Answer:
A, B and D are true statements.
Step-by-step explanation:
We are given a binomial expansion


Now we will check each option
Option A: The coefficients of
and
both equal 1.
If we see first and last term of the expansion, This statement is true.
Option B: For any term
in the expansion, a + b = n.
Let we take 3rd term of expansion
Here, a=n-2 and b=2
If we do a+b = n-2+2=n
a+b=n is true statement.
Option C: For any term x^ay^b in the expansion, a - b = n.
Let we take 3rd term of expansion
Here, a=n-2 and b=2
If we do a-b = n-2-2=n-4≠n
a-b=n is false statement.
Option D: The coefficients of x^ay^b and x^by^a are equal.
If we take second term from beginning and last of the expansion.


This statement true.
Answer:
Step-by-step explanation:
For Mia:
distance,d = 100 yard
time, t = 2 min 33 sec = 153 s
Speed = distance / time
speed = 100 / 153 = 0.65 yard/s
For Larisa:
distance, d = 350 yard
time, t = 5 min 18 sec = 318 s
speed = 350 / 318 = 1.1 yard/s
So, the speed of Larisa is more than the speed of Mia.
Answer: the last second one: 3/4 0.8 94%
Step-by-step explanation:
because 3/4 is smaller than one so it has to go first.
