Answer: 11
Step-by-step explanation:
We know that the degree of freedom for a t-distribution is given by :-
, where n is the sample size.
Given : A repeated-measures experiment and a matched-subjects experiment each produce a t statistic with df = 10.
Then, the number of individuals participated in each study =
Hence, the number of individuals participated in each study =11.
a and c both have √x , so they will both be in brackets multiplied by √x.
b is the only term with √y so it will be outside of the brackets.
So the answer will be:
(a - c)√x + b√y
We can check this by expanding the brackets:
(a - c)√x + b√y
= a√x - c√x + b√y
We can rearrange this to get the same original expression:
a√x - c√x + b√y
= a√x + b√y - c√x

Answer:
Last option: (a - c)√x + b√y
Answer:
B
Step-by-step explanation:
Use the pythagorean theorem
a² + b² = c²
a² + 63² = 65²
a² + 3969 = 4225
a² = 256
a = 16
x = 16 meters
