Nun man I think you could be trippin
You'd use the equation a^2 + b^2 = c^2 (**** ^2 means squared****)
a = 60
b = 11
c = ?
60^2 + 11^2 = c^2
3600 + 121 = c^2
3721 = c^2
then just square root 3721 and c^2
c = 61 feet
Answer:
Option d is right
Step-by-step explanation:
We know that a linear correlation is a measure of association between two variables dependent and independent variable. r always lies between -1 and 1 both inclusive. If r is nearer to 0 weak correlation and if |r| is near to 1 there is a stronger correlation.
Positive sign of r implies positive association and negative r implies negative association.
Hence out of the four options given about correlation we have
Option a is right because removal of outliers confirm accurate correlation
Option B is right because only if linear pattern is visible, correlation will be right
Option C is right because only for numerical data r can be calculated
Option d is wrong because correlation lies always between -1 and 1 both inclusive.
