Answers:
1) (s o t)(x)=4x^2-x-4
2) (t o s)(x)=4(x-7)^2-(x-7)+3
Solution:
1) (s o t)(x)=s(t(x))=s(4x^2-x+3)=(4x^2-x+3)-7=4x^2-x+3-7
(s o t)(x)=4x^2-x-4
2) (t o s)(x)=t(s(x))=t(x-7)=4(x-7)^2-(x-7)+3
(t o s)(x)=4(x-7)^2-(x-7)+3
Look like that first one is supposed to have a denominator of 2.
This is a geometric series with a common ratio 4, so it diverges (absolute value 1 or more), meaning it has no sum. Choice C.
1. The mean is calculated using:
(9.4 + 17 + 7.3 + 7 + 16.1 + 5.4 + 5.9 + 8.5 + 4.2 + 9.2)/ 10
= 9
2. The standard deviation is 4.31
3. The years are 1996, 1997, 1999-200
