14. suppose that 1 out of every 10,000 doctors in a certain region is infected with the sars virus; in the same region, 20 out of every 100 people in a particular at-risk population also are infected with the virus. a test for the virus gives a positive result in 99% of those who are infected and in 1% of those who are not infected. a randomly selected doctor and a randomly selected person in the at-risk population in this region both test positive for the disease. who is more likely to actually have the disease?

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.

step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
