h(x) = 
-18
Step-by-step explanation:
-b/2a is the formula to find the vertex's x coordinate.
-10/2(1) = -5 and "(x+5)" represents a translation to the left 5 units, so that must be the answer
Answer:
The probability it is greater than or equal to 0.95 and less than or equal to 0.96
Step-by-step explanation:
In order to calculate the probability that weekly demand exceeds 4,044 we would have to calculate the z value as follows:
Z= (X-mean)/standard deviation
Z= (4044 - 3211)/484
Z=1.721
So, looking for standard normal distribution table 1.7 from row, we get values from 0.9554 till 0.9633, for column 0.02 it is 0.9573
Therefore, the probability it is greater than or equal to 0.95 and less than or equal to 0.96
Multiply nominator and denominator by 25:
