8 1/3% of Jar B’s marbles need to be moved to jar A to make them equal. This is because:
If Jar A has 100 marbles and B has 120 marbles which is 20% more than Jar A then 10 marbles would have to be moved from Jar B to Jar A. To calculate the percentage it would be 10/120 which reduces to .0833 repeating or 8 1/3%.
Hope this helps :)
The number of six samples that could belong to the same population is equivalent to six.
Option A is the correct answer.
<h3>What is the standard deviation?</h3>
The standard deviation is the indicator to determine the variation between the set of amounts as given in the statistical information.
The population is referred to as the entire information being prescribed in data relating to any concept. If the number of samples in a population is 10, then the samples in the same population will also be 10. This shows the number of samples is always equal to the samples in the same population.
Therefore, the six samples belong to the same population comprising of six samples having varied standard deviations.

Answer:
what chemicals are the sun made of
Like any star in its prime, the sun consists mainly of hydrogen atoms fusing two by two into helium, unleashing immense energy in the process. But it's the sun's tiny concentration of heavier elements, which astronomers call metals, that controls its fate.
Explanation:
The oxidation number if eah of the elements is as follows;
- Oxidation number of Mn is + 7 on the right hand side and +4 on the right hand side
- Oxidation number if hydrogen is +1 on both sides
- The oxidation number of oxygen is -2 on both sides
- The oxidation number of sulfur is -2 on the lefthand side and zero on the right hand side.
<h3>What is a redox reaction?</h3>
A redox reaction is one in which there is a change in the oxidation number of the reactants from left to right.
Let us now consider the oxidation number of each element from left to right;
- Oxidation number of Mn is + 7 on the right hand side and +4 on the right hand side
- Oxidation number if hydrogen is +1 on both sides
- The oxidation number of oxygen is -2 on both sides
- The oxidation number of sulfur is -2 on the lefthand side and zero on the right hand side.
