Question

if the mean of 8,6,9,p+15 and p+2 is 10, find the value of p & after finding the value of P write down all the observation in ascending order and find its median and mode ?​

Answer 1

Answer:

good morning

Answer 2

P= 5.

ascending order = 6,7,8,9,20.

median= 8.

mode= null.

Step-by-step explanation:

given observation = 8,6,9,p+15,p+2

MEAN = 10.

• 8+6+9+p+15+p+2 = 10
• 5

= 40+2p = 10*5

=. 40+2p = 50

=. 2p = 50-40

=. 2p = 10

= p= 10/2

= p = 5.

therefore, observations = 8,6,9,20,7.

ASCENDING ORDER:

6,7,8,9,20.

MEDIAN:

no.of.observations n = 5 (odd)

median = n+1/2 th term.

= 5+1/2

= 6/2

= 3rd term.

6, 7, 8, 9, 20.

therefore third term = 8

median = 8.

MODE:

Repeating term is mode.

there is no repeating term

therefore mode is null.
