2x - (3x + 2x)
= -3x
hope this helps !!
<span> (0, 2) (3, 0)
slope = (2-0)/(0-3) = -2/3
perpendicular lines, slope is opposite and reciprocal
so </span><span>the slope of a line that is perpendicular to the line is 3/2
answer
3/2</span>
Answer:
Step-by-step explanation:
Number of electronic systems = 6
(a) Number of defected systems = 2
Probability of getting at least one system is defective
1 defective and 1 non defective + 2 defective
= (2 C 1 ) x (4 C 1) + (2 C 2) / (6 C 2)
= 3 / 5
(b) four defective
Probability of getting at least one system is defective
2 defective and 2 non defective + 3 defective and 1 non defective + 4 defective
= (4 C 2 ) x (2 C 2) + (4 C 3 )(2 C 1) + (4 C 4) / (6 C 4)
= 1
It will be 150 because if each foot is 30 cm you will count by 3s 5 times and you get 15 and just add the zero and you get 150
