The yield in bushels per acre is related to the average temperature. The attached sample data was obtained in a recent study. The least-square regression equation for yield in bushes and the average temperature is:Region Temperature Yield (in bushels per acre)1 4 32 8 73 10 84 12 105 9 86 6 4A) y = 1.3 + 1.1x B) y = 2.1 + 0.9xC) y = -0.8 + 0.9x D) y = -1.3 + 1.1x E) None of these

Idon’t understand this.. will someone ? will mark brainliest along with 20 points.

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.

Maria found the least common multiple of 6 and 15. her work is shown below. multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, . . multiples of 15: 15, 30, 45, 60, . . the least common multiple is 60. what is maria's error?
