Answer:
1.2
Step-by-step explanation:
Since (3 + 6 + 4 + x + 7)/5 = 5, then 3 + 6 + 4 + x + 7 equals 25. Adding, we have 20 + x = 25. Thus x = 5. Now we calculate how far each number is from the mean. 3 is 2 away. 6 is 1 away. 4 is also 1 away. 5 is 0 away, and 7 is 2 away. Now, we have to find the mean of this. (2 + 1 + 1 + 0 + 2 ) / 5 is equal to 6/5, which is 1.2
