Hello!
In a function, each input must have only one output. Outputs can have multiple inputs, but each input must have one output. For example, {(4,-1), (4,-2)<span>} is not a function, as 4 has two outputs.
In B, -2 has two outputs, 3 and 1, so it is not the answer.
In C, 3 has two outputs, 5 and 2, so it is not a function.
In D,-1 has two outputs, 1 and 5, so it will not work.
In A, each number has one output, so it is a function.
I hope this helps!</span>

Answer:
The margin of error is 
Step-by-step explanation:
From the question we are told that
The number of student is 
The highest amount is 
$200
The lowest amount is 
$75
The sample mean is 
&140
The Standard deviation of this set is mathematically evaluated as
Substituting values
The margin of error (ME) is mathematically evaluated as
Where 
is the critical value for 
i.e the significance level
From the critical value table this is 
So
Answer:
yes
Step-by-step explanation:
8² + 15² = 17²
64 + 225 = 289
289 = 289
Answer:
the closest part the mechanic can chose is 0.5 inch
Step-by-step explanation:
fractional sizes given to the nearest 64th of an inch = 1/64 = 0.0156
the closest size to 0.492in = 0.492 + 0.0156 = 0.5076 inches
approximately, the closest part the mechanic can chose is 0.5 inch
