Step-by-step explanation:
To calculate a slope, we need to apply: 
Applying formula to each slope:
So, as you can see, there are equal pair of slopes, meaning that they are parallels, which<em> demonstrate that it's actually a quadrilateral figure.</em>
Answer:
6m + n + 2
Step-by-step explanation:
[7m + 3n - 11 - 2m] + [n + 5 - -m - 3n + 8]
[5m + 3n - 11] + [n + 5 + m - 3n + 8]
5m + 3n - 11 + (-2n + 13 + m)
5m + 3n - 11 - 2n + 13 + m
6m + n + 2
Answer: x < - 8.5
Step-by-step explanation:
-46 - 8X > 22
+46. +46
-8x > 68
x < - 8.5
Answer: point estimate = 3.88
Margin of error = 0.63
Step-by-step explanation:
Confidence interval is written in the form,
(Point estimate - margin of error, Point estimate + margin of error)
The sample mean, x is the point estimate for the population mean. Let m represent the margin of error. Since the confidence interval is given as (3.25 , 4.51), it means that
x - m = 3.25
x + m = 4.51
Adding both equations, it becomes
2x = 7.76
x = 7.76/2
x = 3.88
Substituting x = 3.88 into x + m = 4.51, it becomes
3.88 + m = 4.51
m = 4.51 - 3.88
m = 0.63
