What is the area of a circle with radius 6 cm? Give your answer in terms of 2 points

What does it mean when a question number is circled in a textbook

RoseWind [281]

This is only my opinion. I could be wrong.

My guess is:

Somebody else used that book before you, maybe last year or
the year before, and it was somebody who didn't mind writing
in his book.

One day he didn't have time to write down the homework in his
assignment notebook, so he just circled the homework problems
in his textbook.

A student's course grade is based on one midterm that counts as % of his final grade, one class project that counts as % of

Andrei [34K]

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:

$Midterm = 15\%$

$Project = 25\%$

$Assignment = 40\%$

$Exam = 20\%$

Scores

$Midterm = 66$

$Project = 90$

$Assignment = 75$

$Exam = 66$

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:

$Overall = 15\% * 66 + 25\% * 90 + 40\% * 75 + 20\% * 66$

$Overall = 9.9 + 22.5 + 30 + 13.2$

$Overall = 75.6$

Solving (b): The letter grade

From the question, we have:

$A: Mean \ge 90$

$B: 80 \le Mean < 90$

$C: 70 \le Mean < 80$

The overall score falls in the following category:

$C: 70 \le Mean < 80$

Because:

$70 \le 75.6 < 80$

Hence, the letter grade is C

We can factor a polynomial by finding its roots. In particular, a quadratic equation has (at most) two roots $x_1,\ x_2$ , which would allow us to write the polynomial as
