The Precision Scientific Instrument Company manufactures thermometers that are supposed to give readings of O'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 O C (denoted by negative numbers) and some give readings
above o'c (denoted by positive numbers). Assume that the mean reading is o 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.
Find Q3 the third quartile.

found it xd it ok yt

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

it is 28 degrees colder in detroit than philadelphia.

step-by-step explanation:

what number adds to 21

-7 + ? = 21

-7 + 28 = 21
