Mean : The average of all the data in a set.

Median : The value in a set which is most close to the middle of a range.

Mode : The value which occures most frequently in a data set.

12,9,12,11,10,18,7,19,13,19

Mean = 13 (Average)

Median = 12 (Middle)

Mode = 12, 19 (most common)

ere is a picture of a cube and the net for this cube. What is the surface area of this cube? A. 1,350 mm2 B. 450 mm2 C. 225 mm2
lord [1]
Hello!

To find the surface area of a cube you do 6a^{2} where "a" is the length of one of the sides.

So 6 *15^{2} = 1350

the answer is 1350mm^{2}

Hope this helps!

Does anyone know how to do this ?

Answer: D) 32

Step-by-step explanation:

The area of a parallelogram equals its base times its height. Substitute the base and area into this formula to solve for the height:

A=bh

40=(5)(h)

h=8

If ABCD is a parallelogram, opposite sides are parallel, so AB is parallel to DC. If AB is parallel to DC, EB is parallel to DC. Since EB is parallel to DC, quadrilateral EBCD has at least one pair of parallel sides, making it a trapezoid. The area of a trapezoid is equal to \frac{h(b_{1}+b_{2})  }{2} where h is the height, b_{1} is one base, and b_{2} is the other base. Plug the necessary values into the formula:

A=\frac{h(b_{1}+b_{2})  }{2}

b_{1} =AB-AE\\DC=AB\\b_{1} =DC-AE\\b_{1} =5-2\\b_{1} =3

b_{2} =5

h=8

A=\frac{8(3+5)}{2}

A=32

The answer is D) 32.
