Multiply (7 +81)(7-81) (7 + 81)(7 - 8) = (Type your answer in the form a+bi)
Solve 4(3x2 –2x+3) = 108
Exhibit 8-3 A random sample of 81 automobiles traveling on a section of an interstate showed an average speed of 60 mph. The distribution of speeds of all cars on this section of highway is normally distributed, with a standard deviation of 13.5 mph. Refer to Exhibit 8-3. If the sample size was 25 (other factors remain unchanged), the interval for μ would _____. Group of answer choices become wider become zero become narrower not change
