Find all possible values of the digits Y, E, A, R if - EEE + AA - R = 1234, and different letters represent different digits.

Y:  2

E:  9

A:  1

R:  0

Step-by-step explanation:

If we used the value  Y = 2,   E = 9  , A = 1  and R = 0

in the given equation i.e

.

From LHS,

Putting the value of Y,E, A and R in the given question we get

=RHS

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
