Answer:
20, 11
Step-by-step explanation:
x=first Number
x-9=second number
above two added together=31 or
x+(x-9)=31
2x=40
x=20 first number
x-9=second number
20-9=11 second number
20 (first number) + 11 (second number)=31
31=31
Answer:-9
Step-by-step explanation:
Answer:
x=0
Step-by-step explanation:
9^x=1
Anything raised to the zero power is 1 (except 0 but that is another math class)
9^0 =1

Answer: A bag can weigh 13.77 ounces and not need to be repacked.
Step-by-step explanation:
Since we have given that
Mean = 12.08 ounces
Standard deviation = 1.03 ounces
Bags in the upper 5% are too heavy and must be repackaged.
Using the standard normal table.
z = 1.645
So, ![X=\mu+z\sigma\\\\X=12.08+1.645\times 1.03\\\\X=13.77\ ounces](https://tex.z-dn.net/?f=X%3D%5Cmu%2Bz%5Csigma%5C%5C%5C%5CX%3D12.08%2B1.645%5Ctimes%201.03%5C%5C%5C%5CX%3D13.77%5C%20ounces)
Hence, A bag can weigh 13.77 ounces and not need to be repacked.
