Answer:
see explanation
Step-by-step explanation:
(a)
Substitute x = - 1 into f(x)
f(- 1) = 6 - 2(- 1) = 6 + 2 = 8
(b)
Substitute x = into g(x)
g( ) = = 9 × 3 = 27
(c)
Substitute x = f(x) into h(x)
h(6 - 2x)
= 6 + (6 - 2x)² ← expand using FOIL
= 6 + 36 - 24x + 4x² ← collect like terms
= 4x² - 24x + 42
(d)
Substitute x = f(x) into g(x)
g(6 - 2x)
=
(e)
Evaluate g(12) then substitute value obtained into f(x)
g(12) = = , then
f( ) = 6 - (2 × ) = 6 - =
(f)
Evaluate f(- 9) then substitute the value obtained into h(x)
f(- 9) = 6 - 2(- 9) = 6 + 18 = 24 , then
h(24) = 6 + 24² = 6 + 576 = 582
-225=x-737
x=512
Answer: Suzy’s starting elevation was 512 ft above sea level
Mean Shift 1 = (18+25+56+42+29+38+54+47+35+30) / 10
Mean Shift 1 = (364) / 10
Mean Shift 1 =36.4
Absolute value (Mean Shift 1 - Population Mean)
Absolute value (36.4-42)
Absolute value (-5.6) = 5.6
Mean Shift 2 = (23+19+50+49+67+34+30+59+40+33) / 10
Mean Shift 2 = (404) / 10
Mean Shift 2 =40.4
Absolute value (Mean Shift 2 - Population Mean)
Absolute value (40.4-42)
Absolute value (-1.6) = 1.6
Mean Shift 3 = (19+22+24+40+45+29+33+29+39+59) / 10
Mean Shift 3 = (339) / 10
Mean Shift 3 =33.9
Absolute value (Mean Shift 3 - Population Mean)
Absolute value (33.9-42)
Absolute value (-8.1) = 8.1
Mean Shift 4 = (21+23+25+40+35+19+70+40+22+23) / 10
Mean Shift 4 = (318) / 10
Mean Shift 4 =31.8
Absolute value (Mean Shift 4 - Population Mean)
Absolute value (31.8-42)
Absolute value (-10.2) = 10.6
