Answer:
Step-by-step explanation:
Basically, if you want to find the probability of getting either outcomes, you will need to subtract the probability of getting neither outcomes in the question. The probability for both outcomes are 7/9 and 5/9 respectively. You will have to multiply to get the probability of getting both of the non-desired outcomes. Hence, it gives the equation above
Answer:
There are 60 different summer reading lists possible.
Step-by-step explanation:
A certain school district has specified 5 different novels and 4 different non-fiction.
Each summer reading list must have exactly 3 novels and 2 non-fiction books.
So, the number of different summer reading lists that are possible is given by:
=
=
Hence, there are 60 different summer reading lists possible.
Answer:
The coefficient of variation for the weight and age are 5.9% and 10.6%.
Step-by-step explanation:
The coefficient of variation (CV) is well defined as the ratio of the standard deviation to the mean. It exhibits the degree of variation in association to the mean of the population.
The formula to compute the coefficient of variation is:
Here σ = standard deviation and µ = mean.
Compute the mean and standard deviations of the two data set in Excel using the following functions.
Mean=AVERAGE()
Standard deviation=STDEV.S()
Consider the Excel sheet attached.
The mean and standard deviation of weight are:
Mean = 202, Standard deviation = 11.87
And the mean and standard deviation of weight are:
Mean = 25.88, Standard deviation = 2.75
Compute the coefficient of variation for the weight as follows:
Compute the coefficient of variation for the age as follows:
Thus, the coefficient of variation for the weight and age are 5.9% and 10.6%.
