(will give brainliest to correct answer) in one study, it was found that the correlation coefficient between two variables is 1.0 which statement is true? a. there is almost no association between the variables. b. there is a strong negative association between the variables. c. there is a strong positive association between the variables. d. there is a perfect association between the variables.

D. there is a perfect association between the variables

i can answer this question sweetie!

step-by-step explanation:

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
