The bases in a major league diamond are locate at the corners of a 900 yd^2 square as pictures below. a player throws a baseball

Licemer1 [7]

To answer this, you will use the area of 900 square yards to determine the distances between the bases. Each side of the square is 30 yards, so it will be 30 yards from 1st to home and from 1st to 2nd.

The distance from home to 2nd is a diagonal in the square (the hypotenuse).

You will use the Pythagorean Theorem to find this distance.

a^2 + b^2 = c^2
30^2 + 30 ^2 = c^2
900 + 900 + c^2
1800 = c^2

The square root of 1800 is approximately 42.4 yards.

The ball travels approximately 42.4 yards.

A set of n = 25 pairs of scores (x and y values) has a pearson correlation of r = 0.80. how much of the variance for the y score

enot [183]

0.64 or 64% of the variance for the y scores is predicted by its relationship with x.

<h3>What is coefficient of determination?</h3>

The percentage of the variation in the dependent variable that can be predicted from the independent variable is known as the coefficient of determination, abbreviated R2 or r2, in statistics.

<h3>How to find the variance for the y scores?</h3>

given that

A set of n = 25 pairs of scores (x and y values) has a pearson correlation of r = 0.80.

now we have to find the variance for the y scores.

here, r=0.80 then ${r}^{2} = 0.64$

which means 0.64 or 64% of the variance for the y scores is predicted by its relationship with x.

$r = \sqrt{ {r}^{2}} \: or \: \sqrt{ {r}^{2}} \\ 0.80 = \sqrt{ {0.80}^{2} } \\ 0.80 = 0.80$
