This is a fifth grade math question. You could simply put it in the site calc for an answer.
The curious question is how did you persuade a math person, such as you describe your husband, to marry you? I ask because it most men will not marry someone whose intelligence quotient is more than a standard deviation below their own. Certain physical attributes and social arrangements may compel a marriage but the relationship usually doesn’t last, or is miserable.
It is also extremely rare to find a man married to a woman whose IQ is more than a standard deviation above their own. The men are intimidated by this and women are very put off by comparatively stupid husbands.
If you care to answer, this will help with my sociological studies and may be a basis for a thesis.
BTW the answer to your question is 14.83.
OK I see CPhill already answered your question.
What so you think CPhill? Any thoughts?
