Hi,

The total amount is $1,350.

<em />
<span><em>So, firstly we'll start off with the easiest one. We know that they bought a cake for </em><em>$250</em><em>. We also know that there were </em><em>50 people </em><em>invited. Appetizers per person cost $2. So we multiply $2 by 50 people. That's $100. They also charge $20 per person for the main course. Now we multiply $20 by 50 people and get $1,000. Now we add $1,000, $250, and $100 to get our total!</em></span>

We have a sample that in fact represents the population.

We have to calculate the standard deviation of this population.

The difference between the standard deviation of a population comparing it to the calculation of the standard deviation of a sample is that we divide by the population side n instead of (n-1).

We have to start by calculating the mean of the population first:

\begin{gathered} \mu=\dfrac{1}{n}\sum ^n_{i=1}\, x_i \\ \mu=\dfrac{1}{6}(37+38+39+40+39+11) \\ \mu=\dfrac{204}{6} \\ \mu=34 \end{gathered}

Now, we can calculate the standard deviation as:

\sigma=\sqrt[]{\dfrac{1}{n}\sum^n_{i=1}\, (x_i-\mu)^2}\begin{gathered} \sigma=\sqrt[]{\dfrac{1}{6}((37-34)^2+(38-34)^2+(39-34)^2+(40-34)^2+(39-34)^2+(11-34)^2)} \\ \sigma=\sqrt[]{\frac{1}{6}(3^2+4^2+5^2+6^2+5^2+(-23)^2)} \\ \sigma=\sqrt[]{\frac{1}{6}(9+16+25+36+25+529)} \\ \sigma=\sqrt[]{\frac{1}{6}(640)} \\ \sigma\approx\sqrt[]{106.67} \\ \sigma\approx10.33 \end{gathered}

Answer: the standard deviation of this population is approximately 10.33

A health club charges a $50 initial fee , plus $2 for each visit . Marsha has spent a total of $144 at the health club this year
AVprozaik [17]
Use these variables to make an equation-
y is the total amount.
$50 is where you start charging(y intercept, variable b).
x is how many visits Marsha made.
The equation can be in slope-intercept form (y=mx+b)-
$144=$2x+50
Solve for x using inverse operations.

Subtract 50 from both sides-
144-50=2x+50-50
94=2x

Divide 2 from both sides-
94/2=2/2
x=47

Marsha made 47 visits to the health club.
