This is the same as averaging. You add them and divide by 2.
((m/n) + (p/q))/2 would be a number in between m/n and p/q.
Do note that n and q must be nonzero, but luckily that is a given.
Answer:
(4b-9) (4b+9)
Step-by-step explanation:
16b^2 – 81
This is the difference of squares
(a^2 -c^2) = (a-c) (a+c)
a^2 = 16b^2 so a= 4b
c^2 = 81 so c = 9
(16b^2 – 81) = (4b-9) (4b+9)
Well this depends a lot about what your variable represents in this problem since if you have like -12 is greater than 24(-5). So it really just depends on your variable but if it's just -12 and 24 then 24 is greater than -12. So -12 is less than 24.
Answer:
7920 possible outcome
Step-by-step explanation:
There are 4 Board of Directors positions open.
2 will be for men, 2 will be for women.
Totak number of candidates= 20
Total men= 11
Total women= 9
The probability
=(11C2*9C2)/20C4
= (55*36)/4845
=1980/4845
= 0.41
Total outcome = (11P2 * 9P2)
=110 * 72
= 7920
For this case we must resolve the following inequality:
Subtracting 7 from both sides of the inequality we have:
Dividing by 3 to both sides of the inequality we have:
We multiply by -1 on both sides, taking into account that the sense of inequality changes:
Thus, it is observed that to solve the inequality it is necessary to change the meaning of it.
ANswer:
False. It is necessary to change the sense of inequality
