The lifespans of loins in a particular zoo are normally distributed. The average lion lives 12.5 years; the standard deviation is 2.4 years.

Use the empirical rule (68 - 95 - 99.7%) to estimate the probability of a lion living less than 10.1 years.

1/3 + 1/5 = 8/15.

answer: $1794

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
