How can we interpret standard deviation using the Empirical Rule?

Mathematics
1 answer:
zalisa [80]3 years ago
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.

Answer:

see explanation

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
Verizon [17]
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 :)

2. What is the value of x if the angles<br> within a triangle are 2x +1, 7x-2 and 3x<br> +5?
noname [10]

Answer:

 x=14.67\\°

Step-by-step explanation:

The sum of all the three angles of any triangle is 180°

Putting sum of all the angles given equals to 180°

                      (2x+1)+(7x-2)+(3x+5)=180°

                              2x+7x+3x+1-2+5=180°

                                                         12x+4=180°

                                                                   x=\frac{180-4}{12}

                                                                   x=14.67\\°

The value of the x is found on solving the given angles of the triangles.
