When you have a set of data points and you want to get a model out of it, you do data fitting. The first thing to do is plot the points using a scatter plot type of chart as shown in the picture. I used MS Excel as a tool for data fitting. On the left side of the picture, I used linear fitting. Then, it gives you the linear equation y=0.2907x + 2.2643. It has a correlation coefficient, R^2, of 0.9595. This measures how good your data fits the model equation. The closer it is to 1, the better. However, it is rare to get 1 because that is very ideal. A R^2 of 0.9595 is very satisfactory already. But if you want an even better model, the right side of the picture shows data fitting on a quadratic equation with an equation of y=0.0209x^2 +0.506x+2.0232 with R^2 of 0.9992.

Answer:

The closer this value is to 1 or -1, the better the fit. For linear, the correlation coefficient R2=.96.  For quadratic, the R2=.99.  For exponential, the R2=.91.  This means quadratic is the best fit, very good actually since .99 is very close to 1.

Which is not a way to determine if two ratios are proportional?​
AfilCa [17]

Answer:

the correct answer is d

Step-by-step explanation:

To find an equal ratio, you can either multiply or divide each term in the ratio by the same number (but not zero). For example, if we divide both terms in the ratio 3:6 by the number three, then we get the equal ratio, 1:2.

Which statement is the correct interpretation of the inequality –5 > –6? (1 point)
lilavasa [31]

Answer: OPTION D.

Step-by-step explanation:

The symbol of the inequality ">" means "greater than". Then, -5 is greater than -6.

If a negative number -a is greater than other negative number -b , then the distance between -a and zero is shorter than the distance between -b and zero.

You can see in the number line attached that -5 is closer to 0 than -6. Therefore, -5 is located to the right of -6.

Bumek [7]

Answer:

A"fishbone" diagram

Step-by-step explanation:

A"fishbone" diagram, may help to determine potential causes of an issue and organise concepts into valuable groups of brain storming. A depiction of the fishbone is a graphical way of looking at causes and effects.

It's a more organised solution than other brain storming tools that cause problems. The issue or effect is shown on the fish's head or mouth.
