Answer:
The percentage of legal quarters that will be rejected is 1.954 %.
Explanation:
Here we are required to find
P(X<5.48 or X>5.82)
We have μ = 5.67 and σ = 0.07 where the range is between 5.48 and 5.82 we each z-score given by
Therefore for 5.48 we have = -2.714
and for 5.82 we have = 2.143
Therefore we have the area of interest on the normal distribution chart given by
P(Z<-2.714) + P(Z > 2.143) = P(Z<-2.714) + (1 - P(Z < 2.143))
+ 0.00336 + 1 - 0.98382 = 0.01954
= 0.01954 × 100 = 1.954 %
Therefore 1.954 percentage of legal quarters will be rejected.
Answer:
moving the boxes and the furniture up to the fifth floor.
Explanation:
The work done when moving an object up or down is equal to its change of gravitational potential energy:
where
m is the mass of the object
g is the gravitational acceleration
is the change in height of the object
We have two opposite situations:
1) when an object is moved upward, is positive, so the work done W is positive as well: this means that we need to do work in order to move the object, because we have to "win" the effect of gravity, which pulls the object downward
2) when an object is moved downward, is negative, so the work done W is negative as well: this means that we do not need to do work on the object, because it is already done by gravity, which pulls the object downward.
Therefore, more work is done when we are moving the boxes and the furniture up to the fifth floor.
