Answer:

FALSE

Step-by-step explanation:

A random variable is a variable whose outcome depends on random criteria, such as a lottery game in which any number can be drawn randomly. That way, a randomized experiment will have random results that are not predetermined. For example, if the lottery has 80 numbers, the random variable function can achieve any result, which will depend on random criteria such as the luck of the player.

Find the Surface Area
Sergeeva-Olga [200]

Answer:

120 km squared.

Step-by-step explanation:

The shape shown has 5 sides: three rectangles and 2 triangles.

If you examine each triangle closely, they are 3-4-5 triangles. The area of one triangle is 3 * 4 * 1/2 = 12 * 1/2 = 12 / 2 = 6. Since there are two triangles, the total area of the triangles is 6 * 2 = 12 km squared.

The three rectangles have the same length, but their widths differ. They all have a side length of 9 km, but the largest rectangle has a width of 5 km, the medium has a width of 4 km, and the smallest has a width of 3 km.

So, the rectangles' areas added up will be (9 * 5) + (9 * 4) + (9 * 3) = 45 + 36 + 27 = 108 km squared.

And so, the total surface area is 12 km squared + 108 km squared, or 120 km squared.

Hope this helps!
