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.

solniwko [45]

Answer:

Median = 13

Step-by-step explanation:

We are given the following data:

16, 15, 13, 12, 17, 14, 11, 9, 11

Formula:

Median:\\\text{If n is odd, then}\\\\Median = \displaystyle\frac{n+1}{2}th ~term \\\\\text{If n is even, then}\\\\Median = \displaystyle\frac{\frac{n}{2}th~term + (\frac{n}{2}+1)th~term}{2}

Sorted data: 9, 11, 11, 12, 13, 14, 15, 16, 17

Median =

=\dfrac{9+1}{2}^{th} = 5^{th}\text{ term} = 13

Thus, the median of the given data is 13.

Harman [31]

Answer: It’s...

Step-by-step explanation: All of these numbers are going backwards by -4. Just keep subtracting. But then again, it will take you ages. So... try multiplying 51 by -4. Then -86 - whatever total you got. I have no clue if this will help. Is this even an assignment for you or a trick question?

Doss [256]

Answer:

803.84 in^3

Step-by-step explanation:

First of all we have to find the base area

base area = radius^2 x 3.14 = 8^2 x 3.14 = 64 x 3.14 = 200,96 in^2

the volume can be find with this formula:

V = (base area x height)/3

V = (200.96 x 12)/3 = 803.84 in^3
