ERROR ANALYSIS Describe and correct the error in solving the equation
* + 10x + 74 = 0
-10 + 102 - 4(1)(74)
2(1)
-10 V-196
-10 : 14
= -12 or 2

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x

The standard deviation for a set of data is 5.5. the mean is 265. what is the margin of error?

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function.a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.
