Problem Statement
We are asked to find the critical t-value for a confidence level of 80% and sample size of 17.
Method
To solve this, we simply need to do two things:
1. Calculate the degrees of freedom:
Answer:
1.) 4
2.) -11
3.) -4
4. 19
Step-by-step explanation:
20)
using
<span>a^3 + b^3 = (a+b)(a^2 − ab + b^2)
</span>so
w^3 + 125z^3
= w^3 +(5z)^3
= (w + 5z)(w^2 - 5wz + 25z^2)
hope it helps
