9 - x² < 0
<u>-9 -9</u> <u> </u><u /> to remove 9 deduct it from both sides<u></u>
- x² < -9
<u> ÷ -1 ÷-1 </u> to remove the negative sign, divide both sides by -1
x² < 9
<u> √x² < √9</u> to remove the exponent of 2, find the square root of both sides.
x < 3 Choice A.
To check:
9 - x² < 0
9 - 3² < 0
9 - 9 < 0
0 < 0
Answer:
The given expression is equal to -5
Step-by-step explanation:
Given that:
= (4−3)−6

= 1-6
Subtracting greater term from smaller gives the negative value
= -5
So the given expression will be equal to -5

Answer:
8000/531441
Step-by-step explanation:
With 25 men and 20 women that means there are 45 people in total. This means the ratio of men to total is 25:45 which we can reduce to 5:9 which means there is a 5/9 chance we would pick a man if we just chose one person. The ratio of women to total is 20:45 which we can reduce to 4:9 meaning there is a 4/9 chance we would pick a women if we just choice one person. When finding probability of multiply things happening we multiply and because this situation is with replacement. So we will multiply
(5/9)(4/9)(4/9)(4/9)(5/9)(5/9)=8000/531441
