You have -4,-3,-2, that is a 3 out of a total of 21 points or numbers on the number line. 3/21 is reduces to 1/7.
3 goes into 21 , 7 times. That is why it reduces to 1/7.

Please help u have to factor

Both terms have a $-m^2n$ in common, so we can pull it out. The factored form will be $-m^2n$ times whatever is left after pulling it out.

In the first term, we will have just 8 left since everything else in the term is factored out.

The second term has a $7m^4n^3$ left. Notice that both of these terms no longer have a negative sign since the negative was factored out.

The answer is $(-m^2n)(8+7m^4n^3)$

A simplified model of the human blood-type system has four blood types: A, B, AB, and O. There are two antigens, anti-A and anti

dexar [7]

Answer: Blood type will be A when event "A" happened and event "B" did not happen. Blood type will be B when event "A" did not happened and event "B" happened. Blood type will be AB when both events happened and blood type will be O when both events did not happen.

Step-by-step explanation:

S={AntiA reacts; AntiA does not react; AntiB reacts; AntiB does not react}

If AntiA reacts and AntiB reacts = AB (A∩B)

If AntiA does not react and AntiB does not react= O (A'∩B')

If AntiA reacts and AntiB does not react= A (A∩B')

If AntiA does not react and AntiB reacts= B (A'∩B)
