Answer:
(x−5y)(9x+8)
Step-by-step explanation:
9x^2−45yx+8x−40y
Do the grouping 9x^2−45yx+8x−40y=(9x^2−45yx)+(8x−40y), and factor out 9x in the first and 8 in the second group.
9x(x−5y)+8(x−5y)
Factor out common term x−5y by using distributive property.
(x−5y)(9x+8)

Answer:
The answer is "".
Step-by-step explanation:
Please find the complete question in the attached file.
We select a sample size n from the confidence interval with the mean and default , then the mean take seriously given as the straight line with a z score given by the confidence interval
Using formula:
The probability that perhaps the mean shells length of the sample is over 4.03 pounds is
Now, we utilize z to get the likelihood, and we use the Excel function for a more exact distribution
the required probability:
