The bnt drilling company is planning to drill an oil well at a certain location in bacoor, cavite. according to analysis, there is 30% chance of hitting oil, a 20% chance of hitting gas, a 10% chance of hitting a combination well and a 40% chance of hitting an empty well. it is estimated that the net return would be p950,000 for an oil well, p600,000 for a gas well, p1,500,000 for a combination well, and a loss of p300,000 for an empty well. find the expected value?

Find the value of x. round the length to the nearest tenth

In a test for esp (extrasensory perception), the experimenter looks at cards that are hidden from the subject. each card contains either a star, a circle, a wave, a cross or a square.(five shapes) as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. when the esp study described above discovers a subject whose performance appears to be better than guessing, the study continues at greater length. the experimenter looks at many cards bearing one of five shapes (star, square, circle, wave, and cross) in an order determined by random numbers. the subject cannot see the experimenter as he looks at each card in turn, in order to avoid any possible nonverbal clues. the answers of a subject who does not have esp should be independent observations, each with probability 1/5 of success. we record 1000 attempts. which of the following assumptions must be met in order to solve this problem? it's reasonable to assume normality 0.8(1000), 0.2(1000)%30 approximately normal 0.8(1000), 0.2(1000)% 10 approximately normal srs it is reasonable to assume the total number of cards is over 10,000 it is reasonable to assume the total number of cards is over 1000
