8 0

Answer:

The 8 should have remained positive.

Step-by-step explanation:

8-(-2)=8+2=10

Two negatives make a positive so 8-(-2) will turn into 8+2.

Laura was wrong because she thought the 8 turned to a negative but that makes no sense.

If A and B are independent events and P(A)=0.25 and P(B)=0.333, what is the probability P(ANB)?
Pachacha [2.7K]

The probability P(ANB), that is, P(A ∩ B), given that A and B are independent events and P(A) = 0.25 and P(B) = 0.333 is <u>0.08325</u>. Hence, <u>option C</u> is the right choice.

For any two events A and B, the probability of event A and B, that is, P(A ∩ B) is given as:-

  1. When the events are dependent, P(A ∩ B) = P(A).P(B|A).
  2. When the events are independent, P(A ∩ B) = P(A).P(B).

In the question, we asked the probability P(ANB), that is, P(A ∩ B), given that A and B are independent events and P(A) = 0.25 and P(B) = 0.333.

We know that when the events are independent, P(A ∩ B) = P(A).P(B).

Thus, P(A ∩ B) = (0.25)*(0.333),

or, P(A ∩ B) = 0.08325.

Thus, the probability P(ANB), that is, P(A ∩ B), given that A and B are independent events and P(A) = 0.25 and P(B) = 0.333 is <u>0.08325</u>. Hence, <u>option C</u> is the right choice.

Serjik [45]

Answer:

Yes, they are being underrepresented.

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.

The Population of African Americans in St. Louis suburbs 5.7% . Therefore we can assume that the school system should have about 5.7% of their teachers being African Americans. Since we are given the amount of total teachers and the amount of African American teachers in the school, we can calculate the percent of African American teachers by using a simple Rule of Three property (demonstrated in the picture below).

405 Total teachers   ⇒   100%

15 African American   ⇒   x

\frac{15*100}{405} = x

3.7% = x

We can see that approximately 3.7% of the School Teachers are African Americans, So we can say they are being underrepresented.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
