Answer:
x=10.247
y=52.02
z=37.98
Step-by-step explanation:
For x you use Pythagorean theorem which, in this situation would be 13^2=8^2+x^2 rearranging this we can figure out x by taking the square root of 13^2-8^2.
For y you can use any trig function but I chose to use cos since that uses info we're given, to find y you just do the inverse cos or cos^-1 of 8/13 to find the angle
For z you can use any trig function but I chose to use sin since that uses info we're given, to find z you just do the inverse sin or sin^-1 of 8/13 to find the angle
Answer:
(d) 1/√(s³)
Step-by-step explanation:
The expression can be simplified by making use of the rules of exponents.
<h3>Rules of exponents</h3>
The relevant rules are ...
![a^b\cdot a^c=a^{b+c}\\\\(a^b)^c=a^{bc}\\\\\left(\dfrac{a}{b}\right)^c=\dfrac{a^c}{b^c}\\\\a^{b/c}=\sqrt[c]{a^b}](https://tex.z-dn.net/?f=a%5Eb%5Ccdot%20a%5Ec%3Da%5E%7Bb%2Bc%7D%5C%5C%5C%5C%28a%5Eb%29%5Ec%3Da%5E%7Bbc%7D%5C%5C%5C%5C%5Cleft%28%5Cdfrac%7Ba%7D%7Bb%7D%5Cright%29%5Ec%3D%5Cdfrac%7Ba%5Ec%7D%7Bb%5Ec%7D%5C%5C%5C%5Ca%5E%7Bb%2Fc%7D%3D%5Csqrt%5Bc%5D%7Ba%5Eb%7D)
<h3>Application</h3>

Hope this helps!
<span>Yes, the two events are independent because P(NF|PB) = P(NF).
I'm not 100% sure though so wait til someone else answers :)</span>
