6/3 = 2
The current value of the precious metal is $144/oz
-First, you'd want to determine the original value per ounce since that's what the final unit being asked for is.
- Since the original value of the half ounce piece is given, this first step is fairly simple. You just double ninety.
- We now know that the metal was worth $180/oz when the museum first received it.
- We need to determine the current price of the metal now that is has had a twenty percent loss of value.
- My favorite way to factor in 20% is simply to divide by five since it's a lot more simple than finding the ratio of x$/1%
- $180/5=$36
- Thirty-six dollars is the price drop over the course of the museum possessing the precious metal.
- You now take $180-$36=$144
Answer:
Standard error
Step-by-step explanation:
Standard error: In statistics, the term standard error is also denoted as SE, and is reffered to as the estimate of a particular parameter.
It is defined as the standard deviation in statistics related to its sampling distribution or else the the standard deviation's estimate.
Therefore, if a particular parameter or statistic is considered as a mean then it would be denoted as the standard error of that mean.
The standard error of an estimate may also be defined as the square root of the estimated error variance √
of the quantity,
=√
In the given question, the appropriate answer would be standard error.
Answer:
-4
Step-by-step explanation:
-1.5 (4-r)= -12
4-r = 8
