Calculate for the mean/ average of the given numbers:
 
                             μ = (1 + 2 + 3 + 4 + 5) / 5 = 3

Then, we calculate for the summation of the squares of differences of these numbers from the mean, S
 
                             S  = (1 - 3)² + (2 - 3)² + (3 - 3)² + (4 - 3)² + (5 - 3)²
                                S = 10

Divide this summation by the number of items and take the square root of the result to get the standard deviation.

                              SD = sqrt (10 / 5) = sqrt 2  
                                    SD = 1.41

Thus, the standard deviation of the given is equal to 1.41.

What is 3x+4y=16 for x
sergiy2304 [10]
3x + 4y = 16           Write original equation     
3x + 4y - 4y = -4y + 16          Subtract 4y from each side
3x = -4y +16                    Simplify
3x/3 = -4y/3 + 16/3      Divide each side by three
x = -4y/3 +16/3             Simplify

I hope this helps!

IgorLugansk [536]

Answer:

Juan

Step-by-step explanation:

The number of pages that Ana, Hillary, Roger, and Juan can read in a day is shown below:

For Ana

Ana read 15% of her 46-page book.

= 15% × 46 pages

= 6.9 pages

For Hillary

Hillary read 11% of her 72-page book.

= 11% × 72 pages

= 7.92 pages

For Roger

Roger read 12% of his 68-page book.

= 12% × 68 pages

= 8.16 pages

For Juan

Juan read 14% of his 69-page book.

= 14% × 69 pages

= 9.66 pages

The person who can read greatest number of pages in a day also means the person who read the highest number of pages in a day.

From the calculation above, that person in JUAN because she can read 9.66 pages of her book in one day.
