c)
Step-by-step explanation:
Hi there!
A function, when it comes to discussing the degree of a polynomial one. We classify them accordingly to the highest exponent.
f(x)=-3x+2 (1st degree since -3x=-3x¹)
f(x)=0x² +3x-3 well, 0x²=0 then f(x)=0x² +3x-3=f(x)=3x-3 (1st degree Linear function with b≠ 0)
f(x) =-7x²-x+2 (2nd degree -Quadratic Function)
f(x)=2x³+2x²-4 (3rd degree -Cubic Function)
So it's the third one from top to bottom, or c) f(x)=-7x²-x+2

<u>Answer:</u>
(-1, 5)
<u>Step-by-step explanation:</u>
The center of a circle is the midpoint of the diameter.
So we have to calculate the midpoint of the diameter, using this formula:
midpoint = ( ,
)
= ( ,
)
= (-1, 5)
∴ The center of the circle lies at the point (-1, 5).
Introduce the following notations of events:
A "The person has the disease"
B "The test is positive", C "the test is erroneous"
Our formula will be then:
So the probability we are looking for is 0.19
