HELP FAST PLEASE!!!!!
lidiya [134]

Alright, lets get started.

The answer Sandra got is correct that is zero but there are some mistakes she made while writing steps.

2 cot(\frac{-9\pi}{2})  =  2 cot(\frac{9\pi}{2}) Incorrect step

Because as per even/odd identity,

Cot (-Θ) = - cot (Θ)

Hence

2 cot (\frac{-9\pi}{2}) = - 2 cot (\frac{9\pi}{2})

Now,

It could be written as

-2 cot (\frac{9\pi}{2}) =   -2 cot (\frac{\pi}{2})


-2 * 0

0

Hence the answer is 0. : Answer

Hope it will help :)

In a bolt factory, machines 1,2, and 3 respectively produce 20%, 30% and 50% of the total output. of their respective outputs 5%
lorasvet [3.4K]

Answer:

a. 1/10 or 10%

b. 1/2 or 50%

Step-by-step explanation:

Since the combination of machines 1, 2 and 3 produce 100% of the total output when added together, then the probability of choosing a bolt at random that is defective is: 5 + 2 + 3 = 10% out of 100% or 10/100, which is 1/10 or 10%.

If the bolt that is choosen at random is defective, than the probability that it came from machine 1 is 5/10 or 1/2 which is also 50%.
