Answer:
The standard error of the proportion is 0.0367.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean 
and standard deviation 
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation 
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the standard error is 
In this question:
So
The standard error of the proportion is 0.0367.
Answer:
Now if the high and low monthly average temperatures satisfy the inequality, then the , monthly averages are always within 22 degrees of 43°F.
Step-by-step explanation:
The inequality describes the range of monthly average temperatures T in degrees Fahrenheit at a certain location.
The inequality expression is given as:
now this expression could also be expressed as:
Now if the high and low monthly average temperatures satisfy the inequality, then the , monthly averages are always within 22 degrees of 43°F.
( As the difference is 22 degrees to the left and right)
Answer: Total amount the stadium would clear for all of these events combined is $1750000
Step-by-step explanation:
Since we have given that
Number of major recording acts are able to play at the stadium = 10
Average profit margin for a concert = $175000
We need to find the amount that the stadium clear for all of these events combined
As we know the formula for "Average"
Hence, total amount the stadium would clear for all of these events combined is $1750000.
The transformation was a 180° rotation about the origin.
Because, if we take formulas of rotation about the origin:
X1=x*cos£+y*sin£.
Y1=-x*sin£+y*cis£.
And £=180°
Than we recieve
x1=-x
y1=-y
2.47*10^8=247000000
take 2.47 and move the decimal point 8 times to the right. Fill empty spaces with zeros
