A = 6 * a² * sin(α)

V = a³ * (1-cos(α)) * √1+2cos(α)

Sorry, i don't know any examples .

−−→AB=(xy)<br><br> What values should <br> x<br> and <br> y<br> take?
laiz [17]

The values of x and y are 2 and 0, respectively

The complete question is given below:-

−−→AB=(xy) a line is given in the question from the image given in the question What values should x and y take?

<h3>How do determine the value of x?</h3>

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

From the graph, we have the following highlights:

Point A is at:

A = 2

The point B is located at:

B = 0

The coordinate (x,y) is represented as:

(x,y) = (A,B)

So, we have:

(x,y) = (2,0)

Hence, the values of x and y are 2 and 0, respectively

A study was conducted using data collected on the birth weights of a random sample of 10 pairs of identical twins to determine w
velikii [3]

Answer:

Null hypothesis (H_{0}): The birth weight of the first born of identical twins is the same as the birth weight of the second born.

Alternative hypothesis (H_{1}): The birth weight of the first born of identical twins is higher than the second born.

Step-by-step explanation:

Please note that the null hypothesis is the hypothesis we always want to reject or prove to be false. Hence in this study, the objective of the study is clearly stated that the researcher want  to determine whether the twin born first tends to weigh more than the twin born second.

Therefore, the null hypothesis we assume that the weight of the identical twins is the same regardless of who come first or last., while the alternative hypothesis is constructed or stated to answer the research objective.
