Acompany that manufactures large lcd screens knows that not all pixels on their screen light, even if they spend great care when making them. they know that the manufacturing process has a blank pixel rate, on average, of 4.4 blank pixels in a sheet 4 ft by 8 ft that will be cut into smaller screens. they believe that the occurrences of blank pixels are independent. their warranty policy states that they will replace any screen sold that shows more than 2 blank pixels. suppose the number of blank pixels can be modeled by a poisson distribution. complete parts a) through d) below. a) what is the mean number of blank pixels per square foot? the mean is pixel(s). b) what is the standard deviation of blank pixels per square foot? the standard deviation is pixel(s). c) what is the probability that a 2 ft by 3 ft screen will have at least one defect? a 2 ft by 3 ft screen will have at least one defect with probability. d) what is the probability that a 2 ft by 3ft screen will be replaced because it has too many defects? a 2 ft by 3 ft screen will need to be replaced with probability .

Ican interpret and represent the remainder in division calculations sensibly for the context (eg if we wont to know how many 40 seat buses will be needed to transport 170 students for on excursion, we divide 170 by 40 and realise buses and another smaller vehicle to that we need 4 transport 10 more students) solve the following questions. show your work! 11) the zoo had 420 butterflies that needed to be transported to a new enclosure. the boxes that the butterflies would be moved in only hold 80 butterflies in each. how many boxes would they need? 2 12) each classroom in the school can have exactly 25 students, if there are 345 students in the school how many full classrooms are there?

Mr. jones determined that the equation y = 98 - 16/5 x could be used to predict his students' unit test scores, based on the number of days, x, a student was absent during the unit. what was the meaning of the y-intercept of the function? (by the way the 16/5 is a )
