Answer:
The median and IQR
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Using the sine ratio in the right triangle.
sinC = 
= 
= 
, thus
∠ C = 
( ) ≈ 34.85° ( to 2 dec. places )
Answer:
They lose about 2.79% in purchasing power.
Step-by-step explanation:
Whenever you're dealing with purchasing power and inflation, you need to carefully define what the reference is for any changes you might be talking about. Here, we take <em>purchasing power at the beginning of the year</em> as the reference. Since we don't know when the 6% year occurred relative to the year in which the saving balance was $200,000, we choose to deal primarily with percentages, rather than dollar amounts.
Each day, the account value is multiplied by (1 + 0.03/365), so at the end of the year the value is multiplied by about
... (1 +0.03/365)^365 ≈ 1.03045326
Something that had a cost of 1 at the beginning of the year will have a cost of 1.06 at the end of the year. A savings account value of 1 at the beginning of the year would purchase one whole item. At the end of the year, the value of the savings account will purchase ...
... 1.03045326 / 1.06 ≈ 0.9721 . . . items
That is, the loss of purchasing power is about ...
... 1 - 0.9721 = 2.79%
_____
If the account value is $200,000 at the beginning of the year in question, then the purchasing power <em>normalized to what it was at the beginning of the year</em> is now $194,425.14, about $5,574.85 less.
If we have two sides equal each other, then we called the statement "equation"
Example:
2x + 3 = 5x - 2 is called an equation
2x + 3 is an algebraic expression
5x - 2 is an algebraic expression
When we put = sign between them, they called an equation
Then when two equal signs are placed between two algebraic expressions, they formed an equation
The answer is an equation
