What is the value of n?
bogdanovich [222]

Answer:

<h3>B. 85°</h3>

Step-by-step explanation:

Look at the picture.

We know: Angles on one side of a straight line always add to 180°.

Therefore:

\alpha=180^o-142^o=38^o\\\\\beta=180^o-133^o=47^o

We know: the sum of the measures of the angles of the triangle is equal to 180 °.

Therefore:

\gamma+47^o+38^o=180^o

\gamma+85^o=180^o      <em>subtract 85° from both sides</em>

\gamma=95^o


n^o+95^o=180^o\to n^o=180^o-95^o=85^o

KonstantinChe [14]

Answer:

Step-by-step explanation:

According to the exercise we can say that the explanatory variable will be hours / weeks of study.

The response variable is GPA.

B

We definitely found that between the variables there is a weak or fragile relationship, neither negative nor positive nor linear.

C)

1.Observational study, since we observe that the only variables that will influence the results of the study are the observations of the students

2.No. This study is observational and its characteristics are not sufficient to conclude that studying more hours leads to obtaining a higher GPA.
