The precision scientific instrument company manufactures thermometers that are supposed to give readings of 0°c at the freezing point of water. tests on a large sample of these thermometers reveal that at the freezing point of water, some give readings below 0°c (denoted by negative numbers) and some give readings above 0°c (denoted by positive numbers). assume that the mean reading is 0°c and the standard deviation of the readings is 1.00°c. also assume that the frequency distribution of errors closely resembles the normal distribution. a thermometer is randomly selected and tested. find the temperature reading corresponding to the given information. round your answer to two decimal places.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
