Answer:
<em>In order to begin reducing pollution, the United States needs to reduce fossil fuel levels by 20 percent in the next five years.</em>
Explanation:
A thesis statement summarizes in one phrase or sentence the main idea or position that will be presented or argued for, it does not talk about facts, it is not an opinion or a question.
In this speech as the topic is preserving the environment the best thesis statement would be “In order to begin reducing pollution, the United States needs to reduce fossil fuel levels by 20 percent in the next five years.”
Why is preserving the environment important? (this option is a question, so it cannot be a thesis statement); The trees in the park are forty-five years old and provide shade in summer and protection from the elements in winter. (this option have facts, so it cannot be a thesis statement); Our town can reduce the need for landfills if we start a recycling program. (this option is more like an opinion, it does not state an efficient position, so it cannot be a thesis statement).
Archaeologists have studied many of the ancient cities of the Mayans such as Tikal, Calakmul and Copan. They studied the glyphs left
If there are especially few frequencies on the left cease of the abscissa on a frequency polygon when compared to the right quit, the curve is: Negatively skewed.
Definition: Frequency is the measurement of the number of instances that a repeated occasion happens in line with a unit of time. The frequency of wave-like patterns together with sound, electromagnetic waves (which include radio or light), electric signals, or other waves, expresses the range of cycles of the repetitive waveform in line with the second.
The time period frequency refers back to the variety of waves that pass a hard and fast point in unit time. It also describes the wide variety of cycles or vibrations passed through at some stage in one unit of time by a body in periodic movement.
Frequency is a crucial parameter used in technological know-how and engineering to specify the temporal price of exchange determined in oscillatory and periodic phenomena, together with mechanical vibrations, audio signals (sound), radio waves, and light.
Although the standard definition of frequency is based on occasions in keeping with 2d, different units of time may be used, consisting of minutes or hours. for instance, a human heart may beat at a frequency of sixty-eight beats according to the minute. A 78 report on a turntable turns at a charge of 78 revolutions according to a minute or seventy-eight rpm.
