Answer:
Step-by-step explanation:
Solve for the mean (average) of the five test scores.
Subtract that mean from each of the five original test scores. Square each of the differences.
Find the mean (average) of each of these differences you found in Step 2.
Take the square root of this final mean from #3. This is the standard deviation.
Answer:
I would say that stands for "2 times the cube root of (5) * (5) * (7)"
Step-by-step explanation:
If one is already rolled as a 4, then there are only 6 other total combinations to get.
so what are sums to get an odd number?
4+1=5
4+3=7
4+5=9
so you have a 1/3 chance of getting an odd number, given that one of the dice is already a 4.
