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.
Mean of 400 and a standard deviation of 60.
This means that 
z=3
We have to find X when Z = 3. So
The data item is
5 * 2 = 10
3^10/3^-2, same base, add
10 - 2 = 8
Solution: 10^8
Answer:
A;C;E
Step-by-step explanation:
Let cost of almond per pound be X
Cost of 3 pounds of almonds=3X
cost of pistachios per pound = X+4
Cost of 2 pounds of pistachios=2X+8
Total cost=5X+8=48
5X+8=48
5X=40
X=8
cost of one pound almond is $8
cost of one pound pistachios is $12

Answer:
Company C
Step-by-step explanation:
You divide the amount of money it all costs to the number of plushies they are selling it for.
A: 34.08/12 = $2.84 each
B: 42.90/15 = $2.86 each
C: 50.58/18 = $2.81 each
So C has the least amount of money spent for a greater amount of plushies so C would be the Best Buy.
It would be: 31/2 / 3/4
we can write it as 31/2 * 4/3 = 62/3
So, your answer is 62/3
