Answer:

We can conclude that on this case we have identical processes but excersise 17 use another way to present the probability distribution and as we can see the expected value can be viewed as a dot product of two vectors with one vector containing the outcomes and the other the probabilities for each possible outcome.

Step-by-step explanation:

Assuming this previous info:

Exercise 17. Suppose that we convert the table on the previous page displaying the discrete distribution for the number of heads occurring when two coins are flipped to two vectors.

Let vector

Find the surface area of the figure below.

gayaneshka [121]

Answer:

261 cm²

Step-by-step explanation:

To find the surface area of a square pyramid, you must first recognize all of the shapes.

There are four triangles and one square.

To find the area of a square, multiply the side by itself twice.
To find the area of a triangle, multiply the base and the height, then multiply the product by 1/2.

The triangles have a base of 9 and a height of 10.

$9*10=90$

Multiply the product by 1/2.

$90*1/2 = 45$

There are four triangles.

$45*4=180$

The area of all three triangles is 180 centimeters; the area of a single triangle is 45 centimeters.

There square has sides of 9 centimeters.

$9*9=81$

The area of the square is 81 centimeters.

Lastly, we add the areas of the shapes.

$45+45+45+45+81 = 261.$

Therefore, the surface area of this square prism is 261 cm².

You can use this layout to find the surface area of a square pyramid.

Draw a model to represent 5×3

stellarik [79]

Sorry for the drawing but what you do is add the boxes dont multiply so it will be t plus 5 plus 5 equal your answer
or 3 plus 3 plus 3 plus 3 plus 3 equals your answer
