Find |−3/5|+3/4. Write your answer as a mixed number in simplest form.

1 7/20

Step-by-step explanation:

|-3/5|+3/4= 3/5+3/4

= 27/20

= 1 7/20

 r represents a significant linear correlation.

Step-by-step explanation:

GIven : Linear correlation coefficient: r = 0.543

Sample size: n= 25

Significance levle:

Degree of freedom : n-2 = 25-2=23

Now, we check r critical value table for value with df = 23 and .

Critical value = ±0.396  [From r critical value table]

Since r = 0.543 > 0.396, that means there is significant linear correlation.

Hence,  r represents a significant linear correlation.
