Some please help with this problem, I have tried multiple time but still couldn't get the right answer. :(

Tanzania [10]

Given data:

Total number of songs = 8

Rock songs = 3

Reggae songs = 2

Country songs = 3

Probability = Number of favorable outcomes / Total number of outcomes

To find:

When song is selected randomly to play first song and then second song from remaining ones ,

Probability when both the songs are from Reggae songs,

$\begin{gathered} P\text{ =}\frac{2}{8}\times\frac{1}{7} \\ \text{ = }\frac{2}{56} \end{gathered}$ $P=\frac{1}{28}$

Thus , the probability is 1/28.

iren [92.7K]

Answer:

Since we extract n elements in total, the algorithm for the running time for K sorted list is O (n log k+ k) = O (n log k)

Step-by-step explanation:

To understand better how we arrived at the aforementioned algorithm, we take it step by step

a, Construct a min-heap of the minimum elements from each of "k" lists.

The creation of this min-heap will cost O (k) time.

b) Next we run delete Minimum and move the minimum element to the output array.

Each extraction takes O (log k) time.

c) Then insert into the heap the next element from the list from which the element was extracted.

Now, we note that since we extract n elements in total, the running time is

O (n log k+ k) = O (n log k).

So we can conclude that :

Since we extract n elements in total, the algorithm for the running time for K sorted list is O (n log k+ k) = O (n log k)

Translate Δ A B C 6 units horizontally. How are the values in the ordered pairs affected by the translation?

snow_tiger [21]

Answer:

The x-coordinates are translated 6 units to the left or right while the y-coordinates are not affected.

Step-by-step explanation:

The given triangle has vertices at A(-4,1), B(-2,1) and C(-2,4)

The transformation rule for a horizontal translation by k units is

$(x,y)\to (x\pm k,y)$

In this case we have k=6

$A(-4,1)\to A'(-4\pm6,1)$

$B(-2,1)\to B'(-2\pm6,1)$

$C(-2,4)\to C'(-2\pm6,4)$

Therefore the x-coordinates are translated 6 units to the left or right while the y-coordinates are not affected.
