Answer:
The 98% confidence interval for the mean number of hours of study time per week for all students is (20.9, 25.1).
Step-by-step explanation:
Confidence interval:
Sample mean plus/minus the margin of error.
In this question:
Mean of 23.
Margin of error 2.1.
Then
23 - 2.1 = 20.9
23 + 2.1 = 25.1
The 98% confidence interval for the mean number of hours of study time per week for all students is (20.9, 25.1).
Turn them into percentages:
2/6=1/3=33.333%
5/12=42%
3/7=43%
4/10=2/5=40%
Now put them in order :)
2/6,4/10,5/12,3/7

Answer:
4) y+2 = 3(x+1)
5) y+2 = -1(x-1)
6) y+3 = 0(x-2) OR y=3
Step-by-step explanation:
M is given and is the slope
X and Y change signs (positive becomes negative and vice versa)
