Answer:
Normal Distribution
Standard error = 0.473
Step-by-step explanation:
We are given the following information:
A procurement specialist has purchased 25 resistors from vendor 1 are assumed to be normally distributed with mean 100 ohms and standard deviation 1.5 ohms.
A procurement specialist has purchased 30 resistors from vendor 2 are assumed to be normally distributed with mean 105 ohms and standard deviation 2.0 ohms.
The difference of two independent normally distributed random variables is normal, with its mean being equal to the difference of the two means, and its variance being the sum of the two variances.
Thus, the sampling distribution of is a normal distribution.
Mean =
Standard error =
Answer:
f(x)-values
decreased by 4
(4,87)
Step-by-step explanation:
The table shows the exponential growth function
substitute some values to find
Subtract these equations:
Divide them:
Then
Hence,
Therefore, the parent function is
If this function would be translated 4 units down, its expression will be
This means that f(x)-values decreased by 4.
Then the table for translated function is
The graph of translated function passes through the point (4,87)
