In fact, if a design still looks the same after some rotation, then it has Rotational Symmetry. In this context, this design can be an object, a figure, a thing, etc. So these characteristics is the typical quality or feature of this object, figure or thing. An example of rotational symmetry is the Ferris Wheel when it rotates about the center.
Answer:
Factoring the term we get
Step-by-step explanation:
We need to factor the term:
Factoring:
Taking (y+4) common
It cannot be further factored.
So, Factoring the term we get
Answer:
Step-by-step explanation:
a. Let, p be the parameter being tested. From the sample, 38% would erase all of their personal information.
-we know that the value of probabilities are in the range [0,1]:
-Given that 38% is the true value of the claim can be symbolically expressed as p=0.5
b. The null hypothesis usually represents the true value parameter under study.
-As stated above, the true value of the parameter is 38%;
-Hence, the null hypothesis is
#Alternative hypothesis is the control value, given the value of the parameter p=0.38, the alternative hypothesis is that p has a different value other than 0.39:
