One measure of general health is your body mass index (bmi). adults with a bmi between 18.5 and 24.9 are generally considered to have an ideal body weight for their height. the mean bmi for adults in a certain country is 24.6. suppose the bmi for adults in this country is normally distributed with standard deviation 1.2. (round your answers to four decimal places.) suppose one adult from this country is selected at random. what is the probability that the person's bmi is more than 25.5?

0.2266

Step-by-step explanation:

Let x represents the the BMI for adults .

As we consider the given description, we have

We assume that  the BMI for adults in this country is normally distributed with standard deviation 1.2.

Then, z-value for x=25.5 will be:-

P-value :

[using z-value table.]

Hence, the probability that the person's BMI is more than 25.5 = 0.2266

answer: i think it is (1,-2)

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
