Answer:

5.656 units

Step-by-step explanation:

Data provided:

coordinates of the point 1 as (−1,−13)

and,

coordinates of the point 2 as (3,−9)

Now,

The distance between the two points whose coordinates is given is calculated using the formula

distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

on substituting the respective values, we get

distance = \sqrt{(3-(-1))^2+(-9-(-13))^2}

or

distance = \sqrt{(4)^2+(4)^2}

or

distance = \sqrt{16+16}

or

distance = √32

or

distance = 5.656 units

What is the standard deviation of a normal distribution, whose mean is 35, in which an x-value of 23 has a z-score of -1.63?
Dvinal [7]

Answer:

7.36

Step-by-step explanation:

z-score is:

z = (x − μ) / σ

Given that z = -1.63, x = 23, and μ = 35:

-1.63 = (23 − 35) / σ

σ ≈ 7.36
