A correlation coefficient of 1 or -1 indicates that the variables form a perfect linear relationship.
Set up a proportionality and simplify the fraction...hope this helps :)
66+6x 6 times 11 is 66 6 times x is 6x
Solution:
Consider the following expression:
2.5 x 8(20+5)
Solving the expression inside the parentheses first, we obtain:
2.5 x 8(25)
this is equivalent to:
2.5 x 200
this is equivalent to:
500
so that, we can conclude that the correct answer is:
500
