The data consists of 25 observations - this is just how many people were involved in the study. (count the rows, excluding the header)
As for number of variables, that depends on the aim of the study. More likely than not, I suspect the name of each person involved is irrelevant, which leaves 7 variables. (count the columns, excluding the first)
Answer:
21°
Step-by-step explanation:
Since these are both equivalent right triangles, ∡RQY and ∡PQY are the same. So set them equal to each other.
16x-27=5x+6
x=3
Next plug x into ∡RQY
16(3)-27=21°
Hi!
<h3>Divide by -10 on both sides. </h3>
-10x/-10 < -100/-10
<h3>The inequality sign flips because we are dividing by a negative number. </h3>
<u>x > 10</u>
<h2>The answer is A x > 10</h2>
Hope this helps! :)
