Answer:
18
Step-by-step explanation:
120 times .15 to get 18
Answer:
Option C - 9 AU
Step-by-step explanation:
To find : What is the average distance from Planet B to the star?
Solution :
According to kepler's law,
The squares of the sidereal periods (of revolution) of the planets are directly proportional to the cubes of their mean distances from the Sun.
i.e. 
We have given,
The average distance from the star to Planet A is 
AU.
It takes 432 Earth days for Planet A to orbit the star i.e. 
It takes 1,460 days for Planet B to complete an orbit i.e. 
Substitute the values in 
Taking root cube both side,
![\sqrt[3]{0.0875}=\frac{4}{S_2}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B0.0875%7D%3D%5Cfrac%7B4%7D%7BS_2%7D)
The average distance from Planet B to the star is 9 AU.
Therefore, Option C is correct.
Answer:
Fail to reject H₀
Step-by-step explanation:
To reject the null hypothesis, the P-value must be less than 0.05.
Since the P-value is 0.15 which is greater than 0.05, we would fail to reject the null hypothesis as there is no sufficient evidence against the null hypothesis.
Thus, the conclusion would be to fail to reject H₀.
Answer:
(b) Both vertical and horizontal reflection
Step-by-step explanation:
The figure will be a horizontal reflection of itself about any vertical line through two of the smaller 6-pointed stars.
The figure will be a vertical reflection of itself about any horizontal line through two of the smaller 6-pointed stars.
the pattern has both vertical and horizontal reflection
__
<em>Additional comment</em>
A pattern will have horizontal reflection if there exists a vertical line about which the pattern can be reflected to itself. That is, there exists one (or more) vertical lines of symmetry.
Similarly, the pattern will have vertical reflection if there is a horizontal line about which the pattern can be reflected to itself. Such a line is a horizontal line of symmetry.
