People with a body mass index (BMI) of over 30 are considered obese. Recent reports indicate the rate of obesity is climbing nation-wide. In the 2011 report, Mississippi had the highest obesity rate, at 34.5% of adults. Georgia was in eighteenth place at 30.4%, while Colorado ranked last in obesity at 19.8%. If we selected a random sample of 1,000 adults from these three states and observed the number of obese individuals in the sample, X, the number of obese individuals .

345

304

198

Step-by-step explanation:

What we must do is calculate the number of obese individuals for each state according to the given probabilities, we have that the sample is 1000 people, so:

For Mississippi:

1000 * 34.5% = 345  obese people

For Georgia:

1000 * 30.4% = 304  obese people

For Colorado:

1000 * 19.8% = 198 obese people

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
