Step-by-step explanation:
-4x + 3 < 23
-4x < 20
x > -5
hmm,I don't think we need to put equal sign instead of (<) , for when we started calculating.
we can just keep the question as it is and calculate.
Answer: you’re multiplying by 2 each time
Answer:
The best choice would be hiring a random employee from company A
Step-by-step explanation:
<em>Supposing that the performance rating of employees follow approximately a normal distribution on both companies</em>, we are interested in finding what percentage of employees of each company have a performance rating greater than 5.5 (which is the mean of the scale), when we measure them in terms of z-scores.
In order to do that we standardize the scores of both companies with respect to the mean 5.5 of ratings
The z-value corresponding to company A is

where
= mean of company A
= 5.5 (average of rating between 1 and 10)
s = standard deviation of company A

We do the same for company C

This means that 27.49% of employees of company C have a performance rating > 5.5, whereas 71.42% of employees of company B have a performance rating > 5.5.
So, the best choice would be hiring a random employee from company A
Answer:
<h2>x = 24</h2>
Step-by-step explanation:

Multiply through by the LCM that's 6 in order to eliminate the fraction
That's

Using the addition property add 2x to both sides of the equation
That's

<u>Divide both sides by 5</u>

We have the final answer as
<h3>x = 24</h3>
