Answer: hi
Step-by-step explanation:
Answer:
#1 is 31°
#2 is 120°
Step-by-step explanation:
You know that a triangle is 180°. In the first one its a right triangle, which means that angle is 90°. Subtract 90 and 59 by 180. The second subtract 36 and 24 by 180 to get your answer.
Answer:
that is what it would look like
Hope it helps!❤❤
Answer:
Sec(x)
Step-by-step explanation:
Tan(x) = Sin(x)/Cos(x)
Csc(x) = 1/Sin(x)
Sin(x) 1
--------- . ---------
Cos(x) Sin(x)
Sin(x) cancel
1
--------- =
Cos(x)
Sec(x)
Answer:
The shape and rate parameters are
and
.
Step-by-step explanation:
Let <em>X</em> = service time for each individual.
The average service time is, <em>β</em> = 12 minutes.
The random variable follows an Exponential distribution with parameter,
.
The service time for the next 3 customers is,
<em>Z</em> = <em>X</em>₁ + <em>X</em>₂ + <em>X</em>₃
All the <em>X</em>
's are independent Exponential random variable.
The sum of independent Exponential random variables is known as a Gamma or Erlang random variable.
The random variable <em>Z</em> follows a Gamma distribution with parameters (<em>α</em>, <em>n</em>).
The parameters are:
![\alpha =\lambda=\frac{1}{12}\\n=3](https://tex.z-dn.net/?f=%5Calpha%20%3D%5Clambda%3D%5Cfrac%7B1%7D%7B12%7D%5C%5Cn%3D3)
Thus, the shape and rate parameters are
and
.
