Answer:
The median because it is unaffected by outliers.
Step-by-step explanation:
While mean is one of the most well known and used central tendency measurements, it has some weaknesses. Mean will show inaccurate data if there are outliers that have a very huge/small value. Income is one of the things that can hugely vary among people. A billionaire can pull the data up and make the mean show result that higher than it should be. In this case, the median is better to show the data. The mode is used for nominal data, while income is ordinal.
Answer:
B
Step-by-step explanation:
10% of 49.99
0.1 x 49.99 = 4.99
49.99 - 4.99 = 45.00
30% of 60.00
0.3 x 60 = 18
60 - 18 = 42.00
Taking 4 out from first two terms, we will get
Now we divide the coefficient of x by 2 and add and subtract the square of the result, we will get
Distributing 4
Cancelling 9
And that's the required standard form.
