Just line up the decimals and then you add. But after you finished adding, make sure you just straight up bring the decimal down to your final answer to the question.
The volume of the baseball is <span>65.8
r = 1/2 d
r = 1/2 5.1
r = 2.505
</span>V = 4/3 π r^3
V = 4/3 π 2.505^3
V = 65.8
I hope this helps!
Answer:
Step-by-step explanation:
We are given that
Mean,
%=68.5/100
Standard deviation, 
%=8.2/100
We have to find the probability that a student who wrote the examination had a mark between 80% and 100%.
We know that
Using the formula
(10+×)^2
expand
(10+x)(10+x)
multiply
100+10x+10x+x^2
add
100+20x+x^2
rearrange
x^2+20x+100
if this is what you mean this is the answer if you want to know what x is just set ()=0 and solve
x+10=0
x=-10
but I believe you are asking for the equation hope that helps let me know :)
