Answer:
The amount in Brooke's lunch account change by the end of that week is $-20 or $20 decrease.
Step-by-step explanation:
Consider the provided information.
Each day Brooke buys lunch and withdrawn the same amount i.e $4.
The number of days are 5.
To calculate the change by the end of that week, find the total amount withdrawn in 5 days.
To represent withdrawn use a negative sign.
The product of the numbers will be a negative number as they have opposite sign.
Hence, the amount in Brooke's lunch account change by the end of that week is $-20 or $20 decrease.

Answer:
90.91% probability that a car needs an oil change given that it has a certain factory defect
Step-by-step explanation:
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this problem, we have that:
Event A: having a factory defect.
Event B: needing an oil change.
The probability that a car has a certain factory defect is 825.
So 
The probability that a car has a certain factory defect and needs an oil change is 750.
So 
What is the probability that a car needs an oil change given that it has a certain factory defect
90.91% probability that a car needs an oil change given that it has a certain factory defect
12x2=24
The middle is extra. All you need to answer is the $12 is half his allowence left.
