V=basearea times 1/3 times height
basearea=6<span>4π m2
hmm, they try to make it difficult
basearea=circle=pir^2
pir^2=64pi
divide by pi
r^2=64
sqrt
r=9
h is 4 les than 3 time r
h=-4+3(8)
h=-4+24
h=20
v=1/3*64pi*20=1280pi/3 m^3=1350.4

<h3>Simplifying </h3>
9x + -31 = 43
<h3>Reorder the terms:</h3>
-31 + 9x =43
<h3>Solving</h3>
-31 + 9x =43
<h3>Solving for variable 'x' .</h3><h3>Move all terms containing x to the left, </h3>
Add '31' to each side of the equation .
0 + 31 +9x = 43 + 31
<h3>Combine like terms: </h3>
-31 + 31 =0
0 + 9x = 43 +31
9x = 43 + 31
<h3>Combine like terms:</h3>
43 + 31 =74
9x = 74
<h3>Divide each side by '9'</h3>
x = 8. 222222222
<h3>Simpifying</h3>
x = 8.222222222
Answer:
x = 2
Step-by-step explanation:
(x + 50)/2 = 13x, first multiply both sides by 2
x + 50 = 26x, next subtract x from both sides
50 = 25x, finally divide both sides by 25
2 = x
Mean = 60 / 4 = 15
13 - 15 = -2
17 - 15 = 2
9 - 15 = -6
21 - 15 = 6
Total of squares = 4 + 4 + 36 + 36 = 80
because this is a sample we divide this by n - 1 ( = 3)
Standard deviation = sqrt (80/3) = 5.16 answer
