Question

Do question 9 and 10

Answer 1

Answer:

Step-by-step explanation:

Q9: 3x+4y=6

3x=6-4y

x=2*(3-2y)/3

point is (3,2)

herex=3 and y=2

putting the value in

3x+4y=6

LHS=3*3+4*2

=9+8=17

17≠6

So point(3,2) does not lie on the line 3x+4y=6

=============================================================

Q 10

A is the mean of 5 and 25

so a=(5+25)/2

=30/2=15

So data are

24,23,a,a-1,12,26

or 24,23,15,14,12,26

arranging in ascending order

12,14,15,23,24,26

Here median =

mean of 15,23

=(15+23)/2=38/2

=19
