Answer:
g(x) = -∛(x-7)
Step-by-step explanation:
Reflection in the y-axis changes the sign of x, so after this transformation, the function is ...
g(x) = f(-x)
Then, translation 7 units to the right replaces x by (x-7), so after both transformations, the function is ...
g(x) = f(-(x -7)) = f(-(x -7))
Using the given definition for f(x), we have ...
Answer:
Option 2: 1.5 is the correct answer.
Step-by-step explanation:
Given information is:
Mean = μ = $27
SD = σ = $5.50
A z-score simply tells us how far a selected data value from the mean is.
Z-score is denoted by z and is given by the formula:
Let x = $35.25
Putting the values of mean and SD we get,
The value of z-score for a price of $35.25 per barrel is 1.5
Hence,
Option 2: 1.5 is the correct answer.
