I was hoping someone could help explain this I saw an answer and the step by step included this in it

When you look at the data, in the first column, the frequency of sales of both are similar. Even the second column shows similar data. **Association is determined if there is a significant difference between the data in each column/row depending on what you are aiming to answer.**

In this case, we look at it per column because you want to compare the frequencies of sales of each company which are aligned by columns. So we know to look at the columns and not the rows.

I put 2 stars around the part that Im talking about, but I was wondering if someone could explain it a bit more thanks :)

You have learned about the six trigonometric functions, their definitions, how to use them, and how to represent them graphically. the sine, cosine, and tangent trigonometric functions can be paired with their reciprocal functions, cosecant, secant, and cotangent, respectively. think about how each function is related to its reciprocal function.how are the graphs of the reciprocal functions related to their corresponding original functions? what happens to the graphs of the reciprocal functions as x approaches the zeros of the original functions? describe how you would teach friends with different learning styles (visual-spatial, aural-auditory, verbal-linguistic, physical-bodily-kinesthetic, logical-mathematical, social-interpersonal, and solitary-intrapersonal) how to graph the reciprocal functions

60 2(x + 2) in the diagram, gef and hef are congruent. what is the value of x?

Solve 2 - 3 cos x = 5 + 3 cos x for 0° ≤ x ≤ 180° a. 150° b. 30° c. 60° d. 120°
