A ton is 2000 pounds, so multiply that by 8.
Answer:
11 5/8
Step-by-step explanation: add everything to get 11 5:8
When given a value of the variable, we replace each instance of the variable in the problem with that number. In this case, the expression becomes:
After this, we merely need to simplify the answer.
Simplifying 12/2 gives us the answer 6.
For a normal distribution <em>only, </em>for a population, not for particular sample.
proportion between 1 standard deviation, independent of μ and σ , is given by:
P(Z<1)-P(Z<-1)
=0.841345-0.158655=0.682689
=0.68 (to two places of decimal)
proportion between 2 standard deviations, independent of μ and σ , is given by:
P(Z<2)-P(Z<-2)
=0.977250-0.022750=0.954500=0.95 (to two places of decimal)
