%change=100(final-initial)/initial,
%change=100(New price-Original price)/Original price
(Original price*%change)/100=New price-Original price
New Price=(Original price*%change+100*Original price)/100
New Price=Original price(100+%change)/100
Since %change is -4%...
New Price=0.96(Original price)
...
Since original price is $45400
New Price=0.96(45400)
New Price=$43584
The answer would be 390+ 390 =780
Answer:

will give you an explanation if you want tag me on comment.
The formula for finding the area of a triangle is: base*height*1/2
So, if we use this information....
4.2*5.5*1/2=11.55
Area=11.55
Answer:
0.000064 = 0.0064% probability that the box will contain less than the advertised weight of 466 g.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean
and standard deviation
, the z-score of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
N(489,6)
This means that 
What is the probability that the box will contain less than the advertised weight of 466 g?
This is the p-value of Z when X = 466. So



has a p-value of 0.000064
0.000064 = 0.0064% probability that the box will contain less than the advertised weight of 466 g.
