9) Find the value of k if x = 3, y = 2 is a solution of the equation 2x + 3y = k.
10) Find the probability of selecting a girl child from a group of 5 boys and 2 girls.​

Answer 1

Step-by-step explanation:

4) 3x-2 =0

3x= 2

X= 2

3

therefore 2 is the zero of the polynomial

3

if you replace X with 2 and solve the sum you will

3 get zero

7) the degree is 1

8) the points (-3,-7) lie in the 3rd quadrant

9)2x+3y = k

2(3) + 3(2) = k

6+6=k

12=k

therefore k =12

10) Probability= no. of events

no. of total events

= 2 ( no.of girls )

7 ( total children )
