Answer: 1)The drivers with low alcohol in take from the breathlyser, being above the limit, A = 5/100;
2)The drivers above the alcohol limit, give reading below that level, B = 15/100;
3) The drivers above the alcohol limit that are arrested at radom by police, C = 12/100
Step-by-step explanation: a) A + B + C = 5/100 + 15/100 + 12/100 = 32/100
b) 1 - ( A + B + C) = 1 - 32/100 = 68/100
c) A = 5/100
d) 1 - 5/100 = 95/100
Answer:
(4,1)
Step-by-step explanation:
point b is at (-1, 4) and the rule for 90 degree clockwise rotations is (y, -x) so it's (4, 1)
first subtract the last equation from the first. this gives:-
-x + y = -8 .....................(1)
Then multiply the first equation by 2 and add it to the 2nd equations This gives
9x = 18
so x = 2
and from equation (1) y = -8 + 2 = -6
Substituting for x and y in the second equation
z = (24 -5(2) -12) / 2 = 1
Answer is choice b.
