i don't really understand this problem
Answers
Answer:
Step-by-step explanation:
So what you need to do is mark to points on the graph. For example (9,4) and (18,8). The run would be 9 and the rise would be 4. Gradient = rise/run which is 4/9. So that's the gradient. Now it asks for the equation. The formula for an equation is y=mx+c m= the gradient and c = the y-intercept (the y intercept is where the line meets the axis so it would be 0) so the answer is: y=4/9x+0.

Answers
Answer:
1. 68%
2. 95%
3. 99.7
Step-by-step explanation:
Standard deviation of mean will be 68%, 95%, and 99.73% respectively.
What is Empirical Rule?A statistical rule known as the empirical rule, which is also known as the three-sigma rule or the 68-95-99.7 rule, states that almost all observed data for a normal distribution will be within three standard deviations of the mean or average.
Given according to the empirical rule, 68% of observations will fall within the first standard deviation (µ ± σ), 95% will fall within the first two standard deviations (µ ± 2σ), and 99.7% will fall within the first three standard deviations(µ ± 3σ) .
Hence SD of mean will be 68%, 95%, and 99.73%
