Algebra.Com's Answer #136764 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! The average cost of a certain type of seed per acre is $42. The standard deviation is $3. Using Chebyshev's theorem, find the range in which at least 88.89% of the the values will fall. \n" ); document.write( "Please help me with this problem I understand that 1-1/k2 but i don't know who to apply it... please help me. \n" ); document.write( "------------------------------------ \n" ); document.write( "Equation: \n" ); document.write( "1 - (1/k^2) = 0.8889 \n" ); document.write( "1/k^2 = 0.1111111 \n" ); document.write( "k^2 = 9 \n" ); document.write( "k = 3 \n" ); document.write( "---------------- \n" ); document.write( "You want the range of values within 3 standard deviations of the mean. \n" ); document.write( "42-3*(standard dev.) <= cost <= 42+3(standard deviation) \n" ); document.write( "42-9 <= cost <= 42+9 \n" ); document.write( "$33 <= cost <= $51 \n" ); document.write( "============================ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "==================== \n" ); document.write( " \n" ); document.write( " |
