Consider writing onto a computer disk and then sending it through a certifier that counts the number of missing pulses. Suppose this number X has a Poisson distribution with parameter μ = 0.3. (Round your answers to three decimal places.) (a) What is the probability that a disk has exactly one missing pulse? .222 Correct: Your answer is correct. (b) What is the probability that a disk has at least two missing pulses? .037 Correct: Your answer is correct. (c) If two disks are independently selected, what is the probability that neither contains a missing pulse? .122 Incorrect: Your answer is incorrect.

Complete the indirect proof to show that two supplementary angles cannot both be obtuse angles. given: angle1 and angle2 are supplementary. prove: angle1 and angle2 cannot both be obtuse. assume that two supplementary angles can both be obtuse angles. so, assume that angle1 and angle2 are obtuse. then mangle1 > 90° (equation 1) and mangle2 > ° (equation 2) by the definition of angles. adding the two inequalities, mangle1 + mangle2 > ° (equation 3). however, by the definition of supplementary angles, mangle1 + mangle2 = (equation 4). so equation 3 contradicts the given information. this means the assumption is , and therefore angle1 and angle2 both be obtuse.

If a cone has the same radius and height as a cylinder, the volume of the cone is one-fourth one-third half two-thirds the volume of the cylinder. If a cylinder and a sphere have the same radius and the cylinder’s height is twice its radius, then the volume of the sphere is one-fourth one-third half two-thirds the volume of the cylinder.
