Step-by-step explanation:

the answer this can be solved by the function:

324 = 27x + 243

-243          -243

27x = 81

/27     /27

x = 3 hours past 7.

You are playing a board game with your little sister. Moves are determined by rolling 2 six-sided dice. The red die tells you th
enot [183]

Answer: The probability is 1/9.

Step-by-step explanation:

First, let's define the possible outcomes of each dice:

Red: Forward (4 times), Backward (2 times)

Green : {1, 1, 2, 2, 3, 4}

We want to find the probability of moving backward 2 spaces.

Then we need to find the probability of rolling a "backward" in the red dice, and a 2 in the green dice.

First, the probability of rolling a backward in the red dice is equal to the quotient between the number of outcomes that are "backward", and the total number of outcomes in the dice (there are 2 backwards and 6 outcomes in total), this is:

p1 = 2/6 = 1/3.

And the probability of rolling a 2 in the green dice is equal to the quotient between the number of outcomes with a 2, and the total number of outcomes. (The 2 appears two times, and there are 6 possible outcomes):

p2 = 2/6 = 1/3.

Now, the probability of both events happening at the same time is equal to the product of the individual probabilities, then the probability of moving backwards 2 spaces is:

P = p1*p2 = (1/3)*(1/3) = 1/9.

ss7ja [257]

Answer:

Mid point:

= ( \frac{3 +  - 5}{2} , \:  \frac{1 + 8}{2} ) \\  = ( - 1, \: 4.5)

distance:

=  \sqrt{ {( - 5 - 3)}^{2} +  {(1 - 8)}^{2}  }  \\  =  \sqrt{64 + 49}  \\  =  \sqrt{113}  \\  = 10.6 \: units

slope:

=  \frac{1 - 8}{ - 5 - 3}  \\  =  \frac{ - 7}{ - 8}  \\  =  \frac{7}{8}
