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
The ratio adults to students is 1:6
Multiply both sides by 60 so that the right side is 360 and it is
60:360
Therefore there needs to be 60 adults which is option D
Hope this helps :)
No, because if you substitute x for 1 the left side is 7.2, the bottom is 8.2, and the right is 4.2
F(1) = 4; f(n+1) = f(n) - 1.25
f(1) = 4
f(2) = f(1) - 1.25 = 4 - 1.25 = 2.75
f(3) = f(2) - 1.25 = 2.75 - 1.25 = 1.50
f(4) = 1.50 - 1.25 = 0.25
f(5) = 0.25 - 1.25 = -1
f(6) = -1 -1.25 = -2.25
Sequence: 4, 2.75, 1.50, 0.25, -1, -2.25, ...
