<h2>Answer:</h2>
Option: A is the correct answer.
A. -0.903
<h2>Step-by-step explanation:</h2>The formula to calculate correlation coefficient r is given by:
x y xy x² y²
4 23 92 16 529
5 12 60 25 144
8 10 80 64 100
9 9 81 81 81
13 2 26 169 4
-------------------------------------------------------------------------
∑ 39 56 339 355 858
Also n=5 ( as there are 5 data points )
Hence, we get:
Hence, the r-value of the following data, to three decimal places is:
A. -0.932
Answer: you already gave the answer. To check it submit
factor 3x^4y^3 − 15x^2y^2 + 6xy
to Wolfram Alpha.
3xy(x^3y^2 − 5xy + 2) is the "irreducible factorization".
