Answer:
- When we are having a rational expression i.e. a expression of the type:
Where f(x) and g(x) are polynomial functions.
Now the domain of this rational expression is whole of the real numbers except the points where the function g(x) will be zero.
Hence we have to exclude the points where the given denominator quantity is zero.
- Let us consider an example as:
Let R(x) denote the rational function as:
Now the domain of this rational function will be whole of the real line minus the points where the denominator is zero.
We know that (x-2)(x-3) is zero when x=2 or x=3.
Hence, the domain of R(x) is: R- {2,3}.
Answer:
The minimum sample size required to create the specified confidence interval is 1024.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
What is the minimum sample size required to create the specified confidence interval
This is n when 
.
The minimum sample size required to create the specified confidence interval is 1024.
Answer:
A= pi r(r+h2+r2)
Step-by-step explanation:
Multiply the radius by pi, then set that aside for a bit.
Square the height and the radius as well, then add those together. This is how it would look:
3.14 x 4 = 12.56
7 x 7 = 49 ; 4 x 4 = 16 ; 16 + 49 + 4 = 69 ; 69 x 12.56
I think this is the answer. Can't say I'm 100% sure, though.
Answer:
$0.21/lb
Step-by-step explanation:
We are to find the price per pound:
Number of tons given = 2 tons;
1US ton contains 2000lb
2 tons will have mass of 2 x 2000 = 4000lb
price = $840
So';
Price per pound = 
= $0.21/lb
