7. 12, 24, 4, 18, 12, 9<br><br> Using the data, create a histogram.

Mnenie [13.5K]

Answer:

import pandas as pd

vec = pd.Series([7.12,24,4,18,12,9])

vec.plot(kind = 'hist')

Step-by-step explanation:

You can use python for that.

By doing

import pandas as pd

vec = pd.Series([7.12,24,4,18,12,9])

vec.plot(kind = 'hist')

And this is the result you get

Dianne purchased a ham for $45.15. How many pounds is the ham if it sells for $6.45 per pound?

Len [333]

It would be 7lbs, you divide the total amount by the amount per pound and you get the weight.

For the function given state the period f(t) =6sin(3t-pi/6)-1

$\bf \qquad \qquad \qquad \qquad \textit{function transformations}

% function transformations for trigonometric functions
\begin{array}{rllll}
% left side templates
f(x)=&{{ A}}sin({{ B}}x+{{ C}})+{{ D}}
\\\\
f(x)=&{{ A}}cos({{ B}}x+{{ C}})+{{ D}}\\\\
f(x)=&{{ A}}tan({{ B}}x+{{ C}})+{{ D}}

\end{array}$

$\bf \begin{array}{llll}

now, with that template in mind, let's take a peek at yours

$\bf \begin{array}{lllcclll}
f(t)=&6sin(&3t&-\frac{\pi }{6})&-1\\
&\uparrow &\uparrow &\uparrow &\uparrow \\
&A&B&C&D
\end{array}\\\\

period\qquad \cfrac{2\pi }{B}\iff\cfrac{2\pi }{3}$
