Explain how you can use the inscribed angle theorem to justify its second corollary, that an angle inscribed in a semicircle is
Katarina [22]
Prove:

The angle inscribed in a semicircle is a right angle. 

The inscribed angle theorem states that the angle θ, inscribed in a circle is half the measure of the central angle of the circle. So, if the given is a semi-circle, then the inscribed angle is half of 180, therefore, 90 degrees and a right angle.  <span />

Which statement is true about a trend line? A regression line and a trend line are opposite terms. A regression line and trend l
kicyunya [14]

Answer:

A is incorrect!  <u>B. should be the correct answer</u>

Step-by-step explanation

After some research, i found that the correct answer is most likely <u><em>B.  a regression line and trend line are equivalent terms</em></u>

<em />

<em>A trendline and a regression can be the same. </em>

<em> A regression line is based upon the best fitting curve Y= a + bX Most often it’s a least-squares fit (where the squared distances from the points to the line (along the Y-axis) is minimized). </em>

<em> It can be quadratic or logistic or otherwise, but most often it is linear. </em>

<em> A trendline is often constructed by smoothing of the results, making it less peaked. (often by using a moving average); but can also come from ARIMA projections or curve fitting techniques (such as regression).</em>

Let me know if i helped you!

Z to the power of 2 =1
stiv31 [10]

That would be written as:

z^{2} = 1


And the step-by-step equation would be:

z^{2} = 1 → we take the 2 to the right side of the equation and do the IO*

z = \sqrt{1} →we solve for \sqrt{1}

z = 1 → final answer


*Ps - IO is not an existing term and stands for inverse operation. In this case, because when we take to 2 to the right side of the equation (the 2 is a power) it'll have to turn into a square root (because exponents and roots are inverse operations)



Hope it helped,
