The answer is 14 you just have to substitute x with the given number and finish the equation
Perimeter is 2(2x+5)+2(x-2) which is 4x+10+2x-4 which is in turn 6x+6. 6x+6 is the perimeter. Hope I helped!
3(y-9)-y=7
3y - 27 -y = 7
2y = 34
Y = 17
3(x) -17 = 7
3x = 24
X = 8
Answer:
Value of a is 0.667
Step-by-step explanation:
We are given the following in the question:
The rate of customer at an airport follows a Poisson distribution with
The normal approximation of Poisson distribution can be done in the following manner
Formula:
We have to find the value of a such that
More than 50 customers per 5 hours means more than 10 customer per hour.
Thus, we can write
Therefore, value of a is 0.667
