Anational survey of asthma conducted on may 1, 2012, obtained the following results for the state of oklahoma:

x = the number of residents with asthma
y = the population of the state on june 30, 2012, and all members of the population were considered at risk
z = the number of new cases of asthma diagnosed during 2012.

the incidence rate of asthma during 2012 (per 100,000) would be expressed as:

The incidence rate per 100,000 =

Step-by-step explanation:

Data provided:

The number of residents with asthma = X

The population of the state on June 30, 2012 = Y

The number of new cases of asthma diagnosed during 2012 = Z

Now,

The incidence rate is the rate or then frequency at which a disease occurs over a time period

Therefore,

In the given question

The incidence rate per 100,000 =

or

The incidence rate per 100,000 =

y > 1/3x

y < = -x + 4

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.
