the answer is easy.
Step-by-step explanation:
Answer: yes
Step-by-step explanation: slope is 4/3 and y intercept is 8
m= Y-20/0-9
4/3= y-20/-9
4/3 x -9 = y-20
-12 = y-20
Y=20-12
Y=8
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
