A) The amount of change held by a teacher at the end of each day for a year.
Step-by-step explanation:
A normal distribution has a bell-shaped density curve described by its mean and standard deviation.
A) The amount of change held by a teacher at the end of each day for a year - This is probably near normal because the teacher cannot have negative cents in her or his pocket.
First, we can start off with a fraction:
9/36 = 1/4
Now that we have this fraction, we multiply by 25:
25/100
This can be changed into a percent:
25%
100 - 25 = 75
25% is alcohol and 75% is water
Answer:
The principal is $4,150.
Step-by-step explanation:
We have to find the principal if the maturity value is $4,500 and the simple interest is $350.
<u>As we know that the formula for calculating the final amount or maturity amount is given by;</u>
Amount = Principal + Interest
Here, Simple interest = $350
Amount or Maturity value = $4,500
So, the Principal = Amount - Interest
Principal = $4,500 - $350
= $4,150
Hence, the principal if the maturity value is $4,500 and the simple interest is $350 is $4150.
