Cars enter a car wash at a mean rate of 2 cars per half an hour. what is the probability that, in any hour, exactly 5 cars will enter the car wash? round your answer to four decimal places.

  0.1563

Step-by-step explanation:

The Poisson distribution probability formula is given by :-

, where is the mean of the distribution and x is the number of success

Given : Cars enter a car wash at a mean rate of 2 cars per half an hour.

In an hour, the number of cars enters in car wash =

Now, the probability that, in any hour, exactly 5 cars will enter the car wash is given by :-

Therefore, the required probability = 0.1563

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!
