Answer:
The researcher should use correlation analysis for his studies.
Step-by-step explanation:
What is correlation?
Correlation is a statistical tool used to quantify the degree to which two variables are related. Through the correlation analysis, you evaluate correlation coefficient that tells you how much one variable changes when the other one does. Correlation analysis provides you with a linear relationship between two.
Types of correlation
1. Positive, Negative or Zero Correlation:
2. Linear or Curvilinear Correlation:
3. Scatter Diagram Method:
4. Pearson's Product Moment
Coefficient of Correlation:
5. Spearman's Rank Correlation
Coefficient:
Answer:
The rate of change is -5
The initial value is 25
Step-by-step explanation:
Since, this is a linear relation
so, we can select any two points and find equation of line
points are (1,20) and (3,10)
so,
now, we can find slope
now, we can plug values
now, we can use point slope form of line
now, we can plug values
now, we can solve for y
we know that
slope is the rate of change
So, the rate of change is -5
For finding initial value , we can plug x=0 and find y
So, initial value is 25
First do 10x7 =70
Since there’s 4 sides with this measure mentally do 70x8=560
560
10x8.7=87
87+560=647
647sq feet
Answer: its square.
Step-by-step explanation:
Answer:
The original price was $700.
50% of 700 = 350
