Answer:
i believe the median is three
1) you have to add all the rings together to find the denominator
6 + 11 + 15 + +3 = 35
2) the numerator is the amount of rings of the certain color you are trying to find the probability of
15
3) find the theoretical probability! 15/35
4) simplify
15/35 (divide both by 5) = 3/7
hope it helped :)
Yep!
Weighing #1: Start off by splitting the pile of 12 coins evenly into two piles, 6 in each pile. Put one pile on each side of the balance. The side that is weighed down has the fake coin it in. Ignore the other 6 coins.
Weighing #2: Now you have 6 coins left. Split the pile evenly again, 3 in each pile. Repeat the same process and put each pile on one side of the balance. The side that is weighed down has your fake coin in it. Ignore the other 3 coins.
Weighing #3: You have 3 coins left. Take two coins, whichever two you like, and weigh them. If they weigh the same, then the one you didn't weigh is the fake one. If one is heavier, then that heavier one is your fake coin.
Answer:
simplify = - 4 x -2 factored = 2 (-2x - 1)
Step-by-step explanation:
Hello! :)
Answer:
*The answer must have a POSITIVE sign!*
Step-by-step explanation:
Expand with distributive property: a(b+c)=ab+ac
4*5=20
6*4=24
20x-24
2*8=16
2*10=20
16x+20
20x-24=16x+20
First, you add by 24 both sides of an equation.
20x-24+24=16x+20+24
20x=16x+44
You subtract by 16x both sides of an equation.
20x-16x=16x+44-16x
4x=44
Then, you divide by 4 both sides of an equation.
4x/4=44/4
Divide by the numbers from left to right.
44/4=11
<u><em>X=11 is the final answer</em></u>
Hope this helps!
Have a nice day! :)
