600 − x = P
Answer:
Step-by-step explanation:
Let the number be 'x'
Quotient of a number and 4 =
Six less than the quotient of a number and 4 :
Equation:
The variation in any sample group is simply the square of
the correlation coefficient, that is:
variation = r^2
Therefore given an r value, we can simply directly
calculate for variation percentage.
variation = (0.743)^2
variation = 0.552 or 55.2%
