Answer:
15.75
Step-by-step explanation:
So we know 5% is 1/20 out of 100 (20x5=100) so then we need to set up the equation to find how much 5% of 15 is. Which is .75 cents. So we then add the 75 cents to the already $15 shipping fee to get an answer of 15 dollars and seventy five cents.

Answer:
The value of car after 14 years is $ 2,363.04
Step-by-step explanation:
Given as :
The price of new car = N = $ 18,000
The rate of depreciation of the value of the car = R = 13.5 % per year
Let The value of car after 14 years = $ x
The time period = 14 years
<u>Now, According to question</u>
The value of car after n years = initial value of car × 
or, $ x = N × 
or, $ x = $ 18,000 × 
Or, $ x = $ 18,000 × 
∴ x = $ 18,000 × 0.13128
I.e x = $ 2,363.04
So, The value of car after 14 years = x = $ 2,363.04
Hence The value of car after 14 years is $ 2,363.04 Answer

Step-by-step explanation:
Answer: Mean = 52.8 mins
Step-by-step explanation:
We have lapses of 30 minutes, so we can write the average for each, this means that:
0 < t < 30 can be averaged to the middle of the range: 15 min.
Doing this, we have that:
7 students 15 min
27 students 45 min
12 students 75 min
4 students 105 min.
Now we can calculate the mean:
mean = (x1*n1 + x2*n2 + ...)/N
where x1 is the amount of time 1, and n1 is the number of students associated to that time and so on. N is the total number of students
Mean = (7*15min + 27*45min + 12*75min + 4*105min)/(7 + 27 + 12 + 4)
Mean = 52.8 mins
