<h3>arithmetic mean</h3>
The arithmetic mean of a set of numbers is their sum, divided by the number of numbers. It is sometimes represented by the Greek letter μ or a variable with an overbar.
<h3>geometric mean</h3>
The geometric mean will be the n-th root of the product of n numbers.
<h3>harmonic mean</h3>
The harmonic mean is the reciprocal of the arithmetic mean of the reciprocals.
<h3>proportion</h3>
In a proportion written as ...
a/b = c/d
The two values closest to the middle of the expression (b and c) are called the "means". Those farthest away (a and d) are called the "extremes". It is said that ...
the product of the <em>means</em> is equal to the product of the <em>extremes</em>
Answer:
x = log 2.97/log 1.13
Step-by-step explanation:
That would be ;
1.13^x = 2.97
Take the log of both sides
log 1.13^x = log 2.97
x log 1.13 = log 2.97
x = log 2.97/log 1.13
Price of gallon of gasoline one year ago is $ 4.1
<em><u>Solution:</u></em>
Given that you pay $ 3.69 for a gallon of gasoline
This is 90% of the price of a gallon of gasoline one year ago
To find: price of a gallon of gasoline one year ago
We can solve this sum by setting up proportion
Let "x" be the price of gallon of gasoline once year ago
By proportions we get,
Thus price of gallon of gasoline one year ago is $ 4.1
Method 2:
you pay $ 3.69 for a gallon of gasoline
Let "x" be the price of gallon of gasoline once year ago
3.69 = 90% of the price of a gallon of gasoline one year ago
3.69 = 90 % of x
Thus price of gallon of gasoline one year ago is $ 4.1
