20^2 + 13.5^2 = c^2
            582.25 = c^2
          √582.25 = c
                 24.1 = c

hope this helps :)

\bf \textit{pythagorean theorem}\\\\
c^2=a^2+b^2\implies c=\sqrt{a^2+b^2}\qquad 
\begin{cases}
a=20\\
b=13.5
\end{cases}
\\\\\\
c=\sqrt{20^2+13.5^2}\implies c=\sqrt{582.25}\implies c\approx 24.12985702402730
\\\\\\
c\approx 24.1\impliedby \textit{rounded up}

vampirchik [111]

Answer:

The 95 percent confidence interval for the true mean metal thickness is between 0.2903 mm and 0.2907 mm

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.95}{2} = 0.025

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.025 = 0.975, so z = 1.96

Now, find the margin of error M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

M = 1.96\frac{0.000586}{\sqrt{59}} = 0.0002

The lower end of the interval is the sample mean subtracted by M. So it is 0.2905 - 0.0002 = 0.2903 mm

The upper end of the interval is the sample mean added to M. So it is 0.2905 + 0.0002 = 0.2907 mm

The 95 percent confidence interval for the true mean metal thickness is between 0.2903 mm and 0.2907 mm

You want to buy a jacket that is $75. Today it is marked down 33 one-third percent. The sales tax is 8%. How much will you pay?
lara [203]

Answer:

$54

Step-by-step explanation:

Price of jacket = $75

Markdown = 33.33...%

Sales tax = 8%

First we have to find the price of the jacket after the markdown.

75-33.33(75)

75-(25)

50

New price of jacket = $50

Now to calculate the price with sales tax.

50+0.08(50)

50+(4)

54
