16x + 9 = 9y − 2x (add 2x to each side)

16x + 2x + 9 = 9y - 2x + 2x

18x + 9 = 9y (divide 9 from each side)

(18x + 9)/9 = 9y/9

18x/9 + 9/9 = y

2x + 1 = y <-answer

Weekly demand for a product is normally distributed with a mean and standard deviation of 3,211 and 484 units, respectively. Wha

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
