A number is chosen at random from the first 100 positive integers. Find the probability that the number is divisible by 5. 1/10
rosijanka [135]
The number of multiples of 5 from 1 to 100 is:

1≤5n≤100

1/5≤n≤20, since n must be an integer

1≤n≤20

So the multiples of five number 20-1+1=20 elements, and the probability of choosing one of the multiples from the first 100 positive integers is:

P(5n)=20/100=1/5

Graph the line y+3=2(x+2)
Daniel [21]
Attached is the line graphed. But first to graph this line you must get y by itself. 

1.Multiply 2 to everything in the parentheses. You should get y+3=2x +4. 
2.Subtract 3 from both sides to isolate the y-variable.You should get y=2x+4-3
3.Simplify. You should get y=2x+1.
4.Pull out the slope and y-intercept and graph the line.
