Answer:
The odds are 100 out of 200% for both to have heads.
The actual probility is 50%
Step-by-step explanation:
I think it'd be g = 2.
9g+2=20
9g=20-2
9g= 18
( You would divide both sides by 9 )
g = 2
The answer is 27
Remember that the number inside the lines are always positive so in this case it will be
|-8|+19 which will equal to
8+19=27
Given:
r = radius = 4
h = height = 12
dr = error in radius = 0.2
What we want to find
dV = error in volume
Use the derivative to find the differential dV
V = pi*r^2*h
dV/dr = d/dr[ pi*r^2*h ]
dV/dr = 2pi*r*h
dV = 2pi*r*h*dr
dV = 2pi*4*12*0.2
dV = 19.2pi
So if the error in measuring the radius is +-0.2 inches, then the error in the cylinder volume is +-19.2pi cubic inches (we either measure the volume to be 19.2pi cubic inches too big, or 19.2pi cubic inches too small)
----------------------------------------------------------------------------------
Final Answer: Plus or minus 19.2pi cubic inches
Note: your teacher may want you to drop the "plus or minus" part
