The answer is actually 5.25 because i took the test and use the other users answer and it was wrong.
Answer: D
Step-by-step explanation:
Standard Deviation σ2 =
Σ(xi - μ)2/N
=(1 - 5.3)2 + ... + (9 - 5.3)2/10
=68.1/10
= 6.81
σ = √6.81
= 2.60959767014
B) σ2 =
Σ(xi - μ)2/N
=(3 - 61.7)2 + ... + (99 - 61.7)2/10
=58414.1/10
= 5841.41
σ = √5841.41
= 76.429117488036
C) (1 - 11.4)2 + ... + (1 - 11.4)2/10
=8758.4/10
= 875.84
σ = √875.84
= 29.59459410095
D) (79 - 79)2 + ... + (79 - 79)2/10
=0/10
= 0
σ = √0
= 0

<h2>Greetings!</h2><h3>When multiplying two roots together that are the same inside the root, you can simply multiply the two roots together:</h3>
x = 2
<h3>Then you can multiply this product by the number infront of the first root:</h3>
2 x 4 = 8
<h3>So the answer would be 8!</h3><h2>Hope this helps!</h2>
