Answer:
0.101
Step-by-step explanation:
Given that :
Standard deviation, s = 0.2
Sample variance, s² = 0.0653
Sample size, n = 10
Population variance = σ² = 0.04
We use the Chi square distribution :
(n - 1)s² / σ²
For P(s² ≥ 0.065)
(n - 1)s² / σ² = (10 - 1)*0.0653 / 0.04
(n - 1)s² / σ² = 0.585 / 0.04 = 14.625
P(s² ≥ 14.625) = 0.101 ( chi squee calculator).
Henry would be able to write 14 pages of a novel in 8 hours.
5 1/4(or 5.25)/3=1 3/4 (or 1.75)
1 3/4 x 8 =14
Hope This Helps!

It is 8.525. what u do is 21÷40 and get .525 and then u add the 8 in the front and get 8.525
So I believe you will have to do 10% x 7 as it has been seven years which will be 70% and 70% of 8000 is 5600 so the answer will be £5600
