This lesson asked you to investigate what it means for data to fall within 1, 2, and 3 standard deviations from the mean in a va
s2008m [1.1K]

Answer:

The data in statistics is generally supposed to deviate or vary from the mean. Standard deviations of 1, 2, and 3 are commonly used to calculate variability according to the empirical norm. In a normal distribution, we estimate 68 percent, 95 percent, and 98 percent of the data to be within 1, 2, and 3 standard deviations of the mean, respectively. This implies that the given percentage of data will lie within an interval of less than or greater than the standard deviation. If the values within a given standard deviation from the mean are standardized, the z value will always be equal to or less than the given standard deviation.

We should look at a program that aims to help people get out of poverty by using the standard deviation principle. The aim of the program is to provide free seeds to poor people who have been suffering from low yields due to the use of local seeds. If we use the definition of one standard deviation of the mean, or 2 and 3, we will favor the majority of people, but we will leave the poorest people in society behind.

Scientific notation<br> 9 * 10^12 ÷ 4.5 × 10^12
labwork [276]

Answer:

2*10 ^0 = 2

Step-by-step explanation:

9 * 10^12 ÷ 4.5 × 10^12

Divide the numbers

9/4.5

=2

Divide the exponents by subtracting

10^12 ÷  10^12 = 10 ^(12-12) = 10^0

Put them back together

2 * 10 ^0

Fill in the blank and dropdown menus to form a true statement below.​
Pavlova-9 [17]

Answer:

It's polyhedron, not polygon

Because above figure has merely 10 sides.

so the polyhedron above has 10 sides, each of them has 20°.

so total degree in polyhedron is > 180(n-2)

>180(10-2)

> 180×8

> 1440

Step-by-step explanation:

Hope it helps you

Find the length of the missing side. Leave your answer in simplest radical form.
Hatshy [7]

Answer:

The SQ Root of 493

Step-by-step explanation:

Becaues this triangle is a right triangle, we can find the missing side usiing the pythagorean theorum.

The pythagorean theorun states A^2 + B^2 = C^2, so 18^2 + 13^2= 439

Then all you have to do is find the sq root of 439, but this question askes you not to.

Hope this helps :)

Solve for x:<br> 9x - 3 - 8x = 7 - x<br> x= -7<br> x=-2<br> x = 4<br> x = 5
ruslelena [56]

Answer:

x = 5

Step-by-step explanation:

Given

9x - 3 - 8x = 7 - x , that is

x - 3 = 7 - x ( add x to both sides )

2x - 3 = 7 ( add 3 to both sides )

2x = 10 ( divide both sides by 2 )

x = 5
