Answer:
y=-2x-20
Step-by-step explanation:
y=mx+b
m=(y2-y1)/(x2-x1)
m=(-5+4)/(-6+8)
m=-1/2
y=-1/2x+b
-4=-1/2(-8)+b
-4=4+b
-8=b
y=-1/2x-8

Answer:
0.335
Step-by-step explanation:
1. There is a 30 percent chance of a flight being delayed because of icy weather ,then the probability of being delayed is 0.3 and of being not delayed is 0.7.
2. If a flight is delayed because of icy weather, there is a 10 percent chance the flight will also be delayed because of a mechanical problem, then the probability of being delayed is 0.1 and the probabilty of not being delayed is 0.9.
3. If a flight is not delayed because of icy weather, there is a 5 percent chance that it will be delayed because of a mechanical problem (MP), then the probability of being delayed is 0.05 and the probabilty of not being delayed is 0.95. (See attached probability tree)
Delayed of icy weather - 0.3
Delayed of MP when weather is not icy - 0.7·0.05=0.035
Now, if one flight is selected at random from the airport in January, the probability that the flight selected will have at least one of the two types of delays is
0.3+0.035=0.335

We assume that we are asked of the monthly contribution made by Melanie to a ROTH IRA. The give data are below:
Period = 34 years * 12 months = 408 months
Total contributions = $3,750
Solving for the monthly contribution, we have the solution below:
Monthly Contribution = Total contribution / period
Monthly contribution = $3750 / 408
Monthly contribution = $9.2
The answer is $9.2 monthly contribution.

Answer:
(2, 3 )
Step-by-step explanation:
The solution to a system of equations given graphically is at the point of intersection of the 2 lines.
point of intersection = (2, 3 ) ← is the solution
