the answer is Let x be a random variable that represents the batting average of a professional baseball player. Let y be a random variable that represents the percentage of strikeouts of a professional baseball player. A random sample of n = 6 professional baseball players gave the following information.

x 0.350 0.270 0.340 0.248 0.367 0.269

y 2.8 7.0 4.0 8.6 3.1 11.1

Verify that Σx = 1.844, Σy = 36.6, Σx2 = 0.579554, Σy2 = 279.62, Σxy = 10.4864, and r ≈ -0.896.

Please solve. How could you use parallel lines to compare figures N and M? Explain your reasoning.
ra1l [238]

Figure N is essentially the translation of figure E three blocks to right and one block down

<h3>What are the similarities of M and N?</h3>

1) The length of M and N can be described by two parallel lines spaced 3 blocks apart where the parallel line on E and F are separated by a parallel line that is two blocks long on the left and one block long on the right.

2) Both height of  M and  N can be described by two parallel lines spaced 2 blocks apart  where the parallel The parallel line at the bottom is one block long, whereas the line at the top of E and F is three blocks long.

3) The interior of M an N can be described by parallel lines 2 blocks long in the horizontal portion and one block long in the vertical portion

The differences are

1) The difference between M and N is that the parallel lines used for the construction of E are all one block higher than that of F

2) The other difference is that all the lines used for the construction of the figure M are 3 blocks to the left of those used for the construction of N

Therefore Figure N is essentially the translation of figure E three blocks to right and one block down
