28^2=784
29^2=841
784<830<841
therefore sqrt784<sqrt830<sqrt841
therefore 28<sqrt830<29
Done!

Answer:
Step-by-step explanation:
There are four values 46, 51, 53, 59
we have to draw 2 sampler with replacement
sampler median samler median
46.46 46 53.46 49.5
46.51 48.5 53.51 52
45..53 49.5 53.53 53
46.59 52.5 53.59 56
51.46 48.5 59.46 52.5
51.51 51 59.51 55
51.53 52 59.53 56
51.59 55 59.59 59
sampling distribution of the median

46 1/16
48.5 2/16
49.5 2/16
52.5 2/16

16 n^2 -10n + 129 = 8n^2 -8
We collect the terms:
8n^2 -10n + 137 = 0
The steps for completing the square:
1) Move the "non X" (or "non N") term to the right:
8n^2 -10n = -137
<span>2)<span> Divide the equation by the coefficient of N² which in this case is 8
n^2 -1.2n = </span></span><span><span>-17.125
</span>
3) Take the coefficient of "N"; divide it by 2; square it; add it to both sides of the equation.
-1.2 / 2 = -.6
-.6^2 = .36
</span>
n^2 -1.2n +.36 = <span>-17.125
+.36
Take the square root of both sides:</span>
(n-.6)*(n-.6) = sq root(
<span>
<span>
<span>
-16.765
</span>
</span>
</span>
)
That's about as far as I can go.
Answer:
3/10
Step-by-step explanation:
9-6=3
both fractions have the same denominator so they keep it
9/10 - 6/10 = 3/10
<h3>3/10 is also 0.33</h3>
