Answer:
156 different pairs will be there.
Step-by-step explanation:
As the order is essential as we need different pairs therefore permutations will be used.
A permutation is any ordered subset of the objects r selected with regard to their order, from the set of n distinct objects. It is given by nPr where n> r
Total number is 13 and required number is 2
n= 13 and r= 2
13 P2= 156 possible combinations.
A combination is any subset of the objects r selected without regard to their order, from the set of n distinct objects. It is given by nCr where n> r
Answer:
28/45
Step-by-step explanation:
tan = opp/adj
tanE = 28/45
Step-by-step explanation:
The perpendicular distance between the chord and the center of the circle forms a right triangle with the chord and the radius. Using trig:
sin 30° = x / (D/2)
sin 30° = 2x / D
1/2 = 2x / D
x = D/4
I believe its the first one
--y<2/3--
Slope - up 2 over 3
dotted line because there is no or equal to
y< so shade down
--y>/=-x+2--
Negative slope
or equal to so solid line
y intercept 2
Y> shade up
It’ll also be 130! BECUASE it is paralell
