Answer:

Step-by-step explanation:

There's only 1 angle to find.

45 + 57 + ? = 180                    All triangles have interior angles that add to 180.

102 + ? = 180                          Combined 45 and 57  Subtract 102 from both sides

? = 180 - 102                           Combine

? = 78

A maple tree is 16 yards tall and its shadow is 12 yards long. A nearby observation tower is 12 yards tall. How long is the obse
pashok25 [27]

Answer: 9 yards

Step-by-step explanation:

Given

The maple tree is 16 yards tall and its shadow is 12 yards tall

Suppose the angle made by the maple tree is x

\Rightarrow \cos x=\dfrac{12}{16}

For the tower also, the angle made by the tower and its shadow is x

Suppose the length of the shadow is y

\Rightarrow \cos x=\dfrac{y}{12}

Substitute the value of \cos x

\Rightarrow \dfrac{y}{12}=\dfrac{12}{16}\\\\\Rightarrow y=9\ \text{yards}

Points and their residual values are shown in the table. Which point is farthest from the line of best fit?
vredina [299]

Answer:

(3,6.2)

Step-by-step explanation:

Residual value the difference between the observed value of the dependent variable and the predicted value is called the residual.

Residual , R=O-P, where R is the residual value, O, is the observed value, and P is the predicted value. The sum and the mean of the residuals are equal to zero.

Now, we can see that the biggest <em>magnitude </em>of the difference is of -1.1 and -1.1 is at the point (3,6.2).  (\left | -1.1 \right |=1.1)

Therefore, the point farthest from the line of best fit is the one whose magnitude of residual value is the most and in this case that point is (3,6.2).
