A box contains 9 new light bulbs and 6 used light bulbs. Each light bulb is the same size and shape. Meredith will randomly select 2 light bulbs from the box without replacement. What is the probability Meredith will select a new light bulb and then a used light bulb

Answers

Answer 1

Answer:

(9/35) = 0.257

Explanation:

Box contains 9 new light bulbs and 6 used light bulbs, total number of bulbs = 15.

Probability of selecting two bulbs; a new light bulb and then, a used light bulb in that order = [(probability of selecting a new bulb) × (probability of selecting a used bulb from the rest)] = [(9/15) × (6/14)] = (9/35) = 0.257

Answer 2

Answer:

Final answer:

The probability that Meredith will select a new bulb and then a used bulb in sequential order without replacement is around 26%.

Explanation:

The question asks about the probability of selecting a new light bulb and then a used light bulb from a box containing 9 new light bulbs and 6 used light bulbs. Probability events like these are solved using multiplication rules of probability that each event is independent.

First, the probability of picking a new bulb is 9/15 (total bulbs are 15). If you pick one out, you don't replace it, so there are only 14 bulbs left. Thus, the probability of picking a used bulb now is 6/14. Hence the probability of both events happening in order is the multiplication of both, i.e., (9/15)*(6/14) = 54/210 = 0.257 or around 26%.

Air is made of 80% nitrogen and 20% oxygen by volume. The densities of air and oxygen is 1.29kgm^-3 and 1.43kgm^-3 respectively. What is the density of nitrogen? Please specify your soultion,thank you!

Answers

Volume % = mole %

Molar mass of oxygen = 32kg/kmol

Molar mass of nitrogen = 28 kg/kmol

Density of nitrogen = Density of oxygen x molar mass of oxygen x molar ratio of air x molar mass of nitrogen

Density of nitrogen = (1.43kgm^-3)(1 kmol O2/32 kg O2)(80 kmol N2/ 20 kmol O2)(28 kg N2/1 kmol O2) = 5.01 kg/m3

Could a vector ever be shorter than one of its components? Equal in length to one of its components? Explain.

Answers

It can never be shorter than a component - magnitude of a vector is the square root of the sum of the components squared, and a square function never produces a negative number. However, it can be the same size as it's component, if that component is the only one.

Answers

The correct answer for the question that is being presented above is this one: "b. Environmental physician, environmental veterinarian." The groups of environmental science careers that are most similar is that of Environmental physician and environmental veterinarian.

Correct answer choice is:

B. Environmental physician, environmental veterinarian.

Explanation:

Environmental medicine is a field involving several academic disciplines including physicians, environmental science, chemistry and many other related fields, protruding with environmental diagnostics. The extent of this domain includes examining the interplay's between ecosystem and human health, and the role of the atmosphere in producing or negotiating infection. Likewise, In the wildlife division, doctors are frequently defied with the outcomes of environmental contaminants and contagious infection disorders that probably endanger wild and housebroken animals as well as individuals.
