Answer:
median of seventh grade = 16.5
median of ninth grade = 16.5
Step-by-step explanation:
median = middle number, there are 18 numbers in total of each set. Since its even the middle number is kinda 16 and 17, but you can only choose one so the middle of 16 and 17 is 16.5
Answer: 860
Step-by-step explanation:
there isn't a 860 for an answer but it's the correct answer.
Answer:
Step-by-step explanation:
10- -2 which gives you 12 cause the negatives make a positive.
-9 -0= -9
12 over -9 which simplifies to 4 over -3
C. 26.14
you just have to subtract rope B from rope A and you’ll get your answer :)
Step-by-step explanation:
Claim:
it takes n - 1 number of breaks to break the bar into n separate squares for all integers n.
Basic case -> n = 1
The bar is already completely broken into pieces.
Case -> n ≥ 2
Assuming that assertion is true for all rectangular bars with fewer than n squares. Break the bar into two pieces of size k and n - k where 1 ≤ k < n
The bar with k squares requires k − 1 breaks and the bar with n − k squares
requires n − k − 1 breaks.
So the original bar requires 1 + (k−1) + (n−k−1) breaks.
simplifying yields,
1 + k − 1 + n − k − 1
1 - 1 + n - 1
n - 1
Therefore, we proved as we claimed that it takes n - 1 breaks to break the bar into n separate squares.
