5) through: (-3, 3), slope = 0​
Elan Coil [88]

Answer:

3

Step-by-step explanation:

We know that -3 is on the x axis and 3 is on the y axis.

and the y axis usually determines if you are going to have a positive slope or negative since it would either rise or decrease. In this cause (-3, 3) shows that 3 is going to be our slope.

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%
