An appropriate model is a quadratic, y=0.999x²-1.999x-3.

The r² value is 1, so it is a perfect fit.

Answer:

The required quadratic regression model is y=x^2-2x-3.

Step-by-step explanation:

The given data points are (-1,0), (1,-4), (2,-3), (4,5), (5,12). Plot these points on a coordinate plane.

From the graph it is clear that the given data forms a U-shaped curve. It means we have to find the quadratic regression model.

The general form of quadratic regression model is

y=ax^2+bx+c

Using technology we get,

a=1,b=-2,c=-3

The required quadratic regression model is

y=x^2-2x-3

Therefore the required quadratic regression model is y=x^2-2x-3.

How to explain how to plot the points P(4,10) and Q(9,3) in a coordinate plane?
SpyIntel [72]
Firstly, this is the most important thing to know (x,y). This means that you plot the first number in the x axis and the second number in the y axis. For example, (4,10). You would plot the 4 on the right side of the x axis and you would plot the 10 all the way at the top in the y axis.

Answer:

32

Step-by-step explanation:

<em>The ray created by line BC has two </em><u><em>180° sides</em></u><em>. Side </em><em>AC</em><em> intersects this ray and forms two angles. We can find this second angle by subtracting </em><em>148 </em><em>from </em><em>180 </em><em>to get </em><em>32</em><em>.</em>
