If f(x) is an even function, where f{x) 0, then which one of the following is correct ?
f'(x) is an even function
f'(x) is an odd function
f'(x) may be an even or odd function depending on the type of function
f'(x) is a constant function
Consider the following statements :
1 only
2 only
Both 1 and 2
Neither 1 nor 2
D.
Neither 1 nor 2
The two regression lines are perpendicular to eachother. Actually, they are parallel to the axes, regression line of y on x is parallel to the x-axis and of x on y is parallel to y-axis.
So the regression line coincide
Option D is correct.
If 4x - 5y + 33 = 0 and 20x - 9y = 107 are two lines of regression, then what are the values of respectively
12 and 18
18 and 12
13 and 17
17 and 13
The sum of the binary numbers (11011)2, (10110110), and (10011x0y)2, is the binary number (101101101)2. What are the values of x and y ?
x = 1, y = 1
x = 1, y = 0
x = 0, y = 1
x = 0, y = 0

- 10.0
- 0.5
- 0.4
- 0.2
For the function f(x) = , which one of the following is not correct ?
