thus,
- 2.5 L≈ 0.66 gal.
- If 1 lb = 0.453592 kg, you will have:
- 1 lb-------- 0.453592 kg
- 90 lb -------- x kg
- x= 90* 0.453592
- x=40.82 kg
- Thus,
- 90 lb≈ 40.82 kg

Answer:
11(9 - 2) - 3
Step-by-step explanation:
This is how you write the expression.
Three less means we have a -3.
11 times the sum of 9 - 2 means we have 11(9 - 2)
We put these together to get:
-3 + 11(9 - 2)
Or we can simplify it to:
11(9 - 2) - 3
