372 is the answer.
(9*6*3)+(10*7*3)=372
I multiplied $15 by 230% and then added my answer(which was 34.5) because subtracting it wasn't an option and got $49.50
12x²-8x-15 should be your answer
The answer is 59.6 because I divided 298 by 5
Hope this helps!!
Answer: F. Statistic, because the data set of salaries of 50 employees is a sample.
Step-by-step explanation:
A parameter gives measure of a characteristic for the entire population where as a statistic gives measure of a characteristic for the subset of population (sample).
Given : The average annual salary of 50 of a company's 800 employees is $54,000.
It means the sample size = 50 and the sample mean salary= $54,000.
i.e $54,000 is giving the measure for mean salary for the sampled 50 employees.
It means $54,000 is a statistic .
Hence, the correct answer is option (F).
