Spray drift is a constant concern for pesticide applicators and agricultural producers. the inverse relationship between droplet size and crift potential is well known. a researcher is interested in the effects of herbicide formulation on spray atomization. the researcher believes a normal distribution with mean 1050 μm and standard deviation 150 μm 1s a reasonable model for droplet size for water the "control treatrment") sprayed through a 760 ml/min nozzle
(a) what is the probability that the size of a single droplet is less than 1425 μm? greater than 900 μm? (round your answers to four decimal places.) less than 1425 μm greater than 900 μ m
(b) what is the probability that the size of a single droplet is between 900 and 1425 μm? (round your answer to four decimal places)
(c) how would you characterize the smallest 2% of all droplets? (round your answer to two decimal places.) the smallest 2% of droplets are those smaller than um in size.
(d) if the sizes of five independently selected droplets are measured, what is the probability that at least one exceeds 1425 μm? hint: see binomial distribution for lesson 6, (round your answer to four decimal places.)

the answer to the question is a  

it has the same slope and the same y-intercept.

answer: do we write it

step-by-step explanation:

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
