Answer:20.39
Step-by-step explanation:
This is the answer because 5.30/11.1=0.447 dollars per peso. Thus given 42.7pesos: Dollars = 0.447*42.7=20.39 dollars
Three bottles would cost $2.97.
With tax:
1.05(2.97) = 3.1185 (around 3.12)
The bottles would cost around $3.12 with tax
4 3/4 equals 19/4ths so the correct answer would be 19 burgers
Answer:
There is a 25.14% probability that the order will not be met during a month.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean \mu and standard deviation
, the zscore of a measure X is given by

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. Subtracting 1 by the pvalue, we This p-value is the probability that the value of the measure is greater than X.
In this problem, we have that:
.
The order will not be met if
. So we find the pvalue of Z when
, and subtract 1 by this value.



has a pvalue of 0.7486.
So there is a 1 - 0.7486 = 0.2514 = 25.14% probability that the order will not be met during a month.
