What is the standard deviation of the following data set 1,1.2,4,1.28,4.1,5.3?
VikaD [51]
Memorize the definition of standard deviation: the sd is the square root of the average of the squared deviations of the mean. Wow. Let's do it.

Step 1. First we need the mean. That's easy. Add them up and divide by the count. Check if you get 16.88/5 = 2.81333.

Step 2. Now we're going to subtract this from each of the values, and square the result. Don't worry about negative signs, the squaring will get rid of those. Example for the first number:

(1 - 2.813)^2 = 3.29

The list of numbers I get is (rounded, in reality round as little as possible):

3.29, 2.60, 1.41, 2.35, 1.66, 6.18

Step 3: Add them all up. I get 17.49. 
Step 4: Divide by the count of numbers. 17.49/6 = 2.91
Step 5: Take the square root from this result. SQRT(2.91) = 1.707305

TIP: Use excel to do all these steps, then run the set of numbers through Excel's built-in sd function (called  STDEV.P) and see that you get the same result!

Hayley borrowed $1,854 from her parents. She agreed to repay them in equal installments throughout the next 18 months. How much
Serggg [28]

Answer: $ 618

Step-by-step explanation:

Money borrowed =  $1,854

Total months taken to repay = 18  (Number of installments)

Money paid per month = \dfrac{\text{Money borrowed}}{\text{Number of installments}}

=\dfrac{1854}{18}=\$103

Now , money paid in 1 year = 12 x $ 103 =$ 1236     [1 year = 12 months ]

After a year , Haley still owe =  $1,854 -  $ 1236= $ 618

Hence, Haley still owe her parents $618 after a year .

A tour director collected $258 for 13 tour packages tour packages a cost $18 into a package requires $22 how many of each tour p
Lena [83]

Answer:


Step-by-step explanation:

X+Y = 13

 

$18 + $22 = $258

OR

18X+22Y=258

 

18X + 22(13 - X) = 258

 

18X + 286 - 22X  = 258

 

286 - 4X  = 258

 

-4X= 258 - 286

 

-4X = -28

 

X= 7

Y=6

 7 of the X tour  packages & 6 of the Y tour  packages
