Answer:
Step-by-step explanation:
Given that there is a t distribution with 7 degrees of freedom.
P(-1.29 < t < 1.29)=1-0.2380
=0.7620
b) Now there is a different t distribution with 18 df.
When 
c=-1.733
Answer:
4x=90
X=90÷4
X=22.5
5x-27=90
5x=90+27
5x=117
X=117÷5
X=23.4
So 23.4 is a larger angle
It is; Five million Six hundred seventy four thousand eight hundred ninety. As simple as that.
