Answer:
The system of equations is inconsistent because there's no solution.
Step-by-step explanation:
7y = 11.2x + 28 is a multiple of y = 1.6x + 4. Thus we have the same equation at the end.
Multiply y = 1.6x + 4 by 7.
7y = 11.2x + 28... Equation 1
7y = 11.2x + 28... Equation 2
Subtract equation 2 from 1.
7y - 7y = 11.2x - 11.2x + 28 - 28
0 = 0 + 0. There's no solution for x and y.
Probability of getting heads: 1/2
Probability of getting tails: 1/2
1/2 x 1/2 x 1/2 = 1/8
Answer:
x = 12/7
Step-by-step explanation:
You put: What you should have had is:
13x - 3y = 12 13x - 3y = 12
- x + 3y = 12 + x + 3y = 12
Now that we have that, we can do
14x = 24
Than, divide 24 by 14
x = 24/14
which we can simplify by dividing both by 2
x = 12/7
We can't simplify it down anymore, so this is our answer.
Answer:
-1/2
Step-by-step explanation:
slope=rise/run
rise is up or down
run is right or left
5/-10= -0.5= -1/2 or -5/10= -0.5= -1/2
the answer is -1/2
The probability of the Bob arrived before 1.30 P.M is 1/2 if the Alice arrives after Bob.
According to the question,
Alice and Bob each arrive at a party at a random time between 1.00 P.M and 2.00 P.M.
In probability theory, the sample space(s) of a random trial is the set all possible results of that trial.
Let 'x' be the arrival time of Alice and 'y' be the arrival time of Bob.
s = {(x, y) /1≤x≤2 and 1≤y≤2}
In order to find the probability of the Bob arrived before 1.30 P.M, if the Alice arrives after Bob.
Formula for Probability =
= 1/2
Hence, the probability of the Bob arrived before 1.30 P.M is 1/2 if the Alice arrives after Bob.
