To find the y-intercept of the equation, we will put 0 in for x, and find y.
So, y = 14.2 - 3.9(0)
y = 14.2
Answer:
a) Destiny can run 1 mile is 6 minutes.
b) Destiny can walk back 1 mile is 16 minutes.
Step-by-step explanation:
The running rate of Destiny is

So, she runs 1 mile in
= 6 minutes
Hence, Destiny can run 1 mile is 6 minutes.
The walking rate of Destiny is

So, she walks 1 mile in
= 16 minutes
Hence, Destiny can walk back 1 mile is 16 minutes.
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.
