Step-by-step explanation:
All the 5 rows of the coefficient matrix (since it is of order 5×8) will have a pivot position. The augmented matrix obtained by adding a last column of constant terms to the 8 columns of the coefficient matrix will have nine columns and will not have a row of the form [0 0 0 0 0 0 0 0 1]. So the system is consistent.
Answer:
47.73% probability that it takes Renee at most 29 minutes to go grocery shopping
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that we find a value X lower than x is given by the following formula.

Uniformly distributed between 18.5 minutes and 40.5 minutes.
This means that 
What is the probability that it takes Renee at most 29 minutes to go grocery shopping

Answer: x = 22
Step-by-step explanation:
We must isolate the x by itself.
We need to add 5 to both sides of the equation so it cancel out from the side with x.
So x = 22
