3 0
2(3) + 3(4) + 4(16) + 5(22)
Multiply
6+12+64+110
Add
192
Divide by the total amount of testers
192/((3+4+16+22))
192/45
Divide
About 4.22

Because all the scores are whole numbers, the average score is a 4

I hope this Helps!

What is the distance between points M and N?
Free_Kalibri [48]

By using <em>triangle</em> properties and the law of the cosine twice, we find that the distance between points M and N is approximately 9.8 meters.

<h3>How to determine the distance between two points</h3>

In this problem we must determine the distance between two points that are part of a triangle and we can take advantage of properties of triangles to find it. First, we determine the measure of angle L by the law of the cosine:

\cos L = \frac{(19.6\,m)^{2}-(14.8\,m)^{2}-(21.4\,m)^{2}}{-2\cdot (14.8\,m)\cdot (21.4\,m)}

L ≈ 62.464°

Then, we get the distance between points M and N by the law of the cosine once again:

MN = \sqrt{(7.4\,m)^{2}+(10.7\,m)^{2}-2\cdot (7.4\,m)\cdot (10.7\,m)\cdot \cos 62.464^{\circ}}

MN ≈ 9.8 m

By using <em>triangle</em> properties and the law of the cosine twice, we find that the distance between points M and N is approximately 9.8 meters.

What is 243.00 minus 15% discount?
balu736 [363]
100-15=85
Therefore 0.85 is the multiplier
So 243.00 times by 0.85 = 206.55
