Ok so
sale is 15% off
and add 6% tax
100-15=85
100+6=106
therefor
1250 with 15% discount plus 6% tax means
1250 times 85% times 106% =
1250 times 0.85 times 1.06=1126.25
final cost=$1126.25
The distribution shape that tells us for which it is best to use the mean is the skewed.
<h3>What is the mean?</h3>
This is the term that is used to refer to the average score that exists in a data set.
In the question, these are the reasons why the other options are not correct
When we say Bimodal we are talking about the 2 modes that are in a symmetric distribution. This has nothing to do with the mean
The bell shape has to do with how the normal distribution is when it is drawn. It would create a bell shape hence the mean is not useful.
symmetric has to do with the fact that there are mirror images when the vertical line is drawn in the distribution.
Uniformed shapes tells us that the classes are made up of the same frequency all through.
The skewed shape is what tells us if the median is more or if it is less.
Hence we have the answer that the distribution shapes for which it is most often appropriate to use the mean is the skewed.

Answer:
471.24
Step-by-step explanation:
The formula for circumference is 2×pi×r. Replace the r with 75 and multiply.
Answer:
Standard deviation of the weight over a day is 1.15
Step-by-step explanation:
Since it is given that water weight is uniformly distributed between -2 to 2.
So applying formula for variance of uniformly distribution as follows,
From the given data, values of a and b is , 
, 
..
Substituting the values,
Now, 
Dividing the fraction by 4,
So, the value of variance is 
The formula for standard deviation is given as,
Substituting the value,
Rounding to 2 decimal places,
So, the value of standard deviation is 1.15.
