Me victor, vladimir , and vivian each has a different set of data points. each used the linear regression feature of his/her graphing calculator to find a linear function that models his/her data. the value of the correlation coefficient (r) associated with victors function was -0.91, the value or r for vladimir’s function was 0.73, the value of r for venus was -0.44, and the value of r for vivian’s function was 0.88. who has the best model for his or her data. a) venus b) victor c) vivian d) vladimir

B) Victor

Step-by-step explanation:

A positive value for r implies a positive linear correlation, while a negative value for r implies a negative linear correlation. The

closer |r| is to 1, the stronger the correlation, and the stronger the correlation, the more reasonable the data model. Since |–0.91| =

0.91, |0.73| = 0.73, |–0.44| = 0.44, and |0.88| = 0.88, the person with the most reasonable model for his or her data is B) Victor!

Hope this helps, have a good day. c;

answer:   n ≤ -3 or n < -5

step-by-step explanation:

-5 + 2n ≥ -11

+5             +5

2n ≥ -6

2/2 ≤ -6/2

n ≤ -3

-6 - 10n > 44

+6           +6

-10n > 50

-10/-10 50/-10

n < -5

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
