The answer is B.
in the original equation, CH4 + O2 → CO2 + H2O, there are:
REACTANTS: 2 carbon, 4 hydrogen, 2 oxygen
PRODUCTS: 2 carbon, 2 hydrogen and 1 oxygen.
If we change the equation to this,
CH4 + 2O2 → CO2 + 2H2O, then there are now:
REACTANTS: 2 carbon, 4 hydrogen, 4 oxygen
PRODUCTS: 2 carbon, 4 hydrogen, 4 oxygen
and thus the equation is balanced
your answer for each would be the factor of whatever ur answer is for example 10 times 1.5 is ur first then so on and so forth
Answer:
e)$141,750
Step-by-step explanation:
Let be
AG = Members with advanced degrees
BG = Members with a bachelor's degree
DG = Members with a no degree
In a sample of 50 members it is expected a total of members for every group as follows
For AG = 30 * 0.5 = 15
For BG = 50 * 0.5 = 25
For DG = 20 * 0.5 = 10
The expected donation for every group would be the number of members by the 5% of their incomes
For AG = 15 * 0.05 * $75,000 = $56,250
B For G = 25 * 0.05 * $54,000 = $67,500
For DG = 20 * 0.05 * $36,000 = $18,000
Total donation is the sum = $141,750
