Answer:
Principal = $500
Interest = $37.50
Rate = 0.025 = 2.5%
Time = 3 years
Step-by-step explanation:
The formula for simple interest is I = PRT ÷ 100
Casandra's equation = I= 500(0.025)(3)=$37.50
Principal = $500
Interest = $37.50
Rate = 0.025 = 2.5%
Time = 3 years
First, we separate all instances of t by subtracting J from both sides:
F = J + Jrt
F - J = Jrt
Then, we separate the t by dividing both sides by Jr:

Therefore, t is equal to (F - J) ÷ Jr
Answer:
Population is 34000 students
Sample is 770 students
Step-by-step explanation:
Population :In statistics, a population is the entire pool from which a statistical sample is drawn.
Sample: A sample refers to a set of observations drawn from a population.
We are given that 34,000 students attended the university.
Out of which a random sample of 370 male students and 400 female students was selected
So, Total students selected = 370+400=770
So, Population is 34000 students
Sample is 770 students
So, Option C is true.
