What is the ninth term in the binomial expansion of (x-2y)^13

Step-by-step explanation:

x is the first term in the given parenthesis and y is the second tern

r= 8, r+1=9 because we need to find 9th term

x is x and y is 2y. n is the exponent 13. plug in all the values

nCr=

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

c - they will have the same distribution
