Using a discrete probability distribution, it is found that there is a 0.15 = 15% probability that it will take more than 9 minutes for all the customers currently in line to check out.
<h3>What is the discrete probability distribution?</h3>
Researching the problem on the internet, it is found that the distribution for the number of customers in line at the store is given by:
Hence, since each customer takes 3 minutes to check out, the probability that it will take more than 9 minutes for all the customers currently in line to check out is the probability that there are more than 3 customers, hence:
P(X > 3) = P(X = 4) + P(X = 5) = 0.10 + 0.05 = 0.15.
0.15 = 15% probability that it will take more than 9 minutes for all the customers currently in line to check out.

8m board
--------
One piece has to be longer by two so this is what i would do:
--------
1. 8 divided by 2 = 4
2. so i will take two off the 4 and get 2
3. so the two pieces will be 2 and 6
4. 2+6 = 8
Hope this helped!

Answer:
Step-by-step explanation:
#3 slope is the change in y divided by the change in x
So -10-(-8)/13-15 = -2/-2=1
for #5 the slope is always the coefficient of x when written in slope intercept form so the slope is 3
#7 the gradient is infinite
Answer:
(1) or A or whatever lol
Step-by-step explanation:
basically just plug the number in, set them equal to each other, and see if the equation is true...
1/2(-2)+3=|-2|
-1+3=2
2=2
1/2(2)+3=|2|
1+3=2
4=2
1/2(3)+3=|3|
1.5+3=3
4.5=3
1/2(-6)+3=|-6|
-3+3=6
0=6
the only one that is a true statement is x=-2
R= 18
d=r(2)
36=r(2)
36/2=r(2)/2
18=r
