P = 10log Io) is used to find the sound level, P, in decibels (dB), of a sound with an intensity of I. In the formula, o represents the Type the correct answer in the box. Use numerals instead of words.
The formula
smallest sound intensity that can be heard by the human ear (approximately 10–12 watts/meter?
What is the sound intensity of a noise that is 130 dB?
The sound intensity is
watts/meter?

There is a line with slope 1/a going through the point (a, a²). find the equation of the line perpendicular to this line at this point. (don’t let this problem intimidate you! solve the problem as you would if i’d given you specific values. just use variables instead.)

The multiplicative property of equality states that for real numbers a, b, c, and d, if a = b and c = d, then ac = bd. true false

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
