Answer:

1: The formation of elements heavier than iron and nickel requires the input of energy. Supernova explosions result when the cores of massive stars have exhausted their fuel supplies and burned everything into iron and nickel. The nuclei with mass heavier than nickel are thought to be formed during these explosions.

Explanation:

2: The more luminous they are, the more reactions are taking place in their cores. Massive stars live shorter lives than the common small stars because even though they have a larger amount of hydrogen for nuclear reactions, their rate of consuming their fuel is very much greater.

The author makes this claim in the passage: Keeping animals in zoos is cruel and unfair to the animals.

The author supports this claim by discussing three major problems with zoos. The first problem is that zoos cause behavior problems in animals. The author supports this claim by mentioning studies that prove the claim. The author also states that zoos do not consider the specific traits of different animals. The author cites a study of a zoo in Belfast, Ireland, to support this claim. Lastly, the author states that zoos do not focus on protecting endangered animals. The author supports this claim by noting the number of zoos worldwide that support wildlife conservation.

Read two numbers from user input. Then, print the sum of those numbers. Hint -- copy/paste the following code, then just type co

pantera1 [17]

The code that read two numbers from user input, then, print the sum of those numbers are as follows:

x = int(input("write a number: "))

y = int(input("write another number: "))

print(x + y)

<h3 /><h3>Code explanation</h3>

The first line of code ask the user for a number input. The integer input is stored in a variable x.

The second line of code ask the user for another number input . The integer input is stored in a variable y.

Finally, we print the sum of the user's input.

About % of the population of a large country is. If two people are randomly selected, what is the probability both are ? what

mezya [45]

Using the binomial distribution, it is found that there is a:

0.0036 = 0.36% probability that both are allergic to pollen.

0.1164 = 11.64% probability that at least one is allergic to pollen.

<h3>What is the binomial distribution formula?</h3>

The formula is:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$C_{n,x} = \frac{n!}{x!(n-x)!}$

The parameters are:

x is the number of successes.

n is the number of trials.

p is the probability of a success on a single trial.

Researching the problem on the internet, it is found that:

6% of the population is allergic to pollen, hence p = 0.06.

Two people are chosen at random, hence n = 2.

The probability that both are allergic is P(X = 2), hence:

P(X = 2) = 0.06^2 = 0.0036.

0.0036 = 0.36% probability that both are allergic to pollen.

The probability of at least one is:

P(X >= 1) = 1 - P(X = 0) = 1 - 0.94^2 = 1 - 0.8836 = 0.1164.

0.1164 = 11.64% probability that at least one is allergic to pollen.
