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.
Answer:
cubic function
Step-by-step explanation:
y = x³ is a cubic function ( cube relating to the exponent 3 )
It can also be called a degree 3 function
Answer:
y(.82)*1.08
Step-by-step explanation:
You multiply by .82 to get the cost of the game after the discount and then by 1.08 to add the tax and total amount.
Answer:
Using the charasteristics of a parallelogram, the length of line segment MX is 8 in (Third option).
Step-by-step explanation:
In parallelogram WXYZ:
WY=12 in., this is a diagonal in the parallelogram
XZ=16 in., this is the other diagonal in the parallelogram
WX=10 in., this is one of the sides of the parallelogram
XY=9 in., this is the other side of the parallelogram
MX=? this segment is between the vertex X and the point of intersection of the diagonals
In a parallelogram the diagonals intersect (point M) dividing them in equal parts each other, then:
MX=MZ=XZ/2
MX=MZ=(16 in.)/2
MX=MZ=8 in.
Answer:
Step-by-step explanation:
The density of an object can be found by taking its mass and dividing by its volume.
Hence if density is D , Mass is M and Volume is V
a)
M = 500 gms
V = 40 cubic cm
b)
M = 125 gms
V = 1.4 cubic cm
D =89.28 gm per cc
