The sat mathematics scores in the state of florida are approximately normally distributed with a mean of 500 and a standard deviation of 100. using the empirical rule, what is the probability that a randomly selected student’s math score is between 300 and 700? express your answer as a decimal.

The answer is 0.95

Step-by-step explanation:

Under the empirical rule, or the three sigma rule or 68-95-99.7 rule, as given in the question 300 and 700 are two standard deviations from the mean 500. So, the probability that a randomly selected students math score is between 300 and 700 is 0.95.

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
