Answer:
41. 1/144
42. 6
44. C
45. D
Step-by-step explanation:
41. Chance of rolling one twelve is 1/12. Then, the chance of rolling 2 is 1/12*1/12 = 1/44
42. Since there are 25 students in the class, the middle value, 13, will be the median. The 13th number is a 6, therefore, the median is a 6.
44. We know that this is a triangle because 50+50+80=180 (triangle sum theorem). Since this works, by the principles of simular triangles, we can have infinite number the triangles which warrants the solution of more than 1.
45. x is negative so it is less than 0. However, y is greater than OR equal to 0. This means we can have two solutions. z is negative or z is 0.
