Answer: Stratified sampling

Step-by-step explanation:

A random sampling where the population is divided into non-coinciding groups are called strata and a sample is picked out by some design within each strata is known as stratified sampling.

Given : The population of a town is divided into three age categories which are strata . A random sample of each category is surveyed about voting

choices.

Then this type of sampling is called stratified sampling.

Answer:

The population of a town is divided into three age categories. A random sample of each category is surveyed about voting choices. this type of sampling is called stratified sampling.

Using the Pythagorean Theorem, find the length of a leg of a right triangle if the other leg is 8 feet long and the hypotenuse i
iren [92.7K]
The <span>Pythagorean Theorem tells us that a^{2}+b^{2}=c^{2} where c is the </span><span>hypotenuse and a and b are the other two sides. To solve for one of the shorter sides we need to rearrange:

b=\sqrt{c^{2}-a^{2}}

We can then substitute known values, and solve:
</span>b=\sqrt{10^{2}-8^{2}}
b=\sqrt{100-64}
b=\sqrt{36}
b=6 feet

Solve 4x + 1 = 3 – 2x
romanna [79]

Answer:

x = 1/3

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

4x + 1 = 3 - 2x

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Add 2x on both sides:                    6x + 1 = 3
  2. Subtract 1 on both sides:                6x = 2
  3. Divide 6 on both sides:                   x = 1/3

<u>Step 3: Check</u>

<em>Plug in x to verify it's a solution.</em>

  1. Substitute:                    4(1/3) + 1 = 3 - 2(1/3)
  2. Multiply:                        4/3 + 1 = 3 - 2/3
  3. Add/Subtract:               7/3 = 7/3

Here we see that 7/3 does indeed equal 7/3.

∴ x = 1/3 is a solution of the equation.
