Since we are doing flips of a coin, we can agree that each flip is independent of all of the other.

The probability that a coin lands on heads is 1/2, just as the probability that a coin lands on tails is 1/2.

Since each event is independent, we take the probabilities of the events and multiply them together to get the overall probability:

P(H) = 1/2
P(T) = 1/2

So:

P(H, T, H, H, H) = (1/2) x (1/2) x (1/2) x (1/2) x (1/2) = 1/32

The overall probability is 1/32.

Solve for x.<br> 3.rº<br> 80°<br> 20°<br> A. 10<br> B. 20<br> C. 50<br> D. 80
ohaa [14]

Answer:

x = 20°

Step-by-step explanation:

The angle measures should add up to 180 degrees. So that leaves us with 100 degrees left to find if we take out the 80 given.

3x + 2x simplifies to 5x. 5x must equal 100.

100/5 = 20.

Therefore x = 20.

2.1 , - 6/10 , -9/4 , -0.75 , 5/3 , least to greatest
WINSTONCH [101]

Answer:

-9/4, -0.75, -6/10, 5/3, 2.1

Step-by-step explanation:

This is a lot easier to figure out if you simplify the fractions and then change them to decimals

So -9/4 = -2 1/4 or -2.25

-0.75

-6/10 = -0.60

5/3 = 1 2/3 or 1.67

2.1

When you are ordering negatives, the biggest negative is the least. That is why -9/4 (-2.25) is the least number out of the five given.

The next one would be -0.75, because it is the second biggest negative fraction.

The next one is -0.60 because that is the 3rd biggest negative fraction (or the smallest because this is the last negative)

Now, because we're in the positives we start with 1.67, because it is smaller than the other number.

2.1 is our last number, so it is the greatest!

I hope this helped :)
