Answer:
C. $7.70
Step-by-step explanation:
First, you have to calculate the 10% of the price and subtract that from the price to find the amount of the discount:
$27*10%=$2.7
Now, you can add the amount of the discount plus the coupon to find the amount that the customer saved:
$5+$2.7=$7.7
According to this, the answer is that the customer saved: C. $7.70
That's really hard homework I really have never seen anything like that but I'll ask my sister.
Solution: For a positively skewed distribution with a mean of m=20, the most probable value for the median is less than 20.
<u>Explanation:</u>
We know that in a symmetric distribution, the relationship between mean, median and mode is:

In case of negatively skewed distribution, the relationship between mean,median and mode is:

In case of positively skewed distribution, the relationship between mean,median and mode is:

Therefore, for a positively skewed distribution with a mean of m = 20, the median would be less than Mean. Hence the probable value of median is less than 20
