yanalaym [24]
To find the mean, you need to find the average. The equation that I used was 61(1)+64(3)+67(5)+70(6)+73(5) and then divided that total by the total number of 20.

The answer would be D) 68.5

Can y’all help find the surface area please and thank you
solong [7]

<u>To find the area of a complex shape</u>:

 ⇒ must cut the whole shape into a simpler shape

  • square with side lengths of 4 in
  • 2 triangles with a base of 4 in. and a height of 8 in.
  • 2 triangles with a base of 4 in. and a height of 10 in.

<u>Let's calculate:</u>

  • Area of 2 triangles with a base of 4 in. and a height of 8 in.

             Area = \frac{1}{2}*4*8 + \frac{1}{2}*4*8=16+16=32\\

  • 2 triangles with a base of 4 in. and a height of 10 in.

             Area = \frac{1}{2}*4*10 + \frac{1}{2}*4*10=20+20=40

  • square with side lengths of 4 in

             Area = 4 * 4=16

<u>Total Area</u>: 32 + 40 + 16 = 88 in²

<u>Answer: 88 in²</u>

<u></u>

Hope that helps!

What is the solution to this equation
il63 [147K]
One equation is a multiple of the other, so you have an infinite solution set and for every x you pick you can find a matching y to fulfill both equations

7x-3y=9\\&#10;7x-9=3y\\&#10;\frac{7x}{3}-3=y

this forms a line and any of its points is valid in the equation
