How can we interpret standard deviation using the Empirical Rule?

1 answer:

3 0

Answer:The empirical rule notes that almost all of the data would fall within three standard deviations of the mean for a normal distribution. The empirical rule can be broken down into three parts: within the first standard deviation from the mean, 68 percent of data drop. Two standard deviations account for 95 percent.

Step-by-step explanation:

Given f(x) then f(x - 2) represents a horizontal translation of f(x) shifted 2 units to the right, thus

The marked points on f(x) → f(x - 2) are

(0, 0 ) → (2, 0 )

(2, 4 ) → (4, 4 )

(3, 9 ) → (5, 9 )

Four more than three times n equals -5

3n+4=-5

do the opposite of adding 4. this means you have to subtract 4 from 4. whatever you do to the problem, you must do to the answer. now subtract 4 from -5.

-5-4=-9

since 4-4=0, we can take 4 out of the equation. now you have:

3n=-9

now divide -9 by 3

-9/3=-3

n=-3

hope this helps :)
