Difference between np hard and np complete?
All NP complete problems are NP hard problems when solved in a different way. But, all NP hard problems are not NP complete. Ex: 1. Traveling salesman problem. It is both NP hard and NP complete. We can find that whether the solution is correct or not in the given period of time. In this way, it is NP complete. But, to find the shortest path, i.e. optimization of Traveling Salesman problem is NP hard. If there will be changing costs, then every time when the salesperson returns to the source node, then he will be having different shortest path. In this way, it is hard to solve. It cannot be solved in the polynomial time. In this way, it is NP hard problem. 2. Halting problem. 3. Sum of subset problem.
Is -225.4 a rational number?
Yes
If the original price of a computer was reduced by 250 dollars and the new discounted price is 1499 dollars what was the original price of the computer?
$1749 RP-DA = NP where RP is regular price minus discount amount (DA) is equal to New price (NP) Change the formula to solve for RP you get NP + DA = RP 1,499 + 250 = RP 1,749 = RP The Regular price was one thousand seven hundred and forty nine
What is the mean variance and standard deviation for the number of heads when 20 coins are tossed?
mean = np = 20*0.5 = 10 Variance = npq = 20*0.5*0.5 = 5 Std dev = sqrt(npq) = sqrt(20*0.5*0.5) = 2.23
How can you approximate a binomial distribution to a poison distribution when the number of binomial trials became large enough?
The Poisson distribution with parameter np will be a good approximation for the binomial distribution with parameters n and p when n is large and p is small. For more details See related link below
What is the missing number in the nuclear reaction shown below 237 93 Np - 4 2 He plus 233 Pa?
91
What element is formed when neptunium desintegrates?
Neptunium-237 decay to protactinium-233.Other isotopes of Np decay to other daughter isotopes.
What element is formed when neptunium atoms fall apart?
For the most common isotope of neptunium, Np-237, the decay daughter is protactinium-233.Each isotope has another type of decay.
What element is Np?
The element with chemical symbol Np is Neptunium. Neptunium is a radioactive Lanthanide and is part of the unofficial Promethium family. It has 93 electrons in 7 shells and is next to Uranium and Plutonium.
Neptunium's only naturally occurring isotope 237 93Np decays by emitting one alpha particle one beta particle and one gamma ray What is the new atom formed from this decay?
Neptunium 237 is not a natural occurring isotope; all the isotopes of neptunium are artificially obtained. The new isotope formed by decay of Np 237 is protactinium 233.
What type od decay does Am-241undergo to become Np-237?
alpha
What is the decay products of americium 241?
The decay product of Am-241 is Np-237.
What type of decay does Am-241 undergo to become Np-237?
The decay that occurs for Am-241 to become Np-237 is called alpha decay. Alpha decay is characterized by a decrease of 2 in the atomic number and 4 in the mass number.
What element has the atomic number 93?
neptunium-NP
What is the equation of decay for americium 241?
Emitting alpha particles Am-241 decay to Np-237.
What is the product of alpha decay for americium -241?
The intermediate product is neptunium 237 ( a very long-lived radioisotope).
What is the first transuranium element?
Transuranium elements are those that have an atomic number greater than uranium's, which is 92. The first transuranium element is neptunium (Np) with atomic number 93.
