(3) Median
Step-by-step explanation:
I would say median because it most likely wouldn't be any of the others. Mean would be thrown off with the outlier 0.80. Mode wouldn't really work for this. I don't think standard deviation would work because this isn't coninuous data.

1.0 is what percent of 3.5
Answers
Answer:
28.57%
Step-by-step explanation:
Let the required percent be x
1.0 is what percent of 3.5 is written as;
1.0 = x% of 3.5
1.0 = 0.01x * 3.5
0.01x = 1/3.5
0.01x = 0.2857
x = 0.2857/0.01
x = 28.57%
Hence 1.0 is 28.57% of 3.5

The rectangular base of a 3-D printer East 4.5' by 3' in the Keogh's drawing the base of the printer is 3" by 2" of nicaea in larger drawing to 3 times its size would foot the scale of her events draw
Answers
Answer:
[tex]Scale = 1.5[/tex]
Step-by-step explanation:
Given
[tex]Printer = (4.5',3')[/tex]
[tex]Keogh = (3',2')[/tex]
Required
Determine the scale
This is calculated as:
[tex]Scale = \frac{Original}{Actual}[/tex]
[tex]Scale = \frac{(4.5,3)}{(3,2)}[/tex]
Factorize the numerator
[tex]Scale = \frac{1.5 * (3,2)}{(3,2)}[/tex]
Scale = \frac{1.5 * (3,2)}{(3,2)}[tex]Scale = 1.5 * \frac{(3,2)}{(3,2)}[/tex]
[tex]Scale = 1.5 * 1[/tex]
[tex]Scale = 1.5[/tex]

The time between arrivals of customers at an automatic teller machine is an exponential random variable with a mean of 4 minutes. Round yours answers to 4 decimal places. (a) What is the probability that more than three customers arrive in 10 minutes
Answers
Answer:
0.7788 = 77.88% probability that more than three customers arrive in 10 minutes
Step-by-step explanation:
Exponential distribution:
The exponential probability distribution, with mean m, is described by the following equation:
[tex]f(x) = \mu e^{-\mu x}[/tex]
In which [tex]\mu = \frac{1}{m}[/tex] is the decay parameter.
The probability that x is lower or equal to a is given by:
[tex]P(X \leq x) = \int\limits^a_0 {f(x)} \, dx[/tex]
Which has the following solution:
[tex]P(X \leq x) = 1 - e^{-\mu x}[/tex]
The probability of finding a value higher than x is:
[tex]P(X > x) = 1 - P(X \leq x) = 1 - (1 - e^{-\mu x}) = e^{-\mu x}[/tex]
In this question, we have that:
The time between arrivals of customers at an automatic teller machine is an exponential random variable with a mean of 4 minutes, and we have three customers, which means that [tex]m = 3*4 = 12, \mu = \frac{1}{12} = 0.0833[/tex]
(a) What is the probability that more than three customers arrive in 10 minutes
This is P(X > 3). So
[tex]P(X > 3) = e^{-0.0833*3} = 0.7788[/tex]
0.7788 = 77.88% probability that more than three customers arrive in 10 minutes
