The answer is : -3/7

You move the terms so it looks like: 4x = 11x + 3

Then you collect like terms so you should have -7x = 3

After that just divide both sides by -7x and x should equal -3/7

Answer:

$x=-\frac{3}{7}$

Step-by-step explanation:

$4x-3=11x\\\\4x-3+3=11x+3\\\\4x=11x+3\\\\4x-11x=11x-11x+3\\\\-7x=3\\\\\frac{-7x=3}{-7}\\\\\boxed{x=-\frac{3}{7}}$

Hope this helps.

What does the frequency column in the attached table sum to?
What does the relative frequency column in attached table sum to?
What is the difference between relative frequency and frequency for each data value in the attached table?
What is the difference between cumulative relative frequency and relative frequency for each data value in attached table?

The correct answers are

65
1
The relative frequency gives the relative proportion of each frequency in the sample while
The frequency is the observed number of count of each grouping has in a given sample size

Step-by-step explanation:

1. The frequency column in the attached column sums up to 65 because it is the total number of sales persons selected

2. The relative frequency column in the attached table sum up to 1 because it is the sum of the fractions of the individual frequencies to the total frequency

3. The difference between relative frequency and frequency for each data value is that

The relative frequency gives the relative proportion of each frequency in the sample while

4. The frequency is the observed number of count of each grouping has in a given sample size
