For the data set 6,5,10,11,13, the mean, x, is 9. What is the standard deviation?

Ratling [72]

Answer:

3.39

Step-by-step explanation:

We will use SD formula to find our answer.

$\sigma=\sqrt{ \frac{\sum (x-\overline{x})^{2}}{N-1} }$

$\sigma$ = Standard deviation.

$\overline{x}$ = Mean.

N= Numbers of data-points.

We have been given that mean of our data set is 9. So we will find the square of each data point's distance to the mean.

Now let us substitute our given values in above formula.

$\sigma=\sqrt{ \frac{(6-9)^{2}+(5-9)^{2}+(10-9)^{2}+(11-9)^{2}+(13-9)^{2}}{5-1} }$

$\sigma=\sqrt{ \frac{(-3)^{2}+(-4)^{2}+(1)^{2}+(2)^{2}+(4)^{2}}{4} }$

Upon adding the square of distances we will get,

$\sigma=\sqrt{ \frac{9+16+1+4+16}{4} }$

$\sigma=\sqrt{ \frac{46}{4} }$

Upon dividing 46 by 4 we will get,

$\sigma=\sqrt{ 11.5}$

Upon taking square root of 11.5 we will get,

$\sigma=3.3911649915626341\approx 3.39$

Therefore, the standard deviation for our given data set will be 3.39.

On Tuesday, a coffee sho sold the following: 20 coffees for $2.85 each and 17 lattes f r $4.80 each, If the coffee shop had to p

almond37 [142]

Ok so to solve this problem we're going to need to find out how much money they made (their revenue) and the subtract the cost of paying the employees.

So, let's start by finding their revenue

Step 1: Multiply the cost of each beverage by the number sold

Coffees: 20 x 2.85 = 57

Lattes: 17 x 4.80 = 81.6

Step 2: add up the money made from the coffees and the money made from the lattes to get the total revenue

57 + 81.6 = 138.6

So the shop made $138.60 on Tuesday. Let's set that aside while we find out how much the shop's costs were.

Step 3: Find the price of paying two employees for 6 hours

2 x 6 x 14.5 = 174

So the shop had to pay the employees $174.00 for working there.

Step 4: Find the overall profit/loss by subtracting the cost from the revenue

138.6 - 174 = -35.4

So the shop had a loss of $35.40 on Tuesday.

Hope that helps! Feel free to leave a comment or send me a message if I can clarify anything :)
