Step-by-step explanation:
Solve this system of equations by graphing. First graph the equations, and then type the solution. y=2x+2 y=x–2
Solution:
The equation of a straight line is in the form y = mx + b, where m is the slope of the graph and b is the y intercept (value of y when x = 0). To graph the line, online geogebra graphing calculator was used for plotting the two graphs by writing the equation of the graphs.
After plotting the two graphs, the intersection of the two lines should be traced to get the x coordinate and y coordinate of the point. This point is the solution of the two graph equations, hence:
The solution = (-4, -6)

Answer:
0.619
Step-by-step explanation:
from the question we have the following data:
probability of motor 1 breaking = 65% = 0.65
probability of motor 2 breaking = 35% = 0.35
probability of motor 3 breaking = 5% = 0.05
since we have 3 motors the probability of any of them breaking down is =
but what the question requires from us is the conditional probability of the first one being installed
we have to solve this questions using bayes theorem
such that:
=
=
= 0.618966
approximately 0.619
therefore the conditional probability ralph installed the first motor is 0.619
