8. The mean of the winning scores of a bowling tournament over the last 10 years was 279, with a standard deviation of 3. Considering that the scores were in a normal
distribution, how many scores were below 282?

We

84.134% of the scores

Step-by-step explanation:

-This questions needs as to determine the probability of scores less than 282 then find the expectation;

-Let X be the score of a random selection:

The probability of scores below 282 is 0.84134 or 84.134%

Hence, 84.134% of the scores were below 282

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
