Pie chart

Step-by-step explanation:

Given that a professor has kept records on grades that students have earned in his class

He wants to examine the percentage of students earning the grades A, B, C, D, and F during the most recent term,

We have to find which kind of plot could he make

Box plot gives comparison for interval of scores this is to some extent helpful to find out the percentage of students getting a range of scores

Timeplot is irrelevant here. Dot plot will not be of much use.

Histogram is to some extent useful as box plot

But the best one is pie chart giving easy visual comparison for various grades A, B,C,D,E and F

What are the solutions 2x^2 +7x=4

elena55 [62]

So your equation is $2x^{2} +7x = 4$ . You need to simplify this answer.
So first off, do 2x times 2x.
2 x 2 = 4.
Your equation is now $4x + 7x = 4.$
You're already off to a great start, so now let's add 4x + 7x. It is 11x.
Your equation is almost done! It's $11x = 4$ right now.
Divide both sides by 11, and your answer is...
0.36363636 and so on, or you can round to the nearest hundreth, in which it will be

0.36.

I hope I helped!
