Answer: Using Chi-square.

Step-by-step explanation: To check if the provided data show any differences in preference for the two detergents (i.e., two variables), a Chi-square can be deployed, as it is used to test the goodness of fit, and test if two variables are related.

If the value obtained is less than 0.05, it means that there is statistical difference between the preference for the two detergents.

However, if the obtained value is higher than 0.05, it translates that there is no statistical difference between the preference for the two detergents.

Provide an Example of how to draw transformed figures that are translated, reflected, and rotated.
solniwko [45]

Step-by-step explanation:

Translations: When a figure is slid to another place on the coordinate grid (for example if i asked you to move the figure 2 units down and 4 units to the left)

Reflected: When a figure is reflected across the y-axis or the x-axis and both figures are congruent to each other.

Rotated: When a figure is rotated (for example if i asked you to rotate the figure 90 degrees)

Evaluate cos(tan^-1 0)
AlladinOne [14]

Answer:

cos(tan^{-1}(0))=1

Step-by-step explanation:

Evaluate cos(tan^-1 0)

cos(tan^{-1}(0))

We know that tan(0)=0

tan (0 degree)=0

tan^{-1}(0)=0

Replace it in our problem

cos(tan^{-1}(0))

cos(0)

At 0 degree the cos value is 1

So co(0)=1

cos(tan^{-1}(0))=1
