Answer:
1, 0, and -1
----------------------------------------------
Step-by-step explanation:
|1| < 2 TRUE
|0| < 2 TRUE
|-1| < 2 → |1| < 2 TRUE
All the number in this answer choice are correct.
Remember that the absolute value is a positive number regarding it's sign.

Answer:
Step-by-step explanation:
Given that many couples believe that it is getting too expensive to host an "average" wedding in the United States.
Population mean =24066
Sample mean = 23224
Sample size = 40
Sample std dev = 2903
Since sample std dev is known, we use t critical value.
df =39
Sample mean follows a normal distribution with mean = 23224, and std dev =
t critical value = 2.023
Margin of error = 2.023*459.005
Confidence interval
<span>apples = (50+x)(800-10x)
= (40000-500x+800x-10x^2)
= -10x^2 +300x + 40000
Max occurs when x = -b/(2a) = -30/(-2) = 15
= -x^2 + 30x + 4000
Max occurs when x = -b/(2a) = -30/(-2) = 15
15 trees should be added</span>
The speaker is the encoder. That is the correct answer B.
Answer:
x = 3
Step-by-step explanation:
The right triangles are all similar, so the ratio of short leg to hypotenuse is the same for both marked triangles.
short leg / hypotenuse = x/(x+3) = (x+3)/12
12x = (x +3)^2 . . . . . multiply by 12(x+3)
x^2 -6x +9 = 0 . . . . put in standard form
(x -3)^2 = 0 . . . . . . . factor
x = 3 . . . . . the value of x that makes the factor(s) zero
