Answer:
Define two roughly identical sets.
Reduce the chance of bias.
Step-by-step explanation:
In this experiment, Daniel performs a random assignment in order to stablish two separate groups with roughly equivalent ability to do barbell curls. Two different treatments (verbal encouragement and silence) are then applied in order to verify for a cause and effect relationship. If the groups were not randomly assigned, then the experiment could be biased.
Our ratio is 5 : 2.
Once we know our ratio, we just have to figure out equivalent ones to fill in the chart. If it helps, feel free to think about this like a fraction! Fractions and ratios are pretty much interchangeable.
5 / 2 = ? / 4 = 10 / 4
10 : 4
5 / 2 = 25 / ? = 25 / 10
25 : 10
5 / 2 = ? / 20 = 50 / 20
50 : 20
Hope this helps!
Given:
The three points are (-7,134), (-3,10) and (5,50).
To find:
The equation of parabola using quadratic regression.
Solution:
The general equation of quadratic regression is
...(i)
The three points are (-7,134), (-3,10) and (5,50).
Using the graphing calculator, we get a=3, b=-1 and c=-20. Putting these values in (i), we get
Therefore, the equation of parabola is and the missing values in the given equation are 3, -1 and -20.
