To find the average of an amount of numbers, we simply add them up and divide them by the amount of numbers we have. For example, if we have 1,2, and 3 as our numbers, we can see that we have three numbers. Next, we add them up to get 1+2+3=6. Lastly, we divide 6 by the amount of numbers we have (3) to get 6/3=2 as our average. Applying that here, we see that there are four numbers. Next, we add them up using a calculator to get 5,678.54+3,665.77+4,231.98+4,768.99 =18345.28 . Finally, we divide that number by the amount of numbers we have (using a calculator) to get 18345.28/4=4,586.32, making B your answer.

Step-by-step explanation:
Answer:
true
Step-by-step explanation:
it is true because there is one input for y output
The formula of a trapezoid is the sum of the both bases multiplied by the height then divided by 2.
Answer:
<u>The correct option is:</u>
m∠R ≅ m∠N; this can be confirmed by translating point R to point N.
<u>Step-by-step explanation:</u>
ΔPQR, is a dilation of ΔLMN by a scale factor of 3 from the center of dilation at point M.
Which mean that the point M overlap the point Q, the point L translated to the point P and the point N to the the point R
So, ∠M=∠Q , ∠L=∠P , ∠N=∠R
And we should know that the dilation of triangles makes it similar.
And AA similarity postulate mean : the triangle will be similar when two pairs of corresponding angles are equal.
So, the correct answer will be the fourth option
<u>m∠R ≅ m∠N; this can be confirmed by translating point R to point N.</u>
