<h3>Answer: 42 degrees</h3>

Reason:

Use the inscribed angle theorem. Central angle DCE subtends the arc DE, so angle DCE = 84 degrees. Inscribed angle EFD is also subtending this same arc (DE), meaning we cut the arc/central angle measure in half to get 84/2 = 42.

All you had to do was plug in the value for c or b and solve. You can tell this is most likely correct because you see patterns for both variables. C is going up by threes, while b is going up by nines.

Given the linear correlation coefficient r and the sample size n, determine the critical values of r and use your

Mila [183]

The critical value of r is mathematically given as r = +0.487, with no significant linear correlation. Option A.

<h3>What are the critical values of r?</h3>

Question Parameters

r = -0.868

n = 5

df = 5 - 2

df = 3

$\alpha / 2 =0.025$

Critical values $r= \pm 0.878$

Generally, there exists no linear correlation between the Critical values

as r=0.878

In conclusion, Critical values: r = +0.487, no significant linear correlation
