Answer:5/6
Explanation:
Each Coin has two possible outcomes heads or tails
if there are 3 coins and two outcomes for each coin you multiply 3 and 2 and that is a total of 6 possible outcomes
Since the question is saying it can't have more than 2 heads we subtract what we don't want with the total possible outcomes
Out of the 6 outcomes how many are there where all of the coins land on heads? Only 1
6-1=5
Out of 6 outcomes 5 of them the coins landed on 2 heads or less
5/6
The reason why iron oxide has more mass than the iron is because Iron oxide has oxygen atoms, and pure iron does not.
When iron rusts and forms iron oxide, the iron oxide has more mass than the iron. Which statement correctly explains this
observation?
(A)Iron oxide has oxygen atoms, and pure iron does not.
(B)The oxygen atoms in iron oxide have more mass than the iron atoms in pure iron.
(C)The iron atoms in iron oxide have more mass than pure iron.
(D)There are more iron atoms in iron oxide than in pure iron.
When a chemical reaction takes place, other atoms are combined with pure elements to form compounds. This addition of another atom (oxygen) after reaction makes iron oxide formed heavier than pure iron.
Iron oxide is a chemical substance formed when pure iron rusts. The formation of iron oxide is a chemical reaction.
Hence, the correct answer to the question is; the iron is heavier because Iron oxide has oxygen atoms, and pure iron does not.

Since the synthesizer is an electronic instrument, oscillation is not a factor in sound generation is a false statement.
<h3>
What is oscillation in sound?</h3>
An oscillation is known to be that which need to be forced of it is in line or in response to an kind of excitation or free vibration.
Hence in the case above, Since the synthesizer is an electronic instrument, oscillation is not a factor in sound generation is a false statement.

Culture and technology have allowed anatomically modern humans to adapt beyond our biological limits.
Culture is what makes us human, and different from animals. We have developed culture over a long period of time, and even though it changed throughout the ages, it is what defines us nevertheless. And obviously technology is advancing the society to an even greater extent.
The exercise is related to the Ratio Test for Convergence. The rules for this kind of test are given below.
<h3>What are the rules for Ratio Test for Convergence?</h3>
The rules are:
- If the limit is less than 1 when conducting the ratio test, your series is definitely convergent.
- The test is inconclusive if the limit is equal to 1.
- The series is divergent if the limit is greater than 1.
Using this knowledge, we are able to state that
- A is not conclusive.
- C's convergence is absolute.
- There is divergence with D and E.
- B and F appear to be employing the nth-term test. The nth-term involves determining the sequence's limit as it approaches infinity.
The nth-term test determines whether a series is divergent if the limit is bigger than 0, thus, both B and F are divergent series.
