Answer:

3.803% Profit

Step-by-step explanation:

First let us calculate total sales, then calculate the total cost, and then divide the two.

Sale: 120*1.1=132 and 52*.9=46.8

Cost: 120 and 52

Profit equation:

\frac{Net sales-COGS}{Net Sales} =Profit

\frac{(132+46.8)-(120+52)}{(132+46.8)}

Simplify:

\frac{6.8}{178.8} =.03803 or 3.803% Profit

What are the solutions to the equation<br><br>x^2+14x=-130<br><br>please do a step by step
Serjik [45]

Answer:

The answer to your question is:  x1 = - 7 + 9i      x2 = -7 - 9i

Step-by-step explanation:

                                             x² + 14x = - 130

                                            x² + 14x + (7)² = -130 + (7)²

                                           (x + 7)² = -81

                                            x + 7 = ± √-81

         i² = -1,  then                x + 7 = ±√ 81i²

                                            x + 7 = ± 9i

                          x1 = -7 + 9i                         x2 = -7 - 9i

bearhunter [10]
<span>What is the question?

This is an example of an ideal distribution and statical preview of the sample gathered from the population. 900 samples is a great number considering the central limit theorem of 30.
This distribution could also be described as a mesokurtic and normal form of the statistical model.

Statistics. </span><span>Statistics is a branch of mathematics which is the scientific study of mathematical values pertaining to qualitative descriptions and transcribe them into quantifying values such as the descriptive statistics and infuses these quantities in the field of inferential statistics. In these two categories involve probabilities, distribution and deviations which are mainly compositions of the descriptive statistics. Inferential statistics will involve comparison and variation of the given values. Methods are t-test, analysis of variance, and two-way analysis of variance and other methods. </span>
