Answer:

Step-by-step explanation:

see attached image

<u>shaded area = total area (1) - unshaded triangular area (2)</u>

1. area of a trapezoid = (a + b) * h/2

where a = 8, b = 18, h = 15

Area of trapezoid = (8 + 18) * 15/2 = 195 ft²

2. Area of unshaded triangle = 1/2 (8) 15 = 60 ft²

shaded area = 195 - 60 = 135 ft²

The location of the vertex tells you the horizontal and vertical shift. (The parent function f(x) = x² has its vertex at the origin, (0, 0). The vertical distance of the point 1 unit left or right of the vertex in relation to the vertex tells you the vertical scale factor (stretch).

g(x) = f(x +3) -3
horizontal shift left 3
vertical shift down 3

h(x) = -3f(x)
reflection across the x-axis
vertical stretch of 3

d(x) = f(x -3) -3
horizontal shift right 3
vertical shift down 3

The answer is A: A uniform probability model is a good model to represent probabilities related to the numbers generated in Pedro's experiment.

and B: It is likely that the spinner is fair.
