Suppose we spin the wheel, observe the color that the pointer stops on, and repeat the process until the pointer stops on red. W
PIT_PIT [208]

The probability of spinning three times before getting red is 0.6084.

<h3>What is probability?</h3>

This is the term that is used in mathematics to show the likelihood of something happening.

We first solve for the probability of not getting red

P(not Red) = P(Blue) + P(Green) = 0.63+0.15 = 0.78

P(not Red) × P(not Red) = 0.78 × 0.78 = 0.6084

The probability of spinning at least three times will be 60.84 percent.

This gave 160 acres of land to new settlers out on the great plains so long as they "improved it.
exis [7]

The Homestead Act of 1862 gave 160 acres of land in the Great Plains in the western United States.  The law was signed on May 20, 1862, by  President Abraham Lincoln. The Homestead Act encouraged migration and opened up settlements to any American, including freed slaves, to own, use and improve the land.


The law required that the new settlers will have to pay a minimal filing fee and to live continuously on the land for five years for them to receive full ownership of the land.


By 1865 (the end of the Civil War), there were 15,000 homestead claims that have been established, with more following in the subsequent years.

The theory of plate tectonics can be used to explain all of the following except.
jok3333 [9.3K]

The theory of plate tectonics cannot be used in explaining: the origin of the Earth's core.

<h3>What is a tectonic plate?</h3>

A tectonic plate is also known as lithospheric plate and it can be defined as an enormous, solid, irregularly shaped rock slab, that comprises two (2) plates:

  1. Continental plates
  2. Oceanic plates

<h3>The theory of plate tectonics.</h3>

The theory of plate tectonics states that the solid outer crust of planet Earth (lithosphere) is typically divided into enormous (massive) slabs of solid rock (plates) that move over the asthenosphere, including the upper portion of the mantle.

<h3>The uses of the theory of plate tectonics.</h3>
  • It can be used to explain the presence of magnetic anomalies on the ocean floor.
  • It can be used to explain the geographical distribution of earthquakes and volcanoes.
  • It can be used to explain the presence of glacial deposits in tropical areas.
  • It can be used to explain the origin of mountains.
