For a normal distribution what percentage of data falls within one standard deviation of the mean

Mathematics

8 0

Answer:

For a normal distribution 68% of data falls within one standard deviation from mean on both sides of mean

Step-by-step explanation:

A normal distribution's graph is a bell shaped curve that is completely described by its mean and standard deviation. Standard deviation is measured in terms of distance from mean.

34% of data is covered in one standard deviation from mean on one side.

Therefore, for a normal distribution 68% of data falls within one standard deviation from mean on both sides of mean ..

Step-by-step explanation:

Firstly, notice that this shape is composed of ³/₄ of a circle and ¹/₂ of a square;

The lower left part is the ¹/₂ square, with only 2 sides (a left and lower side) of length 3 units;

The perimeter of this part of the shape is simply the sum of the two sides:

3 + 3 = 6

The remaining part is the ³/₄ circle, which has a radius of 3 units;

The circumference of a circle is found by the formula:

πd

d = diameter = 2 × radius

We only have ³/₄ of the circle, however, so we only have ³/₄ the circumference:

³/₄ × π(2(3)) = ³/₄ × 6π

= ⁹/₂π (or, equally, 4.5π)

So the total perimeter is the sum of the perimeter of the ¹/₂ square and the ³/₄ circle:

4.5π + 6

Which shows the length of the darkened arc? (The wierd symbol next to the answers is Pi)​
fgiga [73]

Answer:

15 pi

Step-by-step explanation:

The circumference of the circle is given by

C = pi * d

C = pi *18

We are subtracting part of the circumference that covers 60 degrees

The entire circle is 360 degrees

60/360 = 1/6

We are subtracting 1/6 of the circumference

1/6 *18pi = 3pi

We have 18pi and subtract 3pi = 15pi

The dark shaded arc is 15pi

What is the distance between the pool in the main office in miles? Round to the nearest 10th period (8,1)(6,-6)
CaHeK987 [17]

Answer & Step-by-step explanation:

For this problem, we are going too have to use the distance formula.

Distance = \sqrt{(x2-x1)^2+(y2-y1)^2}

We can plug in the coordinate points that we are given to their respectful places.

Distance=\sqrt{(6-8)^2+(-6-1)^2}

Distance=\sqrt{(-2)^2+(-7)^2}

Distance=\sqrt{4+49}

Distance=\sqrt{53}

Distance=7.3

So, the distance between the pool and the main office is 7.3 miles.
