Information that is collected for the first time from original sources is called primary research.
Primary research is research you contact yourself. A few examples of ways to collect primary research are through surveys, focus groups and observations.
Secondary research is information collected from other sources that once was primary research. Although they are complete opposite to get the most accurate research data it is best to use both primary research and secondary research in your market research.
They both could be working together to find out how and when the truck driver would have fallen asleep and what could have caused him to fall asleep. Next, they could both figure out if the ammonia was in sealed containers and if not why. You could even come to the conclusion of the ammonia could have leaked from the containers and exposed the driver putting him to sleep.
Answer:
16.25;
g(f(x)) ;
76 ;
f(g(x))
Explanation:
For 15 off
f(x) = x - 15
For 35% off
g(x) = (1 - 0.35)x = 0.65x
g(x) = 0.65x
A.)
For the $15 off coupon :
f(x) = x - 15
f(x) 40 - 15 = 25
For the 35% coupon :
g(x) = (1-0.35)x
g(x) = 0.65(25)
g(x) = 16.25
B.)
Applying $15 off first, then 35%
Here, g is a function of f(x)
g(f(x))
Here g(x) takes in the result of f(x) ;
For the $140 off coupon :
f(x) = x - 15
f(140) = 140 - 15 = 125
For the 35% coupon :
g(125) = (1-0.35)x
g(124) = 0.65(125) = $81.25
C.)
x = 140
g(x) = 0.65x
g(140) = 0.65(140)
g(140) = 91
f(x) = x - 15
f(91) = 91 - 15
f(91) = 76
D.)
Here, F is a function of g(x)
f(g(x))
f(x) = (0.65*140) - 15
