To find the mean of this set of data you must add all the numbers together, then divide by the numbers that you have. Since you have 5 numbers you would divide by 5 after adding them together.
1st: ADD!!
20 + 12 + 29 + 15 + 49 = 125
2nd: divide by 5!
125 ÷ 5 = 25
So the mean of this data set is 25.
Good Luck! :)
Answer:
1/2
Step-by-step explanation:
2/4 is equal to 1/2, because if you divide 4 by 2 you get 2, and if you divide 2 by 2 you get one.
Basically, the simplification process would look something like this...
2/4 ÷ 2/2 = 1/2
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.
Answer:
the third slide CRACKED me up XDDD
Step-by-step explanation:
<span>The number can be 102, 108, or 114. They can all be formed that way.
32 + 34 + 36 = 102
34 + 36 + 38 = 108
36 + 38 + 40 = 114
</span>The n<span>ext one is 120 . . . . . 38 + 40 + 42</span>
