Flip the coin three times and record your results. While we know the theoretical probability of flipping a heads, what is the ex
ivann1987 [24]

The probability of getting heads while flipping a coin for three times is 1/2

<u>Explanation:</u>

When a coin is flipped then there are two possible outcomes.

We can either get a heads or a tail.

If a coin is flipped three times and the possibility of getting heads would be 3

Total number of outcomes would be 6 ( 2 possible outcomes X 3 times toss)

Therefore, probability of getting heads would be = 3/6

                                                                                     = 1/2

Therefore, the probability of getting heads while flipping a coin for three times is 1/2

A fish fank was 3/4 full, and then 1/3 of the water leaked out,
QveST [7]

Answer:

5) It was 5/12 of the way full

6) It holds 48 gallons.

Step-by-step explanation:

For #5, you can simply find the lowest common denominator, which was 12, so you would multiply 3/4 by 3/3 and 1/3 by 4/4, giving you 9/12 and 4/12. Next you would subtract 4 from 9 and get the answer 5/12.

For #6 you can set up the problem as a ratio, 5/12 and 20/x, and then cross multiply, getting the equation 5x = 240. Then divide by 5 and you get the answer 48.

Hope this helps!!

What is the value of x? <br><br> __mm
andrezito [222]

Answer:

161.91

Step-by-step explanation:

First find the side length or YT by using the pythagorean theorem.

c= 129.2^2 = 16692.64

b= 68^2=4624

c-b = 12068.64

The square root of 12068.64 is approximately 109.86.

Using that length use the pythagorean theorem again and so:

a = 109.86^2 = 12068.64

c = 57^2 = 3249

a-c = 8819.64

The square root of 8819.64 is approximately 93.91.

So, 68 + 93.91 = 161.91
