Your question was a little vague so i solves for x and y using elimination.
8.75 because 656 goes up to 700 since the tens out place is 50
Answer:
The answer is below
Step-by-step explanation:
The domain of a function is the set of all independent variables for the function while the range of a function is the set of all possible dependent variables.
Let x represent the number of newspaper lines and f(x) be the charges for advertisement. x is the independent variable and f(x) is the dependent variable.
Since the newspaper charges $3 per line for the first 4 lines plus a $20 fee to advertise, the function is given as:
f(x) = 3x + 20 for 0 < x < 4
But for more than four lines, the charges is given as:
f(x) = 12 + 20 = 32 4 < x < ∞
Therefore, the domain and range of the function is:
Domain = (0, ∞)
Range = (20, 32}
Answer:
The sigma capability of the process is 5.2857
Step-by-step explanation:
The sigma capability of a process is defined by the number of times that the distance between the lower specification limit and the upper specification limit contains the value of the standard deviation. In this case:
(USL - LSL) / sd = (247 - 265.5) / 3.5 = 5.2857
Then, the sigma capability of the process is 5.2857
