Answer:
C. Domain: {}, Range: all real numbers;No, it is not a function
Step-by-step explanation:
From the diagram in the attachment, the domain is {}.
The reason is that, the furthest the graph could extend is 8 to the right and left of the y-axis.
The range of the relation is all real numbers. The reason is that, the graph extends up above and below the x-axis without bounds.
The relation is not a function, because its graph failed the vertical line test.
See graph
The correct answer is C.
Answer:
Step-by-step explanation:
a). Mean of the given data set =
= 28
b). x
32 32-28 = 4 16
28 28 - 28 = 0 0
18 18 - 28 = -10 100
40 40 - 28 = 12 144
22 22 - 28 = -6 36
= 296
c). Standard deviation =
=
= 7.69
d). Mean of the new set of weights =
= 34
Since mean of the data set is more close to each data, standard deviation will be less than the deviation given in part (c).
