Answer:

n = 3

Step-by-step explanation:

subtract 1 from both sides to get:

-4n + 6 = -2n

then add 4n to both sides to get:

6 = 2n

then divide both sides by 2 to get:

3 = n

102,119,107,113,110, x; mean 114
Rom4ik [11]

Answer:

x = 133

Step-by-step explanation:

First, determine what total sum would be needed for the mean to be 114. Do this by multiplying 114 by 6 (bc total number of values in data set includes the variable <em>x</em>).

114 x 6 = 684

Next, add the five known values to get a sum of 551.

Now, just: 684 - 551 = 133

For the mean to be 114, x must equal 133.
