Answer:
D. 48
Step-by-step explanation:
In the experiment, 16/40 landed exactly on heads. If you do 16/40 * 3/3 = 48/120.
This means that you can estimate 48 of the next 120 trials have 2 coins showing heads.
Your answer id D
Hope this helps :D
Given:
The figure of a trapezoid.
To find:
The image points of the given figure after rotation of 180 degrees.
Solution:
From the given figure, it is clear that the vertices of the trapezoid are W(-4,2), X(-3,4), Y(-1,4), Z(0,2).
If a figure is rotated 180 degrees about the origin, then
Using this rule, we get
Therefore, the image points are W'(4,-2), X'(3, -4), Y'(1, -4), Z'(0, -2). So, the correct option is 1.
