The answer is <span>D. ax4y6
proof
the binome of newton is S a x^k y^n-k = (x+y)^n, for k=0...n
for n=10, it is </span>a y^10+...+ <span>a x4 y^10-4 +...+ax^10</span>

The answer is in the pictures.
D : 38 (Multiply 3 by 11 to cancel out the 3 then add 5 to cancel out the 5)
Based on the relative frequency and the number of times the experiment is to be performed, the number of times Event A should occur is 10 times.
<h3>How many times should Event A occur?</h3>
The relative frequency in this regard is 1/3.
The number of times it will occur can be found as:
= Relative frequency x Number of times event was performed
Solving gives:
= 1/ 3 x 30
= 10 times

Answer: Hence, the value of 
is 1.
Step-by-step explanation:
Since we have given that
ABC is a right angled triangle.
We need to find the value of 
As we know the formula for "Cosine Rule ":
similarly,
So, 
Hence, the value is 1.
