Answer:

The value of the 6th item is 10

Step-by-step explanation:

If the mean of 6 items is 8, the total sum of all 6 numbers is 48. We add up all of the other numbers: 5 + 9 + 11 + 6 + 7 = 38. This means our 6th item, x, fits the equation 38 + x = 48. x = 10.

Answer:

The 6th item is 10

Step-by-step explanation:

[] Mean is basically the average. Add all the numbers together and divide by number of numbers.

We can set up the following and solve for your answer:

[Equation] [tex]\frac{5+ 9+11+6+7+x}{6} =8[/tex]

[Multiply both sides by 6] [tex]5+ 9+11+6+7+x =48[/tex]

[Combine like terms] [tex]38+x=48[/tex]

[Subtract 38 from both sides] [tex]x = 10[/tex]

Have a nice day!
