From the graph we can tell that the numbers of liters are 7.5, 7.5, 8.6, and 9.3
add them up, the total is 32.9
Answer:
79.25
Step-by-step explanation:
8*5=40
40-3/8=39.625
39.625*2=79.25
Hope this helps
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.
A^2+b^2=c^2 (Pythagoran theorem)
-> 30^2 + length^2 = 78^2
-> length = √6084-900 = <span>√5184 = 72 ft
=> area = length x width = 72 x 30 = 2160 ft^2</span>
The sum of the given expression expressed as a quadratic equation is 10x^2 + 13x + 11
<h3>Sum of expressions</h3>
Expressions are equations separated by mathematical signs. This expressions are known to contains certain unknowns
Given the following expression
10x^2 +7x+6 and 6x + 5
We are to take the sum of both expression to have:
f(x) = 10x^2 +7x+6 + 6x + 5
Collect the like terms
f(x) = 10x^2 + 7x + 6x + 6 + 5
f(x) = 10x^2 + 13x + 11
Hence the sum of the given expression expressed as a quadratic equation is 10x^2 + 13x + 11
