d. The mean is much smaller than the median.

Answer: c. The mean is much larger than the median
Step-by-step explanation:
A dataset is skewed to the right when the peak of the dataset is located in the left( left of the mean), and it has a long right tail. It is also call positive skewed distribution. One of the characteristics of right skewed dataset is that the mean of the dataset is always greater/larger than the median and mode.
Therefore, for the case above if the mean is much larger than the median, it indicates that the dataset is skewed to the right.
A dataset is skewed to the right when the mean is much larger than the median. Therefore, the correct answer is option c.
When a dataset is skewed to the right, it means that the distribution of data is not symmetric, and it is stretched out more towards the higher values (right side) than the lower values (left side). This can be due to the presence of outliers or a natural characteristic of the data.
Now, let's look at why option "c" indicates right skewness:
c. The mean is much larger than the median.
The mean is the arithmetic average of all the values in the dataset, while the median is the middle value when the data is arranged in order. When a dataset is positively skewed (skewed to the right), it means that there are some significantly larger values in the right tail of the distribution that pull the mean to the right (towards higher values).
In this situation:
The mean gets pulled toward the larger values because the larger values have a greater impact on the mean due to their magnitude.
The median remains closer to the bulk of the data because it is not affected by extreme values as much as the mean.
So, when the mean is much larger than the median, it is an indication that there are significant outliers or a longer right tail in the dataset, which is a characteristic of a right-skewed distribution.
Therefore, the correct answer is option c.

The least and greatest weights of the potatoes in the data set are 1/8 and 3/4 respectively.
How to find the least and greatest weight?
The weight of the potatoes are:
- 1/4 = 0.25
- 3/8 = 0.375
- 5/8 = 0.625
- 1/2 = 0.5
- 3/4 = 0.75
- 1/8 = 0.125
Therefore, the least weight of the potatoes is 1/8 equivalent to 0.125
The greatest weight of the potatoes is 3/4 equivalent to 0.75

ok 8 * 7 = 56 but your trying to break apart so ..
So ur trying to break apart 7 and 8 to still get ur sum 56 , so first , we are going to break up 8 which is 4 ... so we have 4 and 4 cause 4 +4 = 8 , then we look at 7 .... you see , there is no way you can break up 7 from a lower number value . so im going to keep 7 as it is cause f you noticed....8 is split equally with 4 , but when you look at 7 , there is no way at all that you can equally split 7 so im going to solve this problem , how we have it is
4 + 4 = 8 * 7 = 56
makes sense cause you add 2 4's cause 4 + 4 = 8 the n u times 7 with the answer of 4 + 4 and you got your answer
Break method ...
8 - 4 = 4
7 = ? < no equal splitting
4 + 4 = 8 * 7 = 56

Thus
the ratio of those numbers that do contain a 3 over the total is equal to
therefore
the answer is
In the first 100 -> 100 - 9 * 9 = 19 (contain a 3).
In the first 10^n -> 10^n - 9^n (contain a 3).
The answer is 3.439 numbers contain a 3 in the first 10.000
