Answer: The first one

Step-by-step explanation: first you have to subtract 5 from both sides and then you have -6n < 6 . Then you have to divide both sides by -6 then you get n < -1.

Solve for x -6 &gt;_ 10 - 4x
Otrada [13]

We are given this inequality,

-6\geq10-4x

We will follow these steps to solve it:

Step 1:

First let us bring 10 to the left side.

10 is in addition on right, so we apply opposite operation of addition that is subtracting 10 from left side, we get

-6-10\geq-4x

-16\geq-4x

Step 2:

Next we have to eliminate -4 which is in multiplication with x on the right side.

So applying opposite operation of multiplication that is dividing both sides by -4.

We have to consider here that when we divide or multiply with a negative the sign of inequality reverses, that is ≥ becomes ≤ and vice versa.

\frac{-16}{-4}\leq x

x≥4

Answer is last option x≥4.

The life of a manufacturer's compact fluorescent light bulbs is normal, with mean 12,000 hours and standard deviation 2,000 hour
vitfil [10]

Z value is a numerical  measurement that describe a value relationship to the mean of a group of values. The standard deviations is 1.25 above the mean is 14,500 hours.

<h3>Given information-</h3>

The mean for the bulb is 12,000 hours.

The standard deviation for the bulb is 2000 hours.

Sample value is 14500.

To find out the how many standard deviation is 14500 mean away from the mean the z value of the mean should be calculated.

<h3>Z value</h3>

Z value is a numerical  measurement that describe a value relationship to the mean of a group of values. Z value is the ratio of the difference of the sample value x and mean \mu to the standard deviation. Thus the z value for the given mean \sigma is,

z=\dfrac{x-\mu}{\sigma}

z=\dfrac{14500-1200}{2000}

z=1.25

Thus the standard deviations is 1.25 above the mean is 14,500 hours.

My name is Ann [436]

Answer:

Second choice: 115.44

Step-by-step explanation:

You would want to subtract 253.33-23.33-25.09-33.45-56.02 to get the answer.

There are multiple ways you can do it, first way is to add all the numbers together to get 23.33+25.09+33.45+56.02=137.89

Then, do 253.33-137.89 to get 115.44.

The second way is to manually subtract them one by one from 253.33 to get the same result: 115.44.
