Pl (06.03 mc) which of the following best describes the expression 9(x + 7)? the sum of constant factors 9 and x + 7 the product of constant factors 9 and x + 7 the product of a constant factor 9 and a 2-term factor x + 7 the sum of a constant factor 9 and a 2-term factor x + 7

Given the linear correlation coefficient r and the sample size n, determine the critical values of r and use your finding to state whether or not the given r represents a significant linear correlation. use a significance level of 0.05. r=0.105, n=15 a: critical values: r= +0.514, no significant linear correlations b: critical values: r= +0.514, significant linear correlation c: critical values: r= +0.532, no significant linear correlation d: critical values: r= 0.514, no significant linear correlation will mark brainliest !
