What is the average (arithmetic mean) of eleven consecutive integers? (1) the average of the first nine integers is 7. (2) the a

laiz [17]

Since eleven is odd, there must be a centra element, which in this case is the sixth. So, we can write 11 consecutive integers as

$x-5, x-4, x-3, x-2, x-1, x, x+1, x+2, x+3, x+4, x+5$

Since the arithmetic mean is the sum of the values, divided by how many they are, we have

$M = \dfrac{x-5, x-4, x-3, x-2, x-1, x, x+1, x+2, x+3, x+4, x+5}{11} = \dfrac{11x}{11} = x$

So, the mean of 11 consecutive integers is the 6th integer.

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

schepotkina [342]

Answer:

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

$YYYY - EEE + AA - R = 1234$ .

From LHS,

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

$2222-999+11-0\\=\ 1223\ + 11\\=\ 1234$

=RHS

$Therefore\ the\ value\ of \ Y, E, A, R\ is\ 2\ , \ 9 , \ 1\ and\ 0$
