Answer:
Experimental but not double-blinded study
Step-by-step explanation:
The type of study being described is an Experimental but not double-blinded study. That is because it is a study that has a control group, dependent variable, and an independent variable all used in order to acquire specifically targetted data from the results that are derived from the experiment itself. Also since the scientists/researchers know exactly which lab sections are getting the extra review material (independent variable), then that makes this a non-double-blinded study.
Answer:
525,000 LL
Step-by-step explanation:
6 x 3 = 18 (days)
150,000 x 3 = 450,000
21 - 18 = 3 so 6 * 2 = 3 ( 150,000 *(divide) 2 = 75,000)
so 450,000 + 75,000 = 525,000
Answer:
Answer for A
Step-by-step explanation:
I don't know about B , Sorry for that.
<span>precision is after the decimal point.

Make an equation.
'is' is an equal sign
The blank can be 'x'
'of' = multiplication
18 = x * 30
Multiply:
18 = 30x
Divide 30 to both sides:
x = 0.6
Multiply by 100:
0.6 * 100 = 60%
