Step-by-step explanation:
Hello
I believe there is an error in the question
we have two equations and need to find x and y
let s multiply by 8 so that we can get rid of the fractions
(1) becomes 2x+4y=5
(2) becomse 6x-4y=9
if we sum it gives
2x+4y+6x-4y=9+5
8x=14
x = 14/8 = 7/4
and then from the first equation
4y = 5 - 7/4
<=> 16y = 20-7 = 13
y = 13/16
the solutions is (7/4,13/16)
Answer:
a) X = 2/15 , 8/15, 1/3
b) attached below ( probability plot )
C) F(x ) attached below
d) cumulative probability plot
Step-by-step explanation:
a) Determine the probability of Function X
P( x = 0 ) = 6 / 45 = 2 /15 = 0.1333
P( x = 1 ) = 8/15 = 0.5333
P( x = 2 ) = 1/3 = 0.3333
Hence the probability of Function X = 2/15 , 8/15, 1/3
b) Graph of the probability Function of X
x 0 1 2
p(x) 0.1333 0.5333 0.3333
attached below is the plot ( probability plot )
<u>c) Determine the Distribution function of CX </u>
using the results achieved in part ( a )
attached below is the solution
<u>d) Graph of distribution function of X </u>
x 0 1 2
p(x) 0.1333 0.6667 1
attached below is the plot ( cumulative probability plot )
Answer:
Options (1) and (2)
Step-by-step explanation:
Let the proportional relation between x and y is represented by,
y ∝ x
y = kx
Here, k = Proportionality constant
Option 1,
From the given table,
Graph of the points given in the table passes through origin.
For x = 0, y = 0.
For x = 1 and y = 9,
k =
k = 9
For x = 2 and y = 18,
k =
k = 9
Therefore, table represents a proportional relation.
Option 2.
From the given table,
Graph of the points given in the table passes through origin.
For x = 3 and y = 21,
k =
k = 7
For x = 6 and y = 42,
k =
k = 7
Therefore, table represents a proportional relation.
Option 3.
From the given table,
For x = 0, y = 1
But for the proportional relation graph should pass through origin (0, 0).
Therefore, table doesn't represent a proportional relation.
Option 4.
From the table given,
For x = 0, y = 2
Graph of the line doesn't pass through the origin (0, 0)
Therefore, table doesn't represent a proportional relation.
Options (1) and (2) are the correct options.
