Step-by-step explanation:
Please see attached picture for full solution.
Answer:
the answers are: b, c, and e
Step-by-step explanation:
since line m is pointing down, the slope is negative
since line n is pointing up, the slope is positive
since line m's y intercept is 2, and line n's intercept is -3, and 2 is greater than -3, the y intercept for line m is greater than that of line n
Answer:
Step-by-step explanation:
The absolute value is 62/3
Answer:
0.903264
Step-by-step explanation:
Given that a TV set contains five circuit boards of type A, five of type B, and four of type C. The probability of failing in its first 5000 hours of use is 0.03 for a type A circuit board, 0.04 for a type B circuit board, and 0.03 for a type C circuit board.
Let A' = the event that A fails, B' = B fails and C'= C fails.
Probability that no circuit board fails = Prob (A'B'C')
= P(A')P(B')P(C') (since A,B, C are independent, their complements are independent
= (1-0.03)(1-0.04)(1-0.03)
= 0.903264
