To express a decimal number (with a finite decimal expression) in a fraction, you work like this: the numerator is the number without decimale separator (you simply pretend it's not there), while the denominator will be , where n is the number of digits after the decimal separator.
So, in your case, the number without decimal separator is 53, and you have two digits after the decimal separator, so the fraction will be
which is irreducible.
Answer:
l = 6 inches
Step-by-step explanation:
We have,
The volume of a rectangular prism with a square base is .
Height of the prism is 5 in
It is required to find the length of the edge of the square base. Let it is l.
The formula of the volume of the rectangular prism is given by :
A is area of base of prism
It has a square base, l =b
So, the length of the edge of the square base is 6 inches.
Answer:
Step-by-step explanation:
The confidence interval for population mean is given by :-
, where is the sample proportion, n is the sample size ,
is the critical z-value.
Given : Significance level :
Sample size : n= 85
Critical value :
Sample proportion:
Now, the 99% confidence level will be :
Hence, the 99% confidence interval estimate of the true proportion of families who own at least one DVD player is
