Answer:
∠AB=9
Step-by-step explanation:
<em>the pyagrothyes therom= </em>
<em>+</em>
<em>=</em>
<em>to find ∠AB we need to find the height of the triangle.</em>
<em>replace the variables:</em>
<em>+</em>
<em>=</em>
<em>=</em>
<em>-</em>
<em>=</em>
<em>simplify:</em>
<em>81-36=</em>
<em>now we solve for ∠AB</em>
<em>replace the variables:</em>
<em>+</em>
<em>=</em>
<em>simplify:</em>
<em>36+45=</em>
<em>=9</em>
I hope this helps you!!
have a nice day!!
Answer:
The distribution is 
Solution:
As per the question:
Total no. of riders = n
Now, suppose the
is the time between the departure of the rider i - 1 and i from the cable car.
where
= independent exponential random variable whose rate is 
The general form is given by:

(a) Now, the time distribution of the last rider is given as the sum total of the time of each rider:


Now, the sum of the exponential random variable with
with rate
is given by:

Answer:
c 2:1
Step-by-step explanation:
8/4=2
4/4=1
8:4 simplified is 2:1
