Answer: Strong negative
Step-by-step explanation:
Correlation coefficient tells about the strength ( Strong , moderate or weak ) and direction ( positive or negative) of the relationship between two quantities.
- Strong correlation: The value of correlation coefficient lies between -1 to -0.5 or 0.5 to 1.
- Moderate correlation : The value of correlation coefficient lies between -0.5 to -0.3 or 0.3 to 0.5.
- Weak correlation : The value of correlation coefficient lies between -0.3 to -0.1 or 0.1 to 3.
The given correlation coefficient :-0.898
Since, it lies between -1 and -0.5 and has negative sign, it means it indicates a strong negative between the two things.
Hence, the correct answer is "strong negative
".
(4,?) is on the line y = 2x 3
The line y = 2x 3 is in slope-intercept form
2 = slope
3 = y intercept
A line perpendicular to the line y = 2x 3 will have a slope of 1/2 which is the inverse reciprocal of 2
y = 1/2x + b
Use the point you want to go through to find 'b'
4 = 1/2(2) + b
4 = 1 + b
b = 5
y = 1/2x + 5
Answer = 2;(4,2) is on the line y = 2x 3
