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.

Answer:

The measure of the angle ABD is:

m∠ABD = 122°

Step-by-step explanation:

Given

m∠ABC = 84°

m∠CBD = 38°

To determine

Find m∠ABD

The given diagram shows that m∠ABD is the sum of m∠ABC and m∠CBD.

In other words,

m∠ABD = m∠ABC + m∠CBD

substituting m∠ABC = 84° and m∠CBD = 38°

m∠ABD = 84° + 38°

m∠ABD = 122°

Therefore, the measure of the angle ABD is:

m∠ABD = 122°

Answer:

chisquare = 31.667

degree of freedom = 2

Step-by-step explanation:

Formula for chisquare test =  (O-E)²/E

total number observations= 60 + 25 + 15 = 100                  

Estimated E,

80% x 100 = 80

15%x100 = 15

5% x 100 = 5

chisquare =

\frac{(60-80)^{2} }{80} +\frac{(25-15)^{2} }{15}+\frac{(15-5)^{2} }{5}\\

= 5 + 6.67 + 20

= 31.667

from the calculation above the value of the chisquare statistic = 31.67

the degree of freedom is the number of samples in the test  n - 1

= 3-1

= 2

I have solve this question also in a tabular form to aid understanding in the file i uploaded.

thank you and good luck!
