3.9 and 5.3, when rounded off and mult. together, produce the product 20.
Thus, the decimal point must follow the first two digits of your answer, whether estimate or "exact."

3.9*5.3 = 20.67 by calculator.

If a denotes some​ event, what does upper a overbar ​denote? if ​p(a)equals0.992​, what is the value of ​p(upper a overbar​)?
ELEN [110]

If A denotes some event, what does Ā denote?

If P(A) = 0.992, what is the value of P(Ā)?

Answer :

A denotes some event , Ā denotes the complement of A that is Ā contains all the events that does not occur in A.

Given: P(A) = 0.992

We know total probability =1

P(A) + P(Ā)= 1

P(Ā)= 1 - P(A)

P(Ā)= 1 - 0.992 = 0.008

P(Ā) = 0.008

To answer the question for all the missing operations are either: add, subtract , multiply , or divide.
Alexeev081 [22]

question a is divide. 48 divided by -8 is -6.

question b is divide. -40 divided by 8 is -5.

question c is subtract. The negative sign on the 2 and the minus symbol cancel out.

question d is add. If you put a minus sign, the signs would cancel out and become addition.

question e is add. If you put a minus sign, the signs would cancel out and become addition.

question f is multiply. Half of 22 is 11 and the 0.5 is negative.

Divide the binomial by the monomial to find the quotient -36x^4y + 144x^2 y^6/ -4x^2y
elixir [45]
The way that you would do this is by taking -4x^{2} out of the binomial, or as I like to think about it, 'un-distributing'. :p
-4x^{2} out of -36x^{2}y, you end up with 12x^{2}. 
When you take -4x^{2} out of 144x^{2}y{6}, you get -36y^{5}. 
Put it together, and the solution is 12x^{2} - 36y^{5}.

Hope I helped!!
