Answer:

h=\frac{3}{2}

Step-by-step explanation:

V=\frac{1}{3} \pi r^2h

\frac{1}{18} \pi =\frac{1}{3}\pi  (\frac{2}{3} / 2 )^2 h

\frac{1}{18} =\frac{1}{3}  (\frac{2}{6})^2 h

\frac{1}{18} =\frac{1}{3}  (\frac{4}{36})h

\frac{1}{18} =\frac{4}{108} h

h=\frac{1}{18}*\frac{108}{4}

h=\frac{6}{4}

h=\frac{3}{2}

Dovator [93]
The confidence interval is from 0.2191 to 0.2649, given by

0.242\pm0.0229.

The z-score we need is found by first subtracting the confidence level from 1:
1 - 0.95 = 0.05

Divide that by 2:
0.05/2 = 0.025

Subtract that from 1:
1 - 0.025 = 0.975

Look this up in the middle of a z-table (http://www.z-table.com) and we see that the z-score is 1.96.

Now our confidence interval is given by
\overline{x} \pm z\times \frac{\sigma}{\sqrt{n}}
\\
\\0.242\pm 1.96 \times (\frac{0.037}{\sqrt{10}})
\\
\\0.242 \pm .0229
\\
\\0.242-0.0229=0.2191
\\
\\0.242+0.0229 = 0.2649

Zina [86]

hope this help Answer:( x - 3i√2)(x + 3i√2)

solve x² + 18 = 0

x² = - 18 ⇒ x = ±√- 18 = ±3i√2

factors are ( x - (3i√2))(x - (-3i√2))

x² + 18 = (x - 3i√2)(x + 3i√2
