Answer:y=2x+10
Cost is 22.00
Step-by-step explanation:
B=10 m=2
C=2(6)+10
C=12+10
C=22.00
Answer:
Infinitely many
Step-by-step explanation:
2x + 2y = 8
x + y = 4
4x + 4y = 16
x + y = 4
Basically they represent the same line.
So all points on the line will satisfy both equations.
Hence infinitely many solutions
Answer:
Point estimate is 16 and Margin of error is 9
Step-by-step explanation:
The point estimate is given by the following formula:
Point estimate = (Lower Bound + Upper Bound) / 2
Replacing we have:
Point estimate = (7 + 25) / 2 = 32/2
Point estimate = 16
Now, the margin of error is given by the following equation:
Margin of error = (Upper Bound - Lower Bound) / 2
Margin of error = (25 -7) / 2 = 18/2
Margin of error = 9
