Step-by-step explanation:
These have been rounded up by the way,
I converted it to decimal and percent form
Answer:
4A/ (πa) = b
Step-by-step explanation:
A = πab/4
Multiply each side by 4
4A = 4πab/4
4A = πab
Divide each side by πa
4A/(πa) = πab/ πa
4A/ (πa) = b
The width is basically the diameter, and all you have to do is divide by 2 to get the radius.B is the name for base. I think the formula for a triangle is 1/2 bh. and for the circle c=pieD i hope that helped!
Answer:
2
Step-by-step explanation:
Given that:
Flawed bulbs = 4
Not flawed = 26
Total examined = (flawed + not flawed)
Total examined = (4 + 26) = 30
P(flawed) = flawed / total
P(flawed) = 4 / 30 = 0.1333333
If 15 is examined :
Expected number of flawed bulbs :
(4/30) * 15 = 2
Answer:

Step-by-step explanation:
You need to apply the chain rule here.
There are few other requirements:
You will need to know how to differentiate
.
You will need to know how to differentiate polynomials as well.
So here are some rules we will be applying:
Assume 




Those appear to be really all we need.
Let's do it:






I tried to be very clear of how I used the rules I mentioned but all you have to do for derivative of natural log is derivative of inside over the inside.
Your answer is
.
