First change the mixed fraction into a improper fraction
8 5/6= 53
53/6 is your improper fraction
then flip it (reciprocal)
6/53 is your answer
hope this helps
Answer:
5 inches wider
Step-by-step explanation:
The given area expression factors as ...
x² +2x -15 = (x -3)(x +5)
Apparently, we're to assume that these factors represent length times width, and the factor x-3 corresponds to a length that is 3 inches shorter than the old length (x). Then the width is (x+5), which is 5 inches wider than the old length.
Answer:
Average grade for this test = 1.85
Step-by-step explanation:
Given that number of students receiving respective grade scores are : 11, 18, 52, 13, 6
Then total number of students = 11 + 18 + 52 + 13 + 6 = 100
Sum score obtained by total students
= 11F + 18D + 52C + 13B + 6A
= 11(0) + 18(1) + 52(2) + 13(3) + 6(4)
= 0 + 18 + 104 + 39 + 24
= 185
Now average grade for this test is given by 185/100 = 1.85
Hence final answer is 1.85.

Answer:
The results are
Face Count Face Count
1 6 4 9
2 12 5 5
3 8 6 20
These results are not fair, because they clearly shows that the dice was tricked. We deduct this by observing that he obtained the face 6, 20 times out of 48, which represents 42% of chances to get that result.
Now, a fair dice must have equal probabilities per side, or an approximation to that at least. In this case, we don't have such equality.
So, next time your little brother roll the dice, we probably will get 6.
