Answer:
Both statements (1) and (2) TOGETHER are sufficient to answer the question asked; but NEITHER statement ALONE is sufficient.
Step-by-step explanation:
Solving the equation of statement (1) with the quadratic formula:
In this equation, one of the values of x is bigger than -20 but the other is smaller, this statement doesn't give enough information to answer the question.
Solving the quadratic equation of the statement (2):
Again, one of the values of x is bigger than -20 and the other is smaller than -20. But if the information of this statement is considered along with the other x must be equal to -23, that is the value that appears as an answer in both equations, and with this information is possible to answer the question.
Answer:
b:not similar
Step-by-step explanation:
Answer:
0.35
Step-by-step explanation:
Total rolled = 360 times
Two rolled = 59
Three rolled = 67
Two rolled probability = 59/360 = 0.164
Three rolled probability = 67/360 = 0.186
The experimental probability of rolling a two or a three
==> Two rolled probability + Three rolled probability
==> 0.164 + 0.186
==> 0.35
