Answer:
39.10%
Step-by-step explanation:
The given timeout distributions are:
Exp (1/10), Exp (1/12)
The equation to use is the following:
F (x) = 1 - e ^ (- a / b); x> 0
So the probability is:
P (food has not arrived after waiting 25 minutes | R) = e ^ (- 10/10) = 0.3679
P (food has not arrived after waiting 25 minutes | S) = e ^ (- 12/15) = 0.2865
So:
P (food has not arrived after waiting 25 minutes) = (food has not arrived after waiting 25 minutes | R) * P (R) + (food has not arrived after waiting 25 minutes | S) * P (S)
Replacing:
P (food has not arrived after waiting 25 minutes) = 0.3679 * 1/3 + 0.2865 * 2/3 = 0.3136
However:
P (R | food has not arrived after waiting 25 minutes) = (food has not arrived after waiting 25 minutes | R) * P (R) / P (food has not arrived after waiting 25 minutes)
P (R | food has not arrived after waiting 25 minutes) = 0.3679 * 1/3 / 0.3136 = 0.3910
It means that the probability is 39.10%
Answer:
x≤-3 or 2≤x∠7

It would be the first answer on the paper
Your answer to this question that you have asked is three dollars =. 3$
$3.00
Given:
x y
2 3
7 3
7 10
2 10
It is easier to graph these vertices to avoid confusion.
Length: basis is the y-values : 10 - 3 = 7 units
Width: basis is the x-values: 7-2 = 5 units
Area = Length * Width
A = 7 units * 5 units
A = 35 units² Choice D.
times
equals 1
Solution:
Given expression is at what times
equals the whole.
Whole means 1 in a fraction.
Let us take the number of times be x.

Multiply by
on both sides of the equation.





Hence the fraction
times
equals 1.
