Answer:
38.93857982... is a irrational because it is a non-terminating, non-repeating decimal.
Step-by-step explanation:
Irrational number: the number which cannot be represented in the form of p/q where p and q are integer and q not equal to 0. In other words a Irrational number is a non terminating non repeating decimal number.
If you would like to solve the system of equations, you can do this using the following steps:
3x + y = 3
x + y = 2 ... y = 2 - x
_________________
<span>3x + y = 3
</span>3x + 2 - x = 3
2x = 3 - 2
2x = 1
x = 1/2
y<span> = 2 - x = 2 - 1/2 = 1 1/2 = 3/2
(x, y) = (1/2, 1 1/2) = (1/2, 3/2)
The correct result would be </span><span>C) x = 1/2, y = 3/2.</span>

c = -4/9; c = 2
Step-by-step explanation:
Answer:
P(POSc/Sc)
Step-by-step explanation:
As,
POS= Test has positive results
and
S=Adult has tuberculosis.
The test correctly identifies 74.6% of the time adults with a tuberculosis and correctly identifies those without tuberculosis 76.53% of the time.
In the above statement 76.53% describes the probability of adult who don't have tuberculosis gets the negative results as test is correctly identifying.
So, getting negative results means that not positive results and for this event the notation of complement POSc is used. Also, not having tuberculosis can be denoted as Sc. So,
POSc= Test has negative results
Sc=Adult hasn't tuberculosis
Thus, P(POSc/Sc) depicts the probability of adults not having tuberculosis gets correct results.
Hence, P(POSc/Sc)=76.53%

Answer:</h2>
The graph on the top left.
<h2>
Step-by-step explanation:</h2>
f(x) = 
That means that when x = 0...
f(0) = 
f(0) = -1 - 3
f(0) = -4
So, the function will have a point at (0, -4). We can eliminate the two graphs on the right.
When x = 1...
f(1) = 
f(1) = -4 - 3
f(1) = -7
So, the function will have a point at (1, -7). That corresponds to the graph on the top left.
