A cable provider wants to contact customers in a particular telephone exchange to see how satisfied they are with the new digital tv service the company has provided. all numbers are in the 174 exchange, so there are 10 comma 000 possible numbers from 174-0000 to 174-9999. if they select the numbers with equal probability: what is the probability the number selected will be an even number?

g(x) is the negative form of f(x)? because whenever its the negative form it reflects its self over the x axis. idk if this is right though.

step-by-step explanation:

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !

seems like it's already there

step-by-step explanation:

x can be -1 and 1 if it's absolute value is just one, so i think you're good.
