Answer:
A. True
B. True
C. True
D. False
Step-by-step explanation:
Option D is the only clear option that is false.
The S distribution is a statistical tool used to check the homogeneity of two independent estimates when studying population variance.
When using an F distribution, The ratio of the degree of freedom of the numerator to the denominator can be >1, = 1 or < 1.
This implies that degrees of freedom for the denominator can be smaller than the degrees of freedom for the numerator.
This makes option D false and hence the correct answer
Answer:
y = - 
x
Step-by-step explanation:
the equation of a linear function in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 8, 2) and (x₂, y₂ ) = (1, - 4) ← 2 ordered pairs from the table
m = 
= 
= 
= -
the ordered pair (0, 0 ) indicates the line crosses through the origin, then
c = 0
y = - x + 0 , that is
y = - x ← equation of linear function
Answer:
the bottom left one (the graph that looks like a circle) is not a function, but the other ones are.
Step-by-step explanation:
A function is defined so that for every x value within a function has a y value. This means that an x value CANNOT have more than one y value. The bottom right one has two y values for almost every x value within the domain. The top ones are functions, because all x values have only 1 y value (a discontinuous function is still a function!) And the bottom right is too.
The first answer is C.
The second answer is A.
