Answer:
First term: -10
Fourth term: -55
Eighth term: -115
Step-by-step explanation:
I am assuming the means -5(3n-1). To find the first term, plug in 1. You will get -5(3*1-1) or -5*2 or -10.
To find the fourth term, plug in 4. You will get -5(3*4-1) or -5*11 or -55.
To find the eighth term, plug in 8. You will get -5(3*8-1) or -5*23 or -115.
So the answers are -10, -55, and -115.

Answer:
x=4
Step-by-step explanation:
1) first write it down --> 11x-2+9x+1=19x+3
2) then combine like terms on the left side of the equation. --> 20x-1=19x+3
3) Then subract 19x on both sides --> x-1=3
4) After add 1 to both sides --> x=4
Answer: No, this is not necessarily evidence that the proportion of Americans who are afraid to fly has increased.
Step-by-step explanation:
Since we have given that
n = 1400
x = 154
So, 
and p = 0.10
So, hypothesis would be

So, the test statistic value would be

At 5% level of significance,
critical value would be 1.96.
Since 1.96>1.25.
so, we will accept the null hypothesis.
Hence, no, this is not necessarily evidence that the proportion of Americans who are afraid to fly has increased.
