The operating costs for each machine for one day have an unknown distribution with mean 1610 and standard deviation 136 dollars.
BabaBlast [244]

Answer:

20.27

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean \mu and standard deviation \sigma, the sample means with size n of at least 30 can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}

Using the Central Limit Theorem for Means, what is the standard deviation for the sample mean distribution?

This is s when \sigma = 136, n = 45. So

s = \frac{136}{\sqrt{45}} = 20.27

So the correct answer is:

20.27

Solve the inequality 3k &gt; 5k+12
Natali5045456 [20]

Alright, let's solve this problem! :)

<u>First we need to subtract 5k from both sides.</u>

3k−5k>12

<u>Then we simplify 3k - 5k to -2k.</u>

-2k > 12

<u>Now we divide both sides by -2.</u>

k < -12/2

<u>Now we simplify 12/2 to 6.  </u>

k < -6

✔️Done!

Have an amazing day!
