Let S be the set of outcomes when two distinguishable dice are rolled, let E be the subset of outcomes in which at least one die
ExtremeBDS [4]

Answer:

Step-by-step explanation:

given that S be the set of outcomes when two distinguishable dice are rolled, let E be the subset of outcomes in which at least one die shows an even number, and let F be the subset of outcomes in which at least one die shows an odd number

E = atleast one shows even number

i.e. both cannot show odd number

So elements of E are

E ={(1,2) (1,4) (1,6) (2,1) (2,2) (2,3) (2,4)( 2,5) (2,6) (3,2) (3,4) (3,6) (4,1) (4,2) (4,3) (4,4( 4,5) (4,6) ,5,2) (5,4) (5,6) (6,1) (6,2) (6,3) (6,4( 6,5) (6,6) }

F = atleast one die shows odd

F={(1,1) (1,2) (1,3), (1,4)(1,5) (1,6) (2,1)  (2,3) ( 2,5) (3,1) (3,2) (3,3) (3,4)( 3,5) (3,6) (4,1) (4,3) (4,5) (5,1)  (5,2) (5,3)(5,4) (5,5) (5,6) (6,1)  (6,3)( (6,5) }

HELP PLS MANY POINTS Use the function f(x) to answer the questions: f(x) = 4x2 + 8x − 5 Part A: What are the x-intercepts of the
Andrei [34K]

Answer:

see below

Step-by-step explanation:

f(x) = 4x^2 + 8x − 5

To find the x intercepts set y = 0

0 =4x^2 + 8x − 5

Factor

0=(2x-1)(2x+5)

Using the zero product property

2x-1 =0     2x+5 =0

2x=1            2x = -5

x = 1/2           x = -5/2

The x intercepts are ( 1/2 ,0)   and ( -5/2,0)

Rewriting in vertex form by completing the square

4 ( x^2 + 2x) -5

4 ( x^2+2x +1) -4*1 -5

4 ( x+1) ^2 -9

Vertex form is

a( x-h) ^2 +k  where ( h,k) is the vertex

The vertex is ( -1,-9)

We know it opens upwards since a > 0

Plot the vertex and the x intercepts

The graph is symmetric on  based on the vertex
