Answer:
After 200 days of work, you would finally get 20 dollars a day for the second job. So, if you are working less than 200 days than the first job. If working more, 400 days could get you 40 dollars a day. I would choose the first one, since by the time you get to 20 dollars, you will have 4000 dollars.
Step-by-step explanation:
Planning, designing, gathering data, analyzing, creating relevant interpretations, and publishing the research findings are all statistical approaches that go into conducting a study.
The statistical analysis lends meaning to the abstract numbers, giving the data some life. Only when appropriate statistical tests are applied will the results and inferences be accurate. Science's field of statistics deals with gathering, organizing, analyzing, and extrapolating data from samples to the entire population. This necessitates the use of an acceptable statistical test, an adequate study design, and an appropriate study sample selection. However, if we want additional information about these, a consulting company may be able to assist us. we will benefit more from Silver Lake Consulting for our project.

It should have 3 solutions.
The number of solutions depends on the term with the highest exponent.
So, in this case we have a cubic equation, there are 3 solutions.
If we have a quartic equation (4th power), there should be 4 solutions.
You can draw both lines y=-7x+12 and y=-2/3x –2/3 and define which part of the plane satisfies the unequalities y ≤ –7x + 12 and y ≤ –2/3x –2/3. For example, choosing point (0,0) you can see that
0 ≤ –7·0 + 12 (is true) and 0 ≤ –2/3·0 –2/3 (is false). This means that (0,0) is a solution of the first unequality and isn't a solution of the second unequality, hence (0,0) belongs to the shaded part of the plane defined by the first unequality and doesn't belong to the shaded part defined by the second unequality. Both (black on the image) parts intersect and the common area (red on the picture) is the <span>region that describes the solutions of the system of inequalities.</span>
