The elements are :
<span> 2,3,5,8,2.03,2.20,2.6,4.5
n = 8
</span>μ = ( <span>2 + 3 + 5 + 8 + 2.03 + 2.20 + 2.6 + 4.5
)/8 = 3.66625
sum = (</span> 2 - <span>3.66625)² + ( 3 </span><span>- 3.66625)² + ( 5 </span><span>- 3.66625)² + ( 8 </span><span>- 3.66625)² +
( 2.03 </span><span>- 3.66625)² + ( 2.20 </span><span>- 3.66625)² + ( 2.6 </span><span>- 3.66625)² + ( 4.5 </span>- <span>3.66625)²
= 30.44
∴ </span>The standard deviation = √ (30.44 / 8)
≈ 1.95 ( <span>to the nearest hundredth )</span>
Answer:
C
Step-by-step explanation:
One side is 60 so the other side is 60
X=20
4(20)-20=60
60=(4(20)-20)
60=80-20
60=60
kinda got a bit dum

(sorry I took so long to respond lol)
<span>5x / 25x^4 = 5/x^3
</span><span>x^3 / 5x^14 = 1/5x^11</span>t is nonequivalent
hope this helps
