Answer:
b= 7 - (3a/4)
Step-by-step explanation:
Assuming you don't know what "a" equals:
-subtract 3a/4 from both sides
b= 7 - (3a/4)
- The system of equations has infinite many solutions.
- The y-intercepts of the equations are -8
- The slope for the Rover A equation is 1.9 and slope for the Rover B equation is 1.9
Step-by-step explanation:
Given equations are:
Rover A: y= 1.9x – 8
Rover B: 7y= 13.3x - 56
simplifying the second equation
Dividing both sides by 7
As we can see that both equations are equivalent
Slope-intercept form is :
Comparing both equations with slope-intercept form we get
Slope of Rover A = 1.9
Slope of Rover B = 1.9
y-intercepts = -8
As both equations are equivalent, the system will have infinite many solutions.
Hence,
- The slope for the Rover A equation is 1.9 and slope for the Rover B equation is 1.9
- The y-intercepts of the equations are -8
- The system of equations has infinite many solutions.

Answer:
B) 5√3
Step-by-step explanation:
Answer:
1) 0.338
2) 0.4065
3) 0.2555
Step-by-step explanation:
1. The probability that they will lose both contracts is the probability of losing contract 1 and 2 altogether:
The probability of losing contract 1 is: 1 - 0.35 = 0.65
The probability of losing contract 2, given that they lose contract 1 is: 1 - 0.48 = 0.52
The probability of losing both contracts is 0.65*0.52 = 0.338
2. The probability that they win only one contract is the probability they they win contract 1, lose contract 2, plus the probability that they lose contract 2, win contract 1:
0.35*(1-0.73) + (1-0.35)*0.48 = 0.0945 + 0.312 = 0.4065
3. The probability that they win both contract is
0.35 * 0.73 = 0.2555
