80 volunteers take a meningitis test to help doctors see how accurate this test is at identifying whether someone has meningitis or not. A positive result means the test has identified you as having meningitis. Of the volunteers, only 17 people have meningitis. The results show 5 people who have meningitis gets a negative result and 7 people who don't have meningitis get a positive result. What was the accuracy of the test?

if i put something wrong your not gonna like it so rather not say nothing.

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!

the answer is a) y= 2 csc [0.5 (x+pi/2)]-1
