Answer: V20

Step-by-step explanation:

Let's go down the list, shall we?

First, V64. I am going to assume that the V is a square root. If you take the square root of 64 you would get 8, which is not an irrational number.

2/2 would be one of the easiest, its just 1 if you simplify it

(16 would be a rational number, even if you took the square root.

4 is four, a rational number

V20 is an Irrational number, again, assuming that the V is a square root symbol, and you took the square root of it, you would get 4.472135955... an infinite number without a pattern

And 5 is just five, a whole number

Please answer all three questions Pleaseeeeee tysmm <3

Answer: 2 3/4 > 2.68 is correct (only)

Step-by-step explanation: 2 3/4 = 2.75, and 2.75 is greater than 2.68

The rest are incorrect. 7.895 * 10^2 (100) = 789.5, and 5.43 * 10^3 (1000) = 5430. So 789.5 > 5430 is false.

Sqrt(63) = 7.93, and 7.93 > 8.11 is false.

Absolute values ( | | ) mean that no matter if it is negative or positive, it will become positive (unless the negative sign is outside the absolute value). 1.5 > 3.2 is false, and even without the absolute value, -1.5 is still less than 3.2

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
