50%. Idk I think. I guess so lol
Let 
denote the number of packages brought by customer 
. If, for instance, 
customers are in line, then the total number of packages is 
, and
since the number of packages brought by any customer is independent from the number of packages brought by any other.
a. 
is the probability that a total of 3 packages are waiting to get wrapped from among a total of 3 customers. This means each customer must have exactly one package. So
b. 
is the probability that a total of 11 packages are brought by 4 customers. The only way for there to be 11 packages is if 3 customers bring 3 packages and the last 1 brings 2. There are 
ways this can happen, so
So we find what's called the GCF or greatest common factor
firest we find teh factors and group the like ones
40=2 times 2 times 2 times 5
20=2 times 2 times 5
we see a common set of numbers which is in both which is 2 times 2 times 5=20
biggest number that can go into both 40 and 20=20
Answer:
a) y-intercept is 4000
b)T(18)=5710
Step-by-step explanation:
a) This is the equation of a line with slope 95 and y-intercept 4000.
The y-intercept represents the basic amount the student has to pay even if not taking any unit: $4000
b) T(18) represents the total amount to be paid by a student who is taking 18 units: T(18) = 4000 + 95*18 = 4000 + 1710 = 5710
So a total tuition of $5710
