Answer:
The correct option is;
We cannot infer a cause and effect relationship because we do not have a control group
Step-by-step explanation:
The treatment in research involves giving stimulus known as treatment to a group or portion of the sample which are then known as the treatment group while the remaining portion of the the sample are exempted from the stimulus. A successful treatment manipulation is one where members of the treatment group perform higher in the measured metrics of the research than members of the control group.
Given that the researchers gathered data from a random sample of drivers and measurement of several variables including the explanatory variable of the of the research without subjecting a sample to a treatment or having a control group we cannot infer a cause and effect relationship as there are no control group
It would take him four and a half days, or you could round it up to five if that's what you need. Either way, he would then have 3/4 of the fence done
All sides of the squares are congruent. This means that when solving for area:
base x height
the base and height would be the same length, 6.25
Multiply
6.25 x 6.25 = 39.0625
39.0625 ft² should be your answer (if i'm thinking of significant digits correctly)
If it should be a whole number, then 39 ft² is your answer
hope this helps
Answer:
(44.25/75)*100 or (44.25/3)*4
Step-by-step explanation:
Divide by the price of $44.25 by 75 (100% - 25%) and mulitily by 100
or $44.25 by 3 and multyply by 4. (25% is a quarter 1/4, so you need 4/4)
