Mean is the "meanest" because it requires the most work. Add up the values in your data set and divide by the number of terms in the data.

Let x represent attendees at Harry's Hoedown, then

Mean = \frac{Martha's (M) + Shirly's (S)  + Harry's (x) }{3}

41 = \frac{48 + 33 + x}{3}

123 = 48 + 33 + x

123 = 81 + x

42 = x

Which best explains why this triangle is or is not a right triangle?
erastovalidia [21]

Answer:

<h2>This triangle is a right triangle:</h2><h2>36² + 15² = 39².</h2>

Step-by-step explanation:

If a ≤ b <c is the length of the sides of a right triangle, then:

a^2+b^2=c^2

We have

a=15\ in,\ b=36\ in,\ c=39\ in

Check the equality:

L_s=15^2+36^2=225+1296=1521

R_s=39^2=1521

L_s=R_s

It's a right triangle.
