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).
Answer:
Step-by-step explanation:
This is a geometric mean problem...a ratio. The geometric mean is the height of the triangle, 6. To solve:
and cross multiply to solve for x:
3x = 36 so
x = 12
the first part isn't 90, it's 180.
the whole circle is 360, half of 360 is 180
an acute angle is any angle less than 90 degrees.
Answer:
a) At rest
Step-by-step explanation:
25N+25N=50N
therefore, 50N is applied from both the sides
So, 50N - 50N = 0
the, net value is zero, here.
