Answer:
(3, 10)
Step-by-step explanation:
f(3) means substitute the value of x = 3 into f(x)

Therefore, when x = 3, y = 10
So the ordered pair is (3, 10)
Answer: 
Step-by-step explanation:
Given
There are 8 red and 4 blue beads
Three beads were taken from the box
(i)No of ways of choosing three red beads out of 12 beads is 
Total no of ways 
Probability is

(ii)atleast two beads refers to minimum two beads
There can be two possibilities (2B,1 R), (3B, 0R)

Remember that percent means parts out of 100
x/100
discount is the decrease
so we divide the decrease by the original total and get
100/5775=0.0173
convert to fraction
0.0173/1
make bottom number 100
multiply by 100/100
1.73/100=1.73%
round
2%
Answer:
a=-8 b=2
Step-by-step explanation:
x^2+6x-16
x^2+(8-2)x-16=0
x^2+8x-2x-16=0
X(X+8)-2(X+8)=0
(X+8)(x-2)=0
Compare with (X+a)(X+b)
Where we get a=-8 b=2
