160 was the original price.
We know this because 25% is the same as I think of it as a quarter 25x4=100
So you would have to do 40x4=160
Your welcome.
14 = -(p-8)
Step 1 : Distribute the negative sign. This is equivalent to multiplying each term in the parenthesis by -1.
14 = -p+8
Step 2: Subtract 8 from each side to isolate the -p.
14 - 8 = -p +8 - 8
6 = -p
Step 3: Multiply everything by -1 to get what p is equivalent to.
6 * -1 = -p * -1
-6 = p
Which can be rewritten as
p = -6
Answer:
Is unbiased estimator
Step-by-step explanation:
In statistics, Numerical characteristics derived from population data is referred to as parameter, while those derived from the sample data are called statistic. When a sample is drawn from a particular population, the statistic of such sample could be used as either a point or interval estimate of the population. However, the estimator derived from the sample in most cases isn't equal to the exact parameter value. When this happens, that is, when population parameter equals the estimate of the sample statistic, then we have an unbiased estimator.
