Actually the formula for the area of a triangle is A = 1/2bh.
First step: multiply both sides by 2, to get rid of the 1/2.
2A = bh
Now divide both sides by b.
2A/b = h or h = 2A/b
Answer:
there are 45 people in the group
2/3xA=30
2A=30x3
A=90/2
A=45
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
