Answer:
<u>The taxi ride was for 23 miles.</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Function of total cost (C)ₙ = 10 + 1.50n
n = Miles of the taxi ride
C = Cost in dollars of the taxi ride
Total cost = $ 44.50
2. For how many miles was the taxi ride?
Let's replace the cost of the taxi ride in the function given for solving for n, this way:
10 + 1.50n = 44.50
1.50n = 44.50 -10
1.50n = 34.50
n = 34.50/1.50
n = 23
<u>The taxi ride was for 23 miles.</u>
We are interested in the left-end area under the standard normal curve that has the area 0.025.
But the problem seems to be simpler than that:
If n = number of students in the class, and we know that 2.5% of these students failed the course, and that 5 failed, then we can surmise that
0.025n = 5. Solving for n by multiplying both sides by 40, we get n = 200.
There were 200 students in the class.
It is perfectly fair for a teacher to put more info into a problem statement than you really need to solve the problem. That seems to be what happened here.
What you need to do is subtract since the key word "How much Less money" is in it.
$9.956-$50 = 40.044$
I dont know all of them, but I know P stands for principal amount (what you start with), t stands for the amount of time it takes in years, and I think r is the rate anually that money is made
This function is increasing, so the slope should be positive.
slope=rise/run=2/3
