Answer:
A. The mean is 0.51 and the standard deviation is 0.0142.
Step-by-step explanation:
When we know the mean of the population (0.51), we don't need to estimate the mean of the sampling distribution from the mean of a sample (0.63).
Then, the mean of the sampling distribution is equal to the mean of the population (0.51).
The standard deviation is calculated as:
200 adult tickets were sold, and 100 student tickets were sold
To calculate the length of the diagonal, use the Pythagorean theorem:
c^2 = a^2 + b^2, where c is the diagonal.
c^2 = 65^2 + 34^2
c^2 = 4225 + 1156
c^2 = 5381
c ~ 73.36
To the nearest tenth of a meter, the diagonal has a length of 73.4 m
Answer:
$1200
Step-by-step explanation:
According to the question,
$500 for airline ticket plus $100 each day .
