Answer:
The correct option is;
y - P = two fifths (x - Q).
Step-by-step explanation:
The equation for the old route is given as follows;
Therefore, we have;
The slope of the equation of the old route = 2/5
Given that the new route is parallel to the old route and passes through the point (Q, P), the slope of the new route = 2/5 and the equation of the new route in slope and intercept form can be written as follows;
y - P = 2/5×(x - Q)
Therefore, the correct option is y - P = two fifths (x - Q).
Answer:
The mean of the sampling distribution of the proportion of downloaded books is 0.03 and the standard deviation is 0.0197.
Step-by-step explanation:
Central Limit Theorem
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean and standard deviation
3% of books borrowed from a library in a year are downloaded.
This means that
SRS of 75 books.
This means that
What are the mean and standard deviation of the sampling distribution of the proportion of downloaded books
By the Central Limit Theorem
Mean:
Standard deviation:
The mean of the sampling distribution of the proportion of downloaded books is 0.03 and the standard deviation is 0.0197.
