Answer:

They're all the same distance from 0 on the number line.

If 4 people are selected from a group of 6 married couples, what is the probability that none of them would be married to each o

Ludmilka [50]

Answer:

16/33

Step-by-step explanation:

12C4(total possible outcomes)=495

Since there are 6 married couples there must be 6*[2C2×10C2]=270

must subtracted 15 since when there are 2 couples in a group would have doubled 270-15=255

the no of groupings with no married couples 495-255 =240

probability=no of favourable outcomes /no of possible outcome

probability=240/495= 16/33

Solve -9g+11<-15g-6+7g.

MArishka [77]

Answer: $g>17$

Step-by-step explanation:

$-9g+11$

Move the g-terms to the left side. and the independent terms to the right side. Remember to change the sign if you move from one side to another.

$-9g+15g-7g$

$-16g+15g$

$-g$

Divide by -1 on both sides to make g positive. When it comes to dividing by negatives in inequalities, the inequality sign changes direction.

$\frac{-g}{-1}$

$g>17$
