Answer: C)27:1
Step-by-step explanation:
Given, Kent has two similar cylindrical pipes, Pipe A and Pipe B. The radius of Pipe A is 6 cm, and the radius of Pipe B is 2 cm.
Volume of cylinder = , where r= radius and h = height.
Also, If two figures are similar then ratio of volume is equal to the cube of any dimension .
The ratio of the volume of Pipe A to the volume of Pipe B is given by :-
Thus, the ratio of the volume of Pipe A to the volume of Pipe B = 27:1
So, the correct option is C)27:1.

Step-by-step explanation:
The following formula is used to compute the Proportion of error-free units given the sigma level in Excel.
<em> The proportion of error-free units = NORMSDIST(Sigma Level - 1.5) </em>
Suppose that a process is currently operating at a 3.5-sigma quality level.
The proportion of error-free units for this process is
NORMSDIST(3.5 - 1.5) = 0.977250
Therefore, the rejection rate is equal to
or 22750 PPM.
Now, consider a 6-sigma level process.
The proportion of error-free units equals
NORMSDIST(6.0 - 1.5) = 0.9999966
and the rejection rate is
Hence, reduction is PPM required per year , that is
reduction per year
Answer:
$7995.85
Step-by-step explanation:
We will use simple interest formula to solve our given problem.
, where,
A = Amount after t years,
P = Principal amount,
r = Annual interest rate in decimal form,
t = Time in years.
Therefore, Judy will will pay back on January 20: <u>$7995.85</u>.
