Answer:
2/13
Step-by-step explanation:
There are 6 + 4 + 3 = 13 balls all together.
If the first one is green, this will happen with a probability of 4/13. Now there are 12 balls left
There are 6 red balls. 6/12 = 1/2
The probability of the way this happens is 1/2 * 4/13 = 2/13
<u>Answer:</u>
No, incorrect. It should be -13. 56 unit
<u>Step-by-step explanation:.</u>
I am overcharged 4.52 unit on my cell phone 3 months in a row.
So, net amount I am overcharged = 
unit
= 13.56 unit
So, in the next bill there should be an adjustment of - 13.56 unit. But, here it is given - 13.28 unit only. So, this is incorrect.
Answer: 0.50, which is choice b
Explanation:
The interval 
covers 5-1 = 4 units in the horizontal direction.
This is out of 8 units that span from x = 0 to x = 8 (we could say 8-0 = 8).
So we get the final result of 4/8 = 0.50
In other words, the interval from x = 1 to x = 5 covers exactly half of the interval from x = 0 to x = 8.
Answer:
I think it's choice B and D
Step-by-step explanation:
they both are a straight line and would both have a slope of zero. between point A and D is a slope obviously but D and F would not be the same slope because the line gets steeper. that's how I look at it. I'm pretty sure that's it.
Answer:
When t=2.1753 & t=.5746 , h=27
Don't worry, I got you. Also, my calculator does too.
We set h equal to 27, because we want the height to be 27 when we solve for t.
That leaves us with:
27 = 7 + 44t - 16t^2
Simplify like terms,
20 = 44t - 16t^2
Move 20 onto the right side, so we can use quadratic equation
44t - 16t^2 - 20 = 0 --> -16t^2 + 44t - 20
Using quadratic, you get
t=2.1753 & t=.5746
<u>poster confirmed : "It’s t=2.18 and t=0.57"</u>
