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 :)
Explanation:
no it's you know for getting them for this
Answer:
The molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate into 355 mL of water is 0.9881M
Molarity of solution is the ratio of the number of moles of the substance to the volume.
n is the number of moles of the compound
Mass of calcium nitrate = 54.3g
Molar mass of calcium nitrate = Ca(NO₃)₂ = 164.088 g/mol
Get the required molarity;
Hence the molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate into 355 mL of water is 0.9881M

Answer:
A) stratified
Explanation:
Total call including 6500 'yes' and 4100 'no' are 10600 and on each call there was a fifty cent charge. Total charge becomes 5300 $ so this is very straight forward data. And from this test two types of classes are made with cleared population in each class and such cleared population division is example of stratified sampling so this is right answer.
