Answer:
the probability having no customers are in the system is 0.375
Step-by-step explanation:
The computation of the probability having no customers are in the system is as follows;
Given that the arrival rate is 1.25 customers per minute
The Service rate is 2 customers per minute
Based on the above information, the probability is

Hence, the probability having no customers are in the system is 0.375
Since they are similar triangles, they are just enlarged versions of each other. This means that the left-most angle of triangle XYZ is also 35°.
Angles in a triangle add up to 180°, so we can find the missing angle by subtracting the two known angles from 180.
180 - 70 - 35 = 75
The right-most angle of triangle XYZ would be 75°.

Formula for trapezoid area is A=b1+b2 x heightx 1/2 so your answer would be 161m squared
Answer:
Step-by-step explanation:
It is given that an isosceles triangle has two sides of length a and base b, then the perimeter of an isosceles triangle= Sum of all the sides
⇒a+a+b=15.7
⇒2a+b=15.7
⇒b=15.7-2a
Also, we know that he sum of the lengths of any two sides of a triangle must be greater than the length of the third side that means,
⇒a+a>b
⇒2a>b
Now, substituting the value of b in the above equation, we get
2a>15.7-2a
⇒4a>15.7
⇒a>3.925
Now, b=15.7-2a, therefore b=15.7-2(3.925)=15.7-7.85=7.85
Thus possible value of b is 7.85.
