The empirical rule states that approximately 68/95/99.7% of a normal distribution lies within 1/2/3 standard deviations. So the answer is 68%.
Answer:
- No, there is no proportional relationship
Step-by-step explanation:
<u>The proportional relationship is:</u>
- y = kx, which is a special form of linear equation, with zero y-intercept
<u>In the given case we have:</u>
This is a linear function but not proportional relationship because it has y-intercept, different than zero
Yesssssssssssssssss 2:1 is basically 2:1 can be converted into 2 wholes and 14:6 can also be converted into 2 wholes.
Answer: choice C) 3
--------------------------------------------------
Explanation:
Using any two points, we can find the slope through the slope formula. In this case, I'm using the first two points (from the first two rows)
m = (y2 - y1)/(x2 - x1)
m = (1-(-2))/(-1-(-2))
m = (1+2)/(-1+2)
m = 3/1
m = 3
The slope is 3 meaning that each time x increases by 1, y increases by 3.
