Answer:
A. The mean will increase.
Step-by-step explanation:
The mean is the average of the numbers. You just add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
84 + 75 + 76 + 80 + 48 + 75 = 438
438 / 6 = 73
mean = 73
The outlier is 48, so when you remove it, there will now be only five numbers in the set, and the mean will increase in size.
84 + 75 + 76 + 80 + 75 = 390
390 / 5 = 78
NEW mean (without the outlier) : 78
Angle ECD is 118°, let me know if you need an explanation or just wanted the answer
Answer:
y = -3.5x + 15
Step-by-step explanation:
Your slope-intercept equation is always y = mx + b
Using this formula, we need to find slope first: m = (y2-y1) / (x2-x1)
Step 1: Find slope
m = (1-8) / (4-2)
m = -7/2
Step 2: Plug in into slope-intercept form
y = -3.5x + b
Step 3: Find <em>b </em>(Plug in a coordinate given)
1 = -3.5(4) + b
1 = -14 + b
b = 15
Step 4: Combine it all together
y = -3.5x + 15
And you have your final answer.
