A coin is flipped twice. What is the probability that it will come up once heads and once tails

Mathematics
1 answer:
Illusion [34]3 years ago
5 0

1/2 or 50%, because there are two possibilities out of four.

If you think about flipping a coin twice, there are exactly four possible outcomes:

  Flip 1          Flip 2

1. tails            heads

2. tails            tails

3. heads        tails

4. heads        heads

In two of these possibilities (1 and 3) the coin flipped different sides.

That means 2/4 possibilities matched, and this can be reduced to 1/2

Masco Industries has 285,000 total employees. Of those employees, 85,500 telecommute. What percent of the company’s total employ
frosja888 [35]

Answer:

30%  of the company’s total employees telecommute

Step-by-step explanation:

Masco Industries has 285,000 total employees. Of those employees, 85,500 telecommute.

To find the percentage of company’s total employees telecommute

We divide the number of employees telecommute by total employees

Then we multiply by 100 to get percentage

Percentage = \frac{number \ of  \ telecommute \ employess}{total \ employees} * 100

Percentage = \frac{85500}{285000} * 100

Percentage = 0.3 * 100 = 30%

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 :)
