Suppose that diastolic blood pressure readings of adult males have a bell - shaped distribution with a mean of 79 mmHg and a standard deviation of 10 mmHg . Using the empirical rule what percentage of adult males have diastolic blood pressure readings that are less than 89 mmHg ? Please do not round your answer .

wht? how is this math

Step-by-step explanation:

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

so, converting firstly the mixed fractions to improper fractions and then "adding".
