Answer:

D) Standard deviation is 5.41

Step-by-step explanation:

We are given

count N = 9

Sum ∑xi = 113

Mean =  ∑xi /N = 12.55

Standard deviation = \sqrt{  \frac{(summation xi-mean)^2}{N} - (mean)^2    } where i = 1 to 9

 upon substituting the values we get

Standard deviation = \sqrt{29.277} = 5.41

HELP PLEASE!! A warehouse holds 460 boxes. They ship out 65 boxes each week. After how many weeks will they have less than 100 b
poizon [28]
Let's first define the variables:
 x = number of weeks.
 y = number of boxes after x weeks.
 We write the inequation that adapts to the problem
 y> -65x + 460
 For a number less than 100 boxes we have:
 100> -65x + 460
 We clear x:
 65x> -100 + 460
 65x> 360
 x> (360/65)
 x> 5.54
 Answer: 
 it will take more than 5.54 weeks for the warehouse to have less than 100 boxes
