Answer:
The total number of samples that give this outcome is 5.
Step-by-step explanation:
Since Y takes values in {0,1,2,3}, For us to have that 
implies that all of them are zero but one. The one that is non-zero necessarily is equal to 1. To calculate the number of samples that give this outcome is equivalent to counting the total number of ways in which we can pick the i-index such that 
. Note that in this case we can either choose Y1 to be 1, Y2 to be 1 and so on. So, the total number of samples that give this outcome is 5.
A snail travels at a rate of 2.58 feet PER MINUTE. After 9 minutes, it will travel 2.58 * 9 feet.
2.58 * 9 = 23.22 feet.
The snail travels 23.22 feet in 9 minutes.
You can see that it travels 2.58 feet per minute. In the next minute, it will travel another 2.58 feet. And so on until the 9th minute passes. This is the same as:
2.58 + 2.58 + 2.58 + 2.58 + 2.58 + 2.58 + 2.58 + 2.58 + <span>2.58 = 9 * 2.58 = 23.22</span>

Answer: 8 (The second option).
Step-by-step explanation:
1. To solve this exercise you draw a line to a point O, this lines will bisect the angle of Z∠60°. Then will obtain two into two right triangles with two angles of 30° at the point Z.
2. The lenght XY will be twice the lengt XO or YO.
3. Let's calclate XO as following:
4. Then, XY is:
