Answer:
Substitute the slope and the coordinates of point P in the equation of the line y=mx+b and then solve for b in each equation
Step-by-step explanation:
we know that
The first step is calculate the slopes of these two lines. Remember that if two lines are parallel then the slopes are the same (m1=m2) and if two lines are perpendicular then the slopes is equal to m1*m2=-1
The second step is substitute the slope m2 and the coordinates of point P in the equation of the line in slope-intercept form y=mx+b and then solve for b in each equation
I think it is going to be 3. please let me know if you need more information
Answer:
Probability of winning on one try : 1.16060875e-8
Step-by-step explanation:
For the first first 4 numbers.
Probability is 1/46 for the first number. Since the numbers are different, and it doesnt matter the order, the second number has a probability now of 1/45, the third has a probability of 1/44 and the last one a probability of 1/43.
Since the probability is dependan of the results of hitting the other number the probability of the first for numbers is the multiple of the 4 probabilities.
So it is 1/46 * 1/45 * 1/44 * 1/43 = 1 / 3916440
And that number is then multiplied by the probabilty of hitting the last number. 1/22
So the final probability is :
1/86161680 = 1.16060875e-8
