A survey was taken of students in math classes to find
Pie
I’m guessing you meant central tendency.

I’d say the mean is the best measure for period 2. This is because it doesn’t have any extremely low or high values which could distort the mean value.

If it did ie. 8, then I would choose median as it is less affected by anomalous results

Pentagon JKLMN is similar to pentagon UVWXY.
marusya05 [52]

9514 1404 393

Answer:

  C.  12

Step-by-step explanation:

Corresponding sides are proportional. Sides with the same mark are the same length.

  WX/XY = LM/MN = LM/KJ

  WX/10 = 18/15

  WX = 180/15 . . . . multiply by 10

  WX = 12

This problem can be completed in 2 ways. Both are acceptable.

Option 1:


This is an isosceles trapezoid that can be divided into a rectangle and two congruent triangles.

The area of the rectangle is the base times the height.

9 \times 4=36

The area of one of the triangles is half the base times the height.

\dfrac{1}{2} \times 5 \times 4 = 10

The other triangle must have that area too.

36+10+10=56

The area is 56 square centimeters.

Option 2:

We can use the area formula for the trapezoid.

A=\dfrac{b_1+b_2}{2} \times h

Where b_1 is the length of the shorter base
and b_2 is the length of the longer base
and h is the height.

The length of the shorter base is 9.
The length of the longer base is 9+5+5, or 19.

The height is 4.

A=\dfrac{9+19}{2} \times 4

=56

Same answer. The area is 56 square centimeters.

Both options are two acceptable ways the problem can be tackled.
