Answer:
s=10
Step-by-step explanation:
Basically, the range rule-of-thumb is that the range is generally about four times the standard deviation.
<u>First, we find the range:</u>
Range=Maximum-Minimum
Range=100-60
Range=40
<u>Next, divide the range by 4 to get the standard deviation</u>
Range=4(Standard Deviation)
40=4(Standard Deviation)
10=Standard Deviation
Therefore, s=10, which is the standard deviation
Answer:
The answer would be A and D, I just took the quiz
Step-by-step explanation:
The answer is 4 if I am correct
I would find the common factors between all of them, and settle with the factor 3.
If I have 3 tanks:
12/3 = 4
24/3 = 8
30/3 = 10
In each of the 3 tanks, there will be 4 angel fish, 8 sword fish, and 10 guppies.
I hope I helped :)
(I hope I didn't misunderstand the question, so if I did, I'm really sorry about that.)
