Answer:
% change in the cost of electricity for a typical house = 54.55%
Explanation:
A typical house uses 10,900 kWh of electricity per year
Average cost of electricity production from hydroelectric power = $0.05 per kWh
Cost of production of electricity from hydroelectric power in 1 yr= $0.05 * 10900 = $545
Average cost of electricity production from conventional coal-fired power plant = $0.11 per kWh
Cost of production of electricity from hydroelectric power in 1 yr= $0.11 * 10900 = $1199
Change in the cost of electricity due to the switch in power source = $1199 - $545 = $654
% change in the cost of electricity = (654/1199) * 100
% change in the cost of electricity = 54.55%
Answer:
Knowing others is intelligence; knowing yourself is true wisdom. mastering others is strength; mastering yourself is true power. if you realize that you have enough, you are truly rich, "And the cause of not following your heart, is in spending the rest of your life wishing you had."

Explain how to solve the 2020th term
Solve the 2020th term
Solving the 2020th term of a sequence using conventional method may be a little bit difficult but in questions like this, it's not.
The very first thing to do is to solve for the third term;
The value of the third term is the value of every other term after the second term of the sequence; So, what I'll do is that I'll assign the value of the third term to the 2020th term
<em>This is proved as follows;</em>
From the question, we have that "..... each term after the second term is the average of all of the preceding terms", in other words the MEAN

<em>Assume n = 3</em>

<em>Multiply both sides by 2</em>


<em>Assume n = 4</em>


Substitute 



Assume n = 5


Substitute
and 



<em>Replace 5 with n</em>

<em>(n-1) will definitely cancel out (n-1); So, we're left with</em>

Hence,

Calculating 



Recall that
