<h3>
Answer: D) 4</h3>
===========================================================
Explanation:
The width of the confidence interval is 20-12 = 8 units. That cuts in half to get 8/2 = 4 which is the margin of error.
The center of the confidence interval is (12+20)/2 = 32/2 = 16. Add four onto this to get 16+4 = 20, which is the right endpoint. Subtract four from the center to get 16-4 = 12, which is the left endpoint.
Effectively, it's like saying "an archer aims for the value 16 on the number line, and the arrow could land as high as 20 or as low as 12".
The length of the third side of the triangle will be 4 centimeters if it is a right-angled triangle.
<h3>What is a triangle?</h3>
A triangle is a geometric shape having three sides and the area is equal to 270 degrees. A right angle triangle is one where the angle of one side is exactly 90 degrees.
If two sides measure 3 and 5 centimeters, the triangle will have a right angle if the third side measures around 4 centimeters.
Hence, the third side of the triangle will be 4 centimeters.

The answer is b, 5 degrees. The equation means that the temperature will be 61.4 degrees + 5 degrees each hour until 4 pm.
Due to constructive interference, we can predict that: C. the resulting wave would travel at 4.2 hertz.
<h3>What is constructive interference?</h3>
Constructive interference of a wave can be defined as a phenomenon through which two waves of the same frequency and phase combines to form a wave of higher magnitude.
This ultimately implies that, the constructive interference of a wave causes an increase in the amplitude or frequency of waves.
Due to constructive interference, we would have:
Wave = 3 + 1.2
Wave = 4.2 hertz.
