1 answer:
So, first of all, let's convert the fraction 
into a decimal, which would be 0.375 (3 divided by 8)
The snail travels this far in 3 minutes. To find out how far it travels in nine minutes, we have to find out how many times 3 goes into 9.
9 / 3 = 3
Now. we simply multiply our decimal by three in order to get our answer!
0.375 x 3 = 1.125 inches

Answer:
The standard deviation will be: 2.1
Step-by-step explanation:
We know that standard deviation is basically the square root of variance.
Using the formula to calculate the standard deviation
As
- The variance = s² = 4.4
so the standard deviation can be calculated as:
standard deviation
Therefore, the standard deviation will be: 2.1
