Answer:
To calculate final grade we use the formula:
Final grade = H( the weight of h) + Q( the weight of q) + P (the weight of project) +T (the weight of test) + F(the weight of final exams).
This formula help us to calculate the grade we need to get.
Step-by-step explanation:
Solution:
Suppose grade breakdown for certain college course is as follow:
Homework = 15%
Quizzes = 20%
Project = 10%
Test = 40%
Final exam= 15%
Let G represent the final grade
H represents homework average,
Q represents quizzes and P represent project, T represent test average and F represent final exam.
To calculate final grade we use the formula:
Final grade = H( the weight of h) + Q( the weight of q) + P (the weight of project) +T (the weight of test) + F(the weight of final exams).
This formula help us to calculate the grade we need to get.
Answer:
The margin of error for a sample size of 250 is 6
Step-by-step explanation:
The margin of error is given as
1/square root of the sample size
Thus, margin of error for a sapless size of 250 is
1/√250
= 1/15. 811
= 6
See attached picture for solution:
Answer: B) A = 750(1.04)ⁿ
<u>Step-by-step explanation:</u>
The formula for compounded annually is: A = P(1 + r)ⁿ where
- A (amount accrued) = <em>unknown</em>
- P (amount invested) = $750
- r (interest rate) = 4% -->(0.04)
- t (time in years) = <em>unknown</em>
A = 750(1 + 0.04)ⁿ
= 750(1.04)ⁿ
