Ishaan to have a score of 97 on the next exam have an overall average of 85
What is the mean of exam scores?
The mean of exam scores is the sum of the scores divided by the number of exams taken, more like an average of all scores
Initially, average score on 4 exams is 82
average=total score/number of exams
average score on 4 exams=82
total score =unknown=assume it is
number of exams=4
82=x/4
x=4*82
x=328
In order to have an overall average score of 85, we would sum the total score of 4 exams and the fifth exam and divide by 5 exams
85=(328+y)/5
85*5=328+y
425=328+y
y=425-328
y=97

Answer:
b = d/(2ac)
Step-by-step explanation:
10abc - 2d = 3d
Add 2d to each side
10abc - 2d+2d = 3d+2d
10 abc = 5d
Divide each side by 10ac
10 abc/ (10ac) = 5d/10ac
b = d/(2ac)

Problem OneThis is one of those questions that you might think is silly until you try it for yourself or you read about it.
The thing you have to understand, which is not well stated, is that oblique cylinders have circles on the top and bottom. You guys (in the United States) still have pennies, don't you? Take 10 or twelve of them and make a stack where each penny sticks out 1/16 of an inch from the edge of the penny below it. I can't draw it I don't think (even my stick men look like someone who can't hold a pencil drew them), but maybe I can find a picture or you can.
Got it.
So the oblique cylinder has a circle on the top and bottom, just the way the pennies do when you stack them like the cylinder below. Then you can stack them like a soup can. Did anything change? No
The
correct answer is (drum roll please) <<<<<<< <em>They are the same volume.
</em>
Problem 2<em />Suppose you have a glass whose sides are straight up and down (a right cylinder with no top). You fill the glass with water. Stop a moment to consider this. Now magically you place a plain right through the middle of the glass.
Question: is there any difference between the shape of the plain at the top of the glass than that shape at the middle? (You should answer that they are the same shape -- a circle -- at both the top and middle of the glass).
If you caught on, you would have said that the shapes are the same in your question.
