Answer:

51 cm^2

Step-by-step explanation:

To find the area excluding the shaded triangle, first find the area of the whole figure:

12 x 6 = 72cm^2

Now, find the area of the triangle:

(7 x 6) / 2

42/2

21cm^2

Lastly, subtract the shaded area from the whole:

72 - 21 = 51 cm^2

What is theoretical vs experimental probability? Please help!
mrs_skeptik [129]

Answer:

See down below.

Step-by-step explanation:

Theoretical probability is what we expect to happen. For example, we do a test of flipping a coin. You know that its either gonna be heads or tails.

Experimental probability is what actually happens when we try it out. It occurs when we are doing an experiment and then something happens.

Hope this helps!

a trapezoid with base measure of 23 km and 29km an area of 390km . find the height of the trapezoid.
cupoosta [38]
Hello!

To find the area of a trapezoid you use the equation

A =  \frac{a+b}{2} h

Put in the values you know

390 =  \frac{23+29}{2} h

Add

390 = \frac{52}{2} h

Divide

390 = 26 * h

Divide both sides by 26

15 = h

The answer is 15km

Hope this helps!
