Answer:

The probability of rolling a 3 and then a 5 is 1/36.

Step-by-step explanation:

Rolling a six sided die is an independent event.  That means for each roll, you have the same chance of rolling a number as the previous roll.  Since there are six different numbers on a die, then there are six different outcomes for each roll - 1, 2, 3, 4, 5 or 6.  The chances that you would roll a '3' is 1 out of 6, or 1/6.  The chances that you would roll a '5' is also 1 out of 6, or 1/5.  However, when we combine these events, we need to take each probability and multiply them.  So, the probability of rolling a '3' and then a '5' is 1/6 x 1/6 or 1/36.

2 1/2r + 1 + 2r = 9 1/10
GalinKa [24]

This should help you here are the steps of your problem :)


2*(1/2)*r+2*r+1 = 9*(1/10) // - 9*(1/10)


2*(1/2)*r+2*r-(9*(1/10))+1 = 0


2*(1/2)*r+2*r-9/10+1 = 0


3*r+1/10 = 0 // - 1/10


3*r = -1/10 // : 3


r = -1/10/3


r = -1/30


r = -1/30


So your answer would be 1/30

What are the solutions to the system of equations? y=2x^2−6x+3 y=2x+3
adoni [48]

Answer:

Step-by-step explanation:

y=2x²-6x+3

y=2x+3

2x²-6x+3=2x+3

2x²-6x+3-2x-3=0

2x²-8x=0

2x(x-4)=0

x=0,4

y=0+3=3

and y=2(4)+3=11

so solutions are (0,3) and (4,11)
