2 9/10 if you round it up but if it is not then its 2 4/5
13 balls are odd in 25
1st pick = 13/25 probability of picking an odd
2nd pick = 12/24 = 1/2 probability
13/25 x 1/2 = 13/50 probability
Answer would be 13/50
Answer:
19.6ft (nearest tenth)
Step-by-step explanation:
Please refer to the attached photo for better understanding.
Given Length of Wire = BC = 22ft
Given Distance from Grounded Wire to Base of Pole = AC = 10ft
Length of Pole = AB
We can use Pythagoras' Theorem to find Length of Pole, AB.
By Pythagoras' Theorem,
1. You have the following equations:
<span>
y=−2x+5 (i)
3x−4y=2 (ii)
2. You must substitute the equation (i) into the equation (ii), as below:
</span>3x−4y=2
3x-4(−2x+5)=2
3x+8x-20=2
11x-20=2
3. Now, you must clear the variable "x":
11x=2+20
x=22/11
x=2
4. You have the value of "x", so you can find the value of "y". When you substitute x=2 into the equation (i), you obtain:
y=−2x+5
y=-2(2)+5
y=-4+5
y=1
5. Therefore, the answer is:
x=2
y=1
