Answer:
Independent event
Step-by-step explanation:
Independent event is defined as events that will not influence each other. In this question, the combination lock has three separate wheels. Each wheel has one key out of 10 possible numbers. The key of the first wheel will not influence the number pool of second and third wheels. All of the wheels will have 10 possible numbers regardless. Therefore, the combined number is an independent event.
The ration is 28:1 and 11:7
The coordinates of trapezoid vertices are:
- J(-7,-2);
- K(-4,-2);
- L(-2,-5);
- M(-9,-5).
The translation rule is
(x,y)→(x-2,y+8).
Then the image trapezoid vertices are:
- J'(-7-2,-2+8) that is J'(-9,6);
- K'(-4-2,-2+8) that is K'(-6,6);
- L'(-2-2,-5+8) that is L'(-4,3);
- M'(-9-2,-5+8) that is M'(-11,3)
