Answer:

s = sqrt [ Σ ( x i - x ) 2 / ( n - 1 ) ]

Step-by-step explanation:

where s is the sample standard deviation, x is the sample mean, x i is the ith element from the sample, and n is the number of elements in the sample. And finally, the standard deviation is equal to the square root of the variance.

HELP ME ASAP I HAVE SO MANY QUESTIONS THAT WILL SAY THIS BUT HELP MEEE!!!(timed!!)
tester [92]

Answer:

1. $8.30

Step-by-step explanation:

so 3 hats were purchased and each cost 15.50 so

15.50*3=46.50

and the rest of the 96.30 is 6 keychains so

96.30-46.50=49.80

and there is 6 keychains

49.80/6=8.30

Each key chain was $8.30

Claire's answer is unreasonable because when we got the price of the keychains all together in Claire's mind the total for the keychains would be $4.98, which we clearly got the total for the keychains at $49.80.
