The following two-way table describes student's after school activites. Find the probability that a randomly selected student is
stiv31 [10]

The probability that a randomly selected student is in music/drama is 25%

<h3>How to determine the probability?</h3>

From the table, we have the following values

Music/Drama = 7 + 13 + 5 = 25

Total = (20 + 20 + 25 + 7 + 13 + 5 + 3 + 2 + 5) = 100

The probability is then calculated as:
P = Music/Drama / Total

So, we have:

P = 25/100

Express as percentage

P = 25%

Hence, the probability that a randomly selected student is in music/drama is 25%

A line segment has endpoints P(-1,5)and Q(5,2) find the coordinate of that trisect the segment​
musickatia [10]

Answer:

(1, 6).  The second is (-1 + 2 + 2, 1 + 1 + 1), or (3, 3)

Step-by-step explanation:

Moving from P to Q, we see that x increases by 6  and y increases by 3.

"Trisect" means "divide into three equal subintervals."

We find (1/3) of 6 (which comes out to 2) and (1/3) of 3 (which comes out to 1).  

Thus, the first junction (between 1st and 2nd trisection) is (-1 + 2, 5 + 1), or (1, 6).  The second is (-1 + 2 + 2, 1 + 1 + 1), or (3, 3)

2^n-5×5^n-4=5
Papessa [141]

\huge{\fbox{\sf{n=5 }}}

Step 1:

⇒ {2}^{n - 5}   \times  {5}^{n - 4}  = 5

Step 2:

⇒{2}^{n - 5}  \times  {5}^{n - 4}  =  {5}^{1}  \times  {2}^{0}

On comparing values we get:

Taking:

{2}^{n - 5}  =  {2}^{0}

n-5=0

n=5✓

or

Taking:

{5}^{n - 4}  =  {5}^{1}

n-4=1

n=5✓
