Assuming the plumbing pipe is PVC, the answer would be nonmetal
PVC or polyvinyl chloride has a chemical formula of (C2H3Cl)n. From the element, we can see that the polyvinyl chloride is made from carbon, hydrogen, and chloride. There are no elements that belong to the metal group or metalloid group, so the plumbing pipe would be nonmetal.
The following answers:
1. B
2. D
Answer:
a) 12/323
b) 8/233
Explanation:
a) The probability of a red ball being drawn is 12/38, or in a simplified fraction, 6/19. To find the probability that 3 are red you would multiply the probability of the fraction for each, except subtracting one from the total each time as the drawn is done without replacement. This is done as follows: 6/19 × 6/18 × 6/17= 12/323
b) The probability of drawing a blue ball is 8/38, or 4/19. To find that the first one is blue and the rest are red, the equation is done as follows: 4/19 × 6/18 × 6/17 = 8/233

sorry but I need some three point so that's why I didn't
The first scientist to show that atoms emit tiny negative particles was J. J. Thomson.
