Question

for what value of 'a' 4,6,a,9,10,19 will 7.5 be the median ​

Answer 1

Answer:

a = 6

Step-by-step explanation:

Given that the numbers are 4, 6, a, 9, 10 and 19.

/* Median is the number that is in the middle. */

/* There are 6 numbers,  the median will be half of the middle two */

Median = (a + 9)/2

/* It is given that 7.5 is the median. */

(a + 9)/2 = 7.5

a + 9 = 15

a = 6

Answer: a = 6

Answer 2

Answer:

as we have to find median and a is not given.

median=a+9÷2=7.5( bcoz we don't know the correct median.)median is the middle most number.

a+9=15

a=15-9

a=6 is the answer my friend.
