answer=$82.92
If the length of OA is 1.80 units. Then the length of segment AB will be 0.80 units.
<h3>What is a Pythagoras theorem?</h3>
The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
Line AC is perpendicular to the circle centered at O with a radius of 1 unit. The length of AC is 1.5 units.
The figure is shown below.
Then the length of segment AB will be
AB = OA - OB
AB = OA - 1
Then the OA will be
OA² = OC² + AC²
OA² = 1² + 1.5²
OA² = 1 + 2.25
OA² = 3.25
OA = 1.80 units
Then we have
AB = 1.80 - 1
AB = 0.80 units

<span>The answer is 0.06325. The probability of detecting the true presence is 98% = 0.98. The probability of not detecting the true presence is: 100%-98% = 2% = 0.02. The probability of detecting the true absence is 97% = 0.97. The probability of not detecting the true absence is: 100%-97% = 3% = 0.03. The probability of having the disorder is: 3.5% = 0.035. The probability of not having the disorder is 100% - 3.5% = 96.5% = 0.965. The probabilty of having a disorder and detecting the true presence is: 0.035 * 0.98 = 0.0343. The probability of not having the disorder and detecting the true absence is: 0.965 * 0.03 = 0.02895. The probability that a randomly chosen person tests positive is: the probabilty of having a disorder and detecting the true presence + the probability of not having the disorder and detecting the true absence = 0.0343 + 0.02895 = 0.06325.</span>
