Step-by-step explanation:
20/5=4, 100/25=4, 4/1=4, and 60/15=4
From the given discrete distribution, we have that:
<h3>What are the mean, the variance and the standard deviation of a discrete distribution?</h3>
- The mean of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.
- The variance is given by the sum of the difference squared between each observation and the mean, divided by the number of values.
- The standard deviation is the square root of the variance.
In this problem, the distribution is:
Hence, the mean is:
The variance is:
The standard deviation is:

Answer:
12%
Step-by-step explanation:
There are a total of 175 units in an apartment complex.
Out of which, 154 units are occupied.
Now, we have to find the percentage of the apartment which are unoccupied.
So, the number of units that are not occupied is (175 - 154) = 21.
Hence, the percentage of the number of unoccupied units of the apartment complex will be (Answer)
Answer:
D. The mean debt of all students and the proportion holding student loans are both parameters, but the values 30% and $18,450 are statistics.
Step-by-step explanation:
Parameters and statistic are numerical characteristic derived form out data. The distinction between both are : paatwrs are numeric characteristic which are calculated from the population data while those obtained form the sample. Data are called statistic.
The 30% and mean of 18450 are derived from the sample data.
However, the proportion of all students holding a student loan and the mean value is $18450.
As all students represents the total population.
first day is 5; second day is the square of 5, so it's 25; third day is the 3 times of the second day, so it's 25x3, which is 75. Add these 3 days together to get the answer, which is 105 dollars.
