A=148°
B=148°
Step-by-step explanation:
180-38=148°
because A and B are equal, they're both 148°
A) 15/4 = 4/4+4/4+4/4+3/4= 3 3/4
B)9/2= 2/2+2/2+2/2+2/2+1/2= 4 1/2
c = 26/12 = 12/12 + 12/12 + 2/12 = 2 2/12
d) 20/6 = 6/6 + 6/6 + 6/6 + 2/6 = 3 2/6
Answer:
The answer to this problem is 89.
Answer: 0.12
Step-by-step explanation:
The expected number of accidents is a weighted average of the potential number of accidents and their probabilities:
= (0 * 0.935) + (1 * 0.03) + (2 * 0.02) + (3 * 0.01) + (4 * 0.005)
= 0.12
The thickness of the board was decreased from 3 / 4 inches to 9 / 16 inches.
Therefore,
So the board's thickness in inches decreased by
