Answer:
Okay so you first need to figure out what your variables are in the equation given. It tells you pi is 3.14. on the top of the cylinder it shows that the radius (r) is 2. the height (h) is shown on the cylinder as 4. Now all you have to do is plug in the values for the variables into your calculator. You have (2) times (3.14) times the radius (2) and you square the radius. then you add (2) x (3.14) x (2) x (4). So if you put it in your calculator it would look like this: (2)(3.14)(2)^2+(2)(3.14)(2)(4)=75.36 Your answer is 75.36

Strange question to me
Answer:
-115/69
Step-by-step explanation:
12(6x + 10) + x = 9x + 5(1 - x)
72x + 120 + x = 9x + 5 - 5x
73x + 120 = 4x + 5
69x = 5 - 120
69x = -115
x = -115/69

Step-by-step explanation:
Given
-- total
--- defective
--- selected
Required
The probability of rejecting the batch
This means that at least one of the selected piece is defected.
So, we first calculate the probability that all the selected piece are accepted.
So, we have:

The denominator decreases by 1 because it is a probability without replacement; 180 is subtracted from the numerator to represent the number of non-defective CDs
So, we have:


Using the complement rule, the probability that the batch will be rejected is:
