Answer:
the graph shift down 135 units
Step-by-step explanation:
when there is no fixing cost:
f(x)=12x-1400
when there is fixing cost (0ne time): 12x-(1400+135)
the graph shift down 135 units

Answer: The correct option is C.
Explanation:
A function is called an odd function if,
It means if the points are in the form of (x,y) then (-x,-y) is also in the graph.
Reason for correct option:
In option C, a point (1,2),
It means,
And we have another point (-1,-2).
The other points are (2,3),(-2,-3),(3,-1),(-3,1),(4,0),(-4,0). Therefore the function is an odd function.
Reason for incorrect option:
In option A, a point is (1,3), therefore the value of function at x = -1 should be -3.
But the value of function is 1 at x=-1, therefore it is not an odd function.
In option B, a point is (1,0), therefore the value of function at x = -1 should be 0.
But the value of function is -3 at x=-1, therefore it is not an odd function.
In option D, a point is (1,-1), therefore the value of function at x = -1 should be 1.
But the value of function is -1 at x=-1, therefore it is not an odd function.
Answer:
(b) Expected number of male kitten E(x) = 1
(c) Standard deviation is ±.
Step-by-step explanation:
Given that,
Number of kittens in a group are 10. Out of these 5 are female.
To find:- (a) create a probability model of male kitten chosen.
So, total number of kitten = 10
number of female kitten = 5
then, Number of male kitten =
Now total number of ways to choosing two kittens from group of 10 =
=
=
for choosing (i) No male P(x=0) = P(Two female) =
=
(ii) 1 male P(x=1) = P(1 male and 1 female) = =
=
(iii) 2 male P(x=2)= P(2 male) = =
0 1 2
P(X=)
(b) what is expected number of male kittens chosen ?
Expected number of male kitten E(x) =
=
(c) what is standard deviation ?
No,
=
= ±
