Answer:
it is 3 because the 3 is in circle
the answer is B because to get the total cost, first divide 450 by 50. This gives us 9. We then multiply 9 by $600 to get a total of $5400.
Total amount: 16
Red socks: 4
Probability of picking a red sock 4/16
If we take a red sock out and do not replace it, we are left with a total of 15 socks.
Blue socks: 6
So the probability of picking a blue sock will be 6/15
Multiply:
4/16 * 6/15 = 24/240 = 1/10

Answer:
inverse: y=sqrt(x)-9
domain: (0, +inf)
Step-by-step explanation:
y=(x+9)^2
sqrt(y)=x+9
x=sqrt(y)-9
inverse: y=sqrt(x)-9
domain: (0, +inf) bc you cant have a square root of a negative number
