2.5 your welcome I think so I really don’t know tell me if I’m wrong
Step-by-step explanation:
There are 25 marbles altogether.
When you pick the 1st marble, there's a 5/25 chance that you pick a red marble.
When you pick the 2nd marble, there's a 15/24 chance that you pick a blue marble.
Why did it become 24? Because you already pick the 1st marble.
So since each probability is independent from each other, the total probability can be found by multiplying both probabilities, which is 1/8.

Answer:
11
Step-by-step explanation:
10×4/5+(8×3/4-6×1/2)=8+6-3=14-3=11
The formula for the general sin function is
where b is the period and c is the phase shift. We are given a period of
and the formula to solve for b is
. We set up to solve for b:
. Cross multiply to get
and b = 8. Now for the phase shift. The formula for that is -c/b, and since we already know b, and we have a phase shift value of pi/2, we solve for c:
and
. Therefore,
. Putting all that together into the equation with the A value of 6, we have
. Factoring out the 8 then, the final equation is
, third choice down.
