Answer:

they are not inverses

Step-by-step explanation:

f(1) = 1/1 +3 = 1 +3 = 4

g(4) = 4/4 +2 = 1 +2 = 3 ≠ 1

If the functions were inverses, we would have g(f(1)) = 1, which we do not.

The given functions are not inverses.

The same would be true if your functions were

f(x) = 1/(x+3) and g(x) = 4/(x+2)

f(1) = 1/(1+3) = 1/4

g(1/4) = 4/(1/4 +2) = 4/(9/4) = 16/9 ≠ 1

20. Give an example of a controlled experiment and an observational study.

Kryger [21]

Answer:

We do studies to gather information and draw conclusions. The type of conclusion we draw depends on the study method used:

In an observational study, we measure or survey members of a sample without trying to affect them.

In a controlled experiment, we assign people or things to groups and apply some treatment to one of the groups, while the other group does not receive the treatment.

What is the value of g? 25(g−7)=3 Enter your answer in the box

Ratling [72]

First open the bracket by multiplying with 25

25g -25×7 =3

25g -175 =3

Add 175 to both sides

25g -175+175= 3+175

25g = 178

g = 178/25 is the value.

Answer:

1. $\dfrac{120}{285}=\dfrac{8}{19}$

2. $\dfrac{25}{285}=\dfrac{5}{57}$

Step-by-step explanation:

1. Russell is 5'9'' (under 6 feet). There are 130+120+35=285 players with the height under 6 feet and 120 of them are forwards. The probability that Russell is a forward is

$\dfrac{120}{285}=\dfrac{8}{19}$

2. Peter is 6'2'' (over 6 feet). There are 25+30+30=85 players with the height over 6 feet and 25 of them are guards. The probability that Peter is a guard is

$\dfrac{25}{285}=\dfrac{5}{57}$
