Answer:

Step-by-step explanation:
To determine the slope, divide the rise by the run to calculate the slope.
Note that
1 ft = 12 in
Let
y ----> the rise
x ----> the run
m ----> the slope

the values are given as



substituting these values gives


Simplifying further

Answer: a)
b) 
Step-by-step explanation:
a) To achieve an even total, there are 3 possible combinations:
1) Even, Even, Even, Even 
2) Even, Even, Odd, Odd
3) Odd, Odd, Odd, Odd 
Order is irrelevant
Summing these yields your final result: 
b) If one die shows a 2 and another a 3, while the remaining two can show any digits, there’s only one way to get a 2, one way for a 3, and six potential numbers for each of the other two dice.

The question requires completion since the inventory data is absent.
Answer:
0.8753
Step-by-step explanation:
Determine the likelihood that your job will complete before 10:01 am.
In this scenario, the expected value of an Exponential distribution is E(X)=12.
To find the probability for the third job, we apply the Poisson Distribution with a parameter of 1/λ.
This gives us E(Y) =1/12.
Since the third job is expected to be ready by 10:01 AM, we have E(Y)=61/12.
Hence, the probability sought is

=1- POISSON(3,5,true)
=1-0.1246
=0.8753
