A TELCO office has seven telephone lines. For the past months, the probability distribution of the random variable X which represents the number of busy lines per day, X={0, 1, 2, 3, 4, 5, 6, 7} P(X)={.02, .27, .06, .22, .15, .04, .08, .16}, what is the probability that the number of busy telephone lines in a day is fewer than six but at least one?
Supposed three cellphones are tested at random. Let D represent the defective cell phone and N let represent the non-defective cell phone. If we let X be the random variable for the number of defective cell phone, construct the probability distribution of the random variable X.
Acetaldehyde has absorption signals at 160, 180 and 290 nm What type of transitions are responsible for each of these absorptions?
A capacitor of capacitance micro-microfarads consists of two parallel plates each moving an area of 200 cm¹, separated in air a distance d apart. This condenser is charged to a difference in potential of 200 V and it is then disconnected from the source. Find (a) the distance of separation d. (b) the charge stored in the condenser. (c) the work done in storing this charge, and (d) the work needed to pull the plates apart to a distance of 3d.
The uniform bar weighs 45 N and is subjected to the forces as shown. Find the magnitude, location and direction of the force needed to keep the bar in equilibrium
