Hi!
The answer to your question is 9.75 minutes
Here is the math to prove it:
9+11+3+14+14+7+14+6=78
Now you will take 78 and divide it by 8
This is because when finding the mean you add all of the given number together and then divide them by the amount of number added together.
78/8=9.75
Thus, your answer is 9.75 minutes
I hope this helped!
Have a wonderful day/night!
God bless!

Answer:
∛188 ≈ 5.72865
Step-by-step explanation:
Any scientific or graphing calculator or spreadsheet can tell you the cube root of 188.
∛188 ≈ 5.72865431598...
__
You know that 5³ = 125 and 6³ = 216, so the root will lie between 5 and 6, closer to 6. As a first approximation, you can figure it is about ...
x = ∛188 ≈ 5 + (188-5³)/(6³ -5³) = 5 + 63/89 ≈ 5.71
You can figure this much using a 4-function calculator.
A closer approximation (x') can be had using the iteration formula ...
x' = (2x³ +188)/(3x²)
For x = 5.71, the value of x' is ...
x' ≈ (2×5.71³ +188)/(3×5.71²) ≈ 560.3388/97.8123 ≈ 5.7287
This value is correct when the root is rounded to 4 decimal places. Another execution of the iteration formula using this value will give the root accurate to 9 decimal places.
You have to find the value of c when b=4/3and a=6
