Answer:

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

If the crate took 8 seconds to go from traveling at 2 meters per second one way to moving at 2 meters per second in the opposite
Angelina_Jolie [31]

Answer:

-0.5 ms^-2

Step-by-step explanation:

The initial velocity (u) = 2 ms-1

Final velocity (v) = 2 ms-1

Time taken (t) = 8 seconds

However the question clearly says that the final velocity is in opposite direction to the initial velocity. This implies that we have (-v), final velocity in opposite direction.

We must recall that vectors in opposite direction are commonly shown using a negative sign. Velocity is a vector, hence it possesses both magnitude and direction as we can see from the question.

Hence;

From a= v-u/t

a= (-2) - 2 / 8 = -0.5 ms^-2

Hence the acceleration of the crate is -0.5 ms^-2

At a bakery, a baker prepares 6 dozen blueberry muffins for every 5 dozen apple muffins. If the baker prepares 16 dozen blueberr
spayn [35]
I would write a proportion, I can't use a fraction bar so they will just be on top of each other:
Blueberry Muffins    6
Apple Muffins          5
For every 6 Blueberry muffins there are 5 apple muffins (dozens)
So when he makes 16 blueberry muffins (dozens)
You write it next to the '6' because it's talking about blueberry muffin dozens.
The proportion now:

Blueberry Muffins  6   16
Apple Muffins        5    x
To find x, or the number of apple muffin dozens, you multiply 16 * 5, which is
80.
Then divide by 6.
80/6= 13.333
You can't have .333 of a dozen, so round it to 13.
***ANSWER*** 
He prepared 13 Apple muffin dozens.
