Hello from MrBillDoesMath!
Answer:
- 8064 x^5 y^5
Discussion:
The binomial theorem gives us the expansion of (a + b) ^n :
(a + b ) ^n
= a^n + na^(n-1)b + (n(n-1)/ 2!) a^(n-2)b^2 +....
In our case, taking the 6th term above, setting a = 2x, b = -y, and n = 10 gives
( (10*9*8*7*6)/ (5 *4*3*2*1) ) * (2x)^5 (-y)^5r
= - 8064 x^5 y^5
Thank you,
MrB
Answer: 1.(-3.4)(5)=-17
2.(-8)(2.2)=17.6
3. (3.8)(-5)=-19
4.(-9.5)(-2)
Step-by-step explanation:
Given that n = 18, then the degree of freedom is n - 1 = 17.
From the table of Chi Square
The value of
to the left for 95% confidence interval given a degree of freedom of 17 is 8.672
Answer:
12
Step-by-step explanation:
since you already know that the short sides together are 4 inches, that means there's 18 inches left, so 9 inches for each long side. Add 3 to 9 and you have your unknown number.
The correct answer is 12. Hope this helps.
