A​ student's course grade is based on one midterm that counts as ​% of his final​ grade, one class project that counts as ​% of his final​ grade, a set of homework assignments that counts as ​% of his final​ grade, and a final exam that counts as ​% of his final grade. His midterm score is ​, his project score is ​, his homework score is ​, and his final exam score is . What is his overall final​ score? What letter grade did he earn​ (A, B,​ C, D, or​ F)? Assume that a mean of 90 or above is an​ A, a mean of at least 80 but less than 90 is a​ B, and so on.

Answers

Answer:

The overall score is 75.6

Letter grade is C

Step-by-step explanation:

The question has missing details (See comment section for complete question).

From the complete question, we have:

Proportion:

[tex]Midterm = 15\%[/tex]

[tex]Project = 25\%[/tex]

[tex]Assignment = 40\%[/tex]

[tex]Exam = 20\%[/tex]

Scores

[tex]Midterm = 66[/tex]

[tex]Project = 90[/tex]

[tex]Assignment = 75[/tex]

[tex]Exam = 66[/tex]

Solving (a): The overall score

To do this, we simply calculate the mean of the given data.

The mean is calculated by multiplying each proportion by the scores..

So, we have:

[tex]Overall = 15\% * 66 + 25\% * 90 + 40\% * 75 + 20\% * 66[/tex]

[tex]Overall = 9.9 + 22.5 + 30 + 13.2[/tex]

[tex]Overall = 75.6[/tex]

Solving (b): The letter grade

From the question, we have:

[tex]A: Mean \ge 90[/tex]

[tex]B: 80 \le Mean < 90[/tex]

[tex]C: 70 \le Mean < 80[/tex]

The overall score falls in the following category:

[tex]C: 70 \le Mean < 80[/tex]

Because:

[tex]70 \le 75.6 < 80[/tex]

Hence, the letter grade is C

Part of the population of 5,500 elk at a wildlife preserve is infected with a parasite. A random sample of 50 elk shows that 6 of them are infected. How many elk are likely to be infected? Based on the sample, there will likely be infected elk in the wildlife preserve.​

Answers

Answer:

5444

Step-by-step explanation:

5,500-50=5,450

5,450-6=5,444

Answer:

x = 660

Step-by-step explanation:

Solve

Write the proportion where x is the number of infected elk

6/50 = x/5,500

Cross multiply

5500 ÷ 50 = 1100 x 6

x = 660
