F(2) is referring to the 2 on the x-axis. You can see that the point aligning with 2 on the x-axis is also 2 on the y-axis. Therefore, f(2)=2! hope that helped
First, find the probability of picking one 9. There are four nines in a deck of 52, so the probability is 4/52, which is 1/13.
The probability of picking a 9 the second time is 1/17, because if a 9 was picked the first time, then there are three 9s left and 51 cards left in total.
To find the probability of both events happening, multiply the individual probabilities together:
(1/13)(1/17)
The probability that both cards picked will be 9s is 1/221.

Step-by-step explanation:
I think I have helped you before with this problem, substitute x and y with -3 and 8 respectively, so 5*(-3)+8b=17, -15+8b=17, 8b=32, divide both sides by 8 and you get b=4
First, how many periods of 6 hours are in 24 hours? 24 / 6 = 4.
So every 6 hours, Katie needs 2.5 drops.
Seeing as there are 4 periods of 6 hours in 24 hours, you would do 2.5 x 4.
Katie will receive 10 drops of medication in 24 hours.
