Answer:
Mean
Step-by-step explanation:
mean is the average of numbers put together and divided by the total amount of numbers, when finding the average annual income using the mean would be most effective

- Solving systems of equations graphically
Step-by-step explanation:
In order for a systems of equations to have a solution set, the 2 graphs must intersect at at least 1 point. Here, we see that graphs 1 and 5 do not intersect each other at all.
Therefore, the rest of the graphs have solutions and #1 and #5 do no have any solutions.
Answer:
The answer to your question is r = 44 mi/h
Step-by-step explanation:
Data
distance = d = 22 mi
speed = r = ?
time = t = 30 min
Formula
speed = distance / time or r = d/t
Process
1.- Convert minutes to hours
60 min ----------------------- 1 h
30 min ----------------------- x
x = (30 x 1) / 60
x = 30 / 60
x = 0.5 h
2.- Calculate the speed of the bus
speed = 22 mi / 0.5 h
speed = 44 mi/h
r = 44 mi/h
Substitute 4 for y. Then -3x^2 + 16 = 52.
Solve for x. Subtract 16 from both sides, obtaining -3x^2 = 36.
Divide both sides by -3, obtaining x^2 = -12. This last result makes no sense, as no square of a real number could be negative. Probably this is where you're ":getting a negative answer."
If imaginary answers were allowed, then x = i*√12 = i*2√3 or x = -i*2√3.
x =
