If you roll two four-sided dice (numbered 1, 2, 3, and 4), what is the probability that the sum of the dice is 3?
Elan Coil [88]

Answer:

The probability that the sum of the dice is 3, is 3/16.

Step-by-step explanation:

It is given that two four-sided dice are rolled.

Total number of sides of each dice = 4

Possible values for each dice = 1,2,3,4

If two four-sided dice are rolled, then the total possible outcomes are

A=\{(1,1),(1,2),(1,3),(1,4),(2,1),(2,2),(2,3),(2,4),\\(3,1),(3,2),(3,3),(3,4),(4,1),(4,2),(4,3),(4,4)\}

Total number of possible outcomes = 16

The sum of the dice is 3.

\text{Favorable outcomes}=\{(1,1),(1,2),(2,1)\}

Total number of favorable outcomes = 3

The probability that the sum of the dice is 3.

Probabilty=\frac{3}{16}

Therefore the probability that the sum of the dice is 3, is 3/16.

Point A is at (3, 4) and point M is at (1, 0). Point M is the midpoint of segment AB. What
kompoz [17]

Answer:

B (-1 , -4)

Step-by-step explanation:

A (3 , 4)  

M (1 , 0)

B\left( x_{B},y_{B}\right)

M is the midpoint of segment AB means :

\begin{cases}\frac{x_{A}+x_{B}}{2} =x_{M}&\\ \frac{y_{A}+y_{B}}{2} =y_{M}}{} &\end{cases}

Then

\begin{cases}x_{B}=2x_{M}-x_{A}&\\ y_{B}=2y_{M}-y_{A}&\end{cases}

Then

\begin{cases}x_{B}=2\left( 1\right)  -3&\\ y_{B}=2(0)-4&\end{cases}

Then

\begin{cases}x_{B}=-1&\\ y_{B}=-4&\end{cases}

How do I solve this ?
erica [24]
4x+3y=10
You want to isolate the y so subtract 4x from each side

3y=-4x+10
You want to isolate the y so divide everything by 3

y=-(4/3)x+(10/3)
That’s what y is
