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.

Line / is shown on the graph below. If another line is drawn, perpendicular to line I, what must be its slope?
juin [17]

Answer:

Undefined

Step-by-step explanation:

The slope on the graph is horizontal so there's no slope and the answer is just y = 3

For a line to be perpendicular to a horizontal line, it is going to be a vertical line.

All vertical lines have an undefined slope.

FIND THE SUM OF 20 TERMS OF THE ARITHMETIC SERIES IN WHICH 3rd TERM IS 7 AND 7th TERM IS 2 MORE THAN THREE TIMES ITS 3rd TERM
algol13

Answer:

740

Step-by-step explanation:

The n th term of an arithmetic series is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₃ = 7 and a₇ = (3 × 7) + 2 = 21 + 2 = 23 , then

a₁ + 2d = 7 → (1)

a₁ + 6d = 23 → (2)

Subtract (1) from (2) term by term

4d = 16 ( divide both sides by 4 )

d = 4

Substitute d = 4 into (1)

a₁ + 2(4) = 7

a₁ + 8 = 7 ( subtract 8 from both sides )

a₁ = - 1

The sum to n terms of an arithmetic series is

S_{n} = \frac{n}{2} [ 2a₁ + (n - 1)d ] , thus

S_{20} = \frac{20}{2} [ (2 × - 1) + (19 × 4) ]

     = 10(- 2 + 76) = 10 × 74 = 740

A triangle is formed using three given side lengths. Do these lengths always forma unique triangle? Explain.​
ollegr [7]
No, these do not always forma unique triangles because it depends on what size your sides are because if you have 3 sides of the same length then that’s a equilateral and if you have two sides of the same length and one side that’s not then that would be an Isosceles triangle and if you had no sides of the same length then that would be a scalene triangle.
