The mean is 4.93333 (3 is repeating)
Explanation
So mean is just the sum of the numbers divided by the number of terms
So we would solve this by adding up all terms as shown here
10.6 + 4 + 4 + 6 + 4 + 1 = 29.6 = sum
Then we will divide the sum by the number of terms which is 6 in this case to get our mean as shown here
29.6 / 6 = 4.9333
The mean is 4.9333 (3 is repeating)
Answer:
The answer is A (-3,4,6).
Step-by-step explanation:
1 Solve for z in -3x-4y+z=-1
z=3x-1+4y
2 Substitute z=3x-1+4y into 2x+y-z=-8
-x-3y+1=-8
3 Substitute z=3x-1+4y into x+8y-z=23
-2x+4y+1=23
4 Solve for x in -x-3y+1=-8
x=-3y+9
5 Substitute x=-3y+9 into z=3x-1+4y
z=-5y+26
6 Substitute x=-3y+9 into -2x+4y+1=23
10y-17=23
7 Solve for y in 10y-17=23
y=4
8 Substitute y=4 into z=-5y+26
z=6
9 Substitute y=4 into x=-3y+9
x=-3
10 Therefore,
x=-3
y=4
z=6
