Answer:
The scores within one standard deviation of the mean are: 77, 79, 80, 83, 87, 88
Step-by-step explanation:
The mean of the data is 83 and the standard deviation is 6.5, find scores within 1 standard deviation of the mean:
Between
83 - 6.5 = 76.5
83 + 6.5 = 89.5
So:
The scores within one standard deviation of the mean are: 77, 79, 80, 83, 87, 88
This is the simplest way I could explain that complex question.
Answer:
The error is founded in the slope, specifically in the run.
When seen a negative slope, that only applies to the rise but <u>not</u> the run.
Instead, the student should run 1(not 2) units to the <u>right</u>.
The slope had not mentioned any 2 in the run.
So it would sound like down 3, over 1, starting from 2.
5x + 8000 = 3x + 10000
x = 1000
