Scores on a university exam are normally distributed with a mean of 78 and a standard deviation of 8. the professor teaching the class declares that a score of 70 or higher is required for a grade of at least “c.” using the 68-95-99.7 rule, what percentage of students failed to earn a grade of at least “c”?

Consider the equation 0.2(x – 4.5) + 1.7 = 9.6. 1. use the distribution property. 2. combine like terms. 3. use the properties of equality and inverse operations to isolate the variable. 0.2x + (-0.9) + 1.7 = 9.6 0.2x + 0.8 = 9.6
