Answer:
16
Step-by-step explanation:
The sample mean for machine #1 is obtained by simply adding up the four sampled units of output for the machine (17, 15, 15, 17) and then dividing the result by four:
![m=\frac{17+15+15+17}{4}\\ m=16](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B17%2B15%2B15%2B17%7D%7B4%7D%5C%5C%20m%3D16)
Therefore, the sample mean for machine #1 is 16.
The functions b,d, and f have complex roots{ as the graph has no intersections with the x-axis}
Function: A function is defined as a relationship between a set of inputs that each have one output. A function is a relationship between inputs in which each input is related to exactly one output. Every function has a domain and a codomain, as well as a range. In general, a function is denoted by f(x), where x is the input. A function's general representation is y = f. (x).
Complex roots: Complex roots are the fictitious roots of equations represented by complex numbers. Because taking the square root of a negative number is impossible, we convert it to a complex number.
In the shown figure the functions b,d and f do not touch the x-axis which means it has complex roots {image attached}
Therefore, The function b,d, and f have complex roots{ as the graph has no intersections with the x-axis}

Answer:
b = 4.6
Step-by-step explanation:
y = 0.3x + b
(4) = 0.3(-2) + b
4 = -0.6 + b
b = 0.6 + 4
b = 4.6
