1/6 would be the fraction of 1/2+1/3= 1/6!

Answer:  \frac56

Work Shown:

\frac{1}{2}+\frac{1}{3}\\\\\frac{3}{6}+\frac{2}{6}\\\\\frac{3+2}{6}\\\\\frac{5}{6}\\\\

To visualize this, cut up a circle into 6 equal pieces.

3 of those pieces represent half the circle (3/6 = 1/2)

2 more pieces represent one third (2/6 = 1/3)

We have 3+2 = 5 pieces out of 6 total. This is visual confirmation that 1/2 + 1/3 = 5/6

All athletes at the Olympic games are tested for performance-enhancing steroid drug use. The imperfect test gives positive resul
Nana76 [90]

Answer:

0.4%

Step-by-step explanation:

We have two independent events

  1. The athlete who is being tested for drugs actually is using steroids.
  2. The test went wrong indicating a false result.

The probability of 1) to happen is 0.04 because "4% of all registered athletes use steroids".

The probability of 2) ti happen is 0.1 because "The imperfect test gives positive results (indicating drug use) for 90% of all steroid-users"

Then the probability of 1) and 2) to happen is given by

P=P(1)*P(2)=(0.04)(0.1)=0.004=0.4%

Tanya [424]

Answer:

The expression that represents hourly rate Brendan earns working on a holiday is 1.25d.

Step-by-step explanation:

Given:

Regular hourly rate = d

Percent extra Money earned on holidays = 25% more

We need to find expression represent the hourly rate Brendan earns working on a holiday.

Solution:

Extra money earned on holidays can be calculated by Percent extra Money earned on holidays multiplied by Regular hourly rate.

framing in equation form we get;

Extra money earned on holidays = \frac{25}{100}d=0.25d

Now we will find hourly rate Brendan earns working on a holiday.

hourly rate Brendan earns working on a holiday can be calculated by sum of Regular hourly rate plus Extra money earned on holidays.

framing in equation form we get;

hourly rate Brendan earns working on a holiday = d+0.25d=d(1+0.25) =1.25d

Hence The expression that represents hourly rate Brendan earns working on a holiday is 1.25d.
