determine whether the relations represented by the matrices in exercise 4 are reflexive, irreflexive,
symmetric, antisymmetric, and/or transitive.
s={(1,1), (1,2), (1,4), (1,5), (1,6), (2,1), (2,3), (3,1), (3,2), (3,3), (3,4), (4,1), (4,3), (4,4)}
s={(1,1), (1,2), (1,3), (2,1), (2,2), (3,3), (3,4), (4,1), (4,4)}
s={ (1,2), (1,4), (2,1), (2,3), (3,2), (3,4), (4,1), (4,3)}

the correct answers i think are b. and d.

give me brainliest if it is correct!

step-by-step explanation:

graph using a few selected

x         y

-1       15

0         6

1         2.4

2       0.96

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33

choose (5, 1.5) and (-1.5,-3.5)

step-by-step explanation:

5 - 1.5 =3.5

-1.5 - (-3.5) = 2

3.5 + 2 =5.5

hope this !
