30 * 1/5 = 6 so 6 have a cell phone
1/2 * 6 = 3 so 3 have a cellphone and social media
195 divide by 2 1/2

he is paying 26 cents for each load
Answer:
“A random variable is one whose values describe the outcome of some chance process”
Step-by-step explanation:
Roughly speaking, a random variable is a function whose values depend on outcomes of a random phenomenon.
The phenomenon could be an experiment created by human beings, a natural process or any other kind of event that produces results that cannot be foreseen with a deterministic model like a differential equation or formula of any kind.
<em>
The random variable must also be a measurable function. </em>
Since its value cannot be predicted in a deterministic way, we usually approximate its possible values with probabilistic measures.
So, from the possible choices of answer, the one that fits the best is
“A random variable is one whose values describe the outcome of some chance process”
Use the law of sines
11/sin50°=13/sinθ
11/0.766=13/sinθ
11sinθ=13(0.766)
11sinθ=9.958
sinθ=9.958/11
sinθ=0.9052727
use arcsin on your calculator
θ=64.86°
