The total number of arrangements for all of them to be women is:
C(7, 4) because the order does not matter; we'd still have the same arrangements.
Now, we can simplify this:




Now, the total number of arrangements, without restriction, is simply: C(12, 4) because we don't care who we pick.
Answer: 14
Step-by-step explanation:
- Degrees of freedom is the number of values in the evaluation of a test statistic that are free to vary.
For t-statistic , the degree of freedom for a sample with sample size 'n' is given by :-

Given : Sample size : n-1
Then, the number of degrees of freedom the t-value will have :-

Hence, the t-value will have 14 degrees of freedom.

The hypotenuse is the longest side of the triangle. The opposite is the side that is across from a point/angle. The adjacent is the side next to a point/angle.
At ∅ (pretend that's theta LOL), 17 is the hypotenuse, 8 is the opposite side, and 15 is the adjacent side.
So:
sin ∅ = Opposite/Hypotenuse
sin ∅ = 
cos ∅ = Adjacent/Hypotenuse
cos ∅ = 
tan ∅ = Opposite/Adjacent
tan ∅ = 
1/8
Explanation:
Volume of a cube formula: V=s^3 or s•s•s
s=1/2
V= (1/2)^3
=1/8
