Step-by-step explanation:
Use the midpoint formula to find the midpoint of the line segment.
Midpoint formula is a mathematically equation used to measure the halfway point between two data points.
Calculating the midpoint is the same thing as calculating the average of two numbers. Therefore, you can calculate the midpoint between any two numbers by adding them together and dividing by two. For example, suppose you want to find the midpoint between the numbers 2 and 32. First, add the two numbers: 2 + 32 = 34.
I think don't get mad if its wrong :)

Answer:
a) No, since 80 is less than 2.5 standard deviations above the mean; b) Yes, since 80 is more than 2.5 standard deviations above the mean.
Step-by-step explanation:
For part a,
The mean is 70 and the standard deviation is 5. This means that 2 standard deviations above the mean is 70+5+5 = 80.
This means that 80 is not an outlier, as it is not more than 2.5 standard deviations above the mean.
For part b,
The mean is 70 and the standard deviation is 3. This means that 2 standard deviations above the mean is 70+3+3 = 76; 3 standard deviations above the mean is 70+3+3+3 = 79. 80 is more than this, so yes, it is an outlier.
Slope intercept form is the following: y=mx+b, m = slope, and b = y-intercept. Following this, the equation of the line should be: y = -2x + -3 Hope this helps :)
